This contradiction proves the theorem when \( r > 5 \). The results 7, 29, 97, 389, and 1543 show that the theorem is also true for \( r \leq 5 \). The proof of Bertrand's Postulate by this method is left as an exercise. Bertrand's Postulate may be used to prove the following results. 1. \(\frac{1}{n} \sum_{p \leq n} \frac{1}{p} \text{ is never an integer.}\) 2. Every integer \( > 6 \) can be written as the sum of distinct primes. 3. Every prime \( p_n \) can be expressed in the form \[ p_n = 2 + 3 + 5 + \cdots + p_{n-1} \] with an error of most 1 (Sierk). 4. The equation \( \pi(n) = \psi(n) \) has exactly 8 solutions. About 1949 a sensation was created by the discovery by Erdős and Selberg of an elementary proof of the Prime Number Theorem. The main new result was the following estimate, proved in an elementary manner: \[ \sum_{p \leq x} \log p \sim 2x \log x + O(x). \] Although Selberg's inequality is still far from the Prime Number Theorem, the latter can be deduced from it in various ways without recourse to any further number theoretical results. Several proofs of this lemma have been given, perhaps the simplest being due to Tzwarzow and Szelk. Selberg's original proof depends on consideration of the functions \[ \lambda_n = \mu_n = \sum_{d \mid d} \mu(d) \frac{1}{d^2} \] and \[ T(r) = \sum_{n=1}^{r} \lambda^2. \] Some five years ago J. Landeck and L. Moser showed that one could prove Selberg's lemma in a completely elementary way, i.e., using properties of integers only. One of the main tools for doing this is the following rational analogue of the logarithmic function. Let \[ h(r) = \frac{1}{1 + \frac{1}{2} + \frac{1}{3} + \cdots + \frac{1}{r}}. \] We prove in an quite elementary way that \[ |h(e) - h(c)| < \frac{1}{k}. \] The results we have established are useful in the investigation of the magnitudes of the arithmetic functions \( \sigma(n) \), \( \phi(n) \) and \( g(n) \). Since these depend not only on the magnitude of \( n \) but also strongly on the arithmetic structure of \( n \), we cannot expect to approximate them by the elementary functions of analysis. Nevertheless, we shall will see that “on average” these functions have a rather simple behavior. Let \( f \) and \( g \) be functions for which \[ f(1) + f(2) + \cdots + f(n) + g(1) + g(2) + \cdots + g(n), \] we say that \( f \) and \( g \) have the same average order. We will see, for example, that the average order of \( \sigma(n) \) is long, that of \( \phi(n) \) is \(\frac{n}{\log n}\). Let us consider first a purely heuristic argument for obtaining the average value of \( a(n) \). The probability that \( r \mid n \) and \( r \leq 1 \) contributes \( \left( \frac{1}{k} \right)^r \) to \( a(n) \). Thus the expected value of \( a(n) \) is \[ \frac{1}{T(r)} \left( \sum_{k=1}^{1} \frac{1}{k} + 1 + \frac{1}{k} \right). \] For \( k = 0 \) this will be about \( \log n \). For \( n \geq 1 \) it will be about \( n^{k}(k + 1) \), e.g., for \( n = 1 \) it will be about \( n(k^2) = n^2 + \frac{1}{k^2} \). Before proceeding to the proof and refinement of some of these results we consider some applications of the inversion of order of summation in certain double sums.

Let \(n\) be a given integer. We want to find out if \(n\) is prime. The method that we choose is the following. For each integer \(m = 2, 3, \ldots, \sqrt{n}\)| we ask if \(m\) divides (evenly into) \(n\). If all of the answers are ‘No,’ then we declare \( n \) to be a prime number, else it is composite. First, we look at the computational complexity of this algorithm. That means that we are going to find out how much work is involved in doing the test. For a given integer \( n \) the work that we have to do can be measured in units of divisions of a whole number by another whole number. In those units, we obviously will do about \(\sqrt{n}\) units of work. It seems as though this is a tractable problem, because, after all, \(\sqrt{n}\) is of polynomial growth in \( n \). For instance, we do less than \( n \) units of work, and that’s certainly a polynomial in \( n \), isn’t it? So, according to our definition of fast and slow algorithms, the distinction was made on the basis of polynomial vs. faster-than-polynomial growth of the work done with the problem size, and therefore this problem must be easy. Right? Well, no not really. References to the distinction between fast and slow methods will show that we have to measure the amount of work done as a function of the number of bits of input to the problem. In this example, \( n \) is not the number of bits of input. For instance, if \( n = 59 \), we don’t need 59 bits to describe it, but only 6. In general, the number of binary digits in the bit string of an integer \( n \) is close to \(\log_2 n\). So in the problem of this example, testing the primality of a given integer \( n \), the length of the input bit string \( B \) is about \(\log_2n\). Seen in this light, the calculation suddenly seems very long. A string consisting of mere \(\log_2 n\) 0’s and 1’s has caused our mighty computer to do about \(\sqrt{n}\) units of work. If we express the amount of work done as a function of \( B \), we find that the complexity of this calculation is approximately \(2^{B/2}\), and that grows much faster than any polynomial function of \( B \). Therefore, the method that we have just discussed for testing the primality of a given integer is slow. See Chapter 4 for further discussions of this problem. At the present time no one has found a fast way to test for primality, nor has anyone proved that there isn’t a fast way. Primality testing belongs to the (well-populated) class of seemingly, but not provably, intractable problems. In this book we will deal with some easy problems and some seemingly hard ones. It’s the ‘seemingly’ that makes things very interesting. These are problems for which no one has found a fast computer algorithm, --- ### Scene and Activity Analysis: #### Described Scene and Activities: - The scene described in the image is a text-heavy document discussing computational problems, particularly focusing on the complexity and computational time of algorithms. - There are discussions of worst-case bounds, average case bounds, and the difference between fast and slow algorithms, followed by an example problem regarding the determination of whether a given integer is prime. #### Main Actors: - The main actors in the scene are algorithms and computational problems. - The text describes the actions of measuring computational complexity, evaluating polynomial vs. non-polynomial time, and testing algorithm efficiency. ### Contextual Significance: #### Contribution to Overall Message: - This text excerpt appears to be from a textbook or academic paper focusing on computational complexity, likely aimed at explaining the difference between easy and hard problems in computer science. - The example provided (primality testing) is used to illustrate these concepts and highlight the challenges associated with algorithm efficiency. ### Perspective and Composition: #### Perspective: - The perspective is that of a reader or student studying the material presented on the page. #### Composition: - The text is organized in a traditional scholarly format, with clear headings, paragraphs, and a structured presentation of concepts and examples. ### Anomaly Detection: - No anomalies were detected in the image; the text appears to be consistent with a standard academic document discussing computational complexity. ### Color Analysis: #### Color Composition: - The image consists entirely of black text on a white background. #### Dominant Colors: - The dominant colors are black and white. ### Graph and Trend Analysis: - There are no graphs present in this image. ### Diagram and Chart Analysis: - There are no diagrams or charts present in this image. ### Metadata Analysis: - There is no visible metadata within the image. ### Additional Aspects: #### Prozessbeschreibungen (Process Descriptions): - The described process is related to evaluating the computational complexity of algorithms, specifically mentioning worst-case and average-case scenarios and providing an example with testing for primality. #### Typen Bezeichnung (Type Designations): - Type designations include polynomial-time algorithms and non-polynomial-time algorithms, as well as tractable and intractable problems. ### Conclusion: This image contains a detailed section of text from what appears to be a textbook or academic paper on computational complexity, focusing on the difference between easy and hard computational problems, with a specific example relating to primality testing.

Given \( n \). Output \( n \) is composite if \(\gcd(n, b) \neq 1\), else output `inconclusive`. This one is a little better, but not yet good. If \( n \) is composite, the number of bases \( b \leq n \) for which Test 2 will produce the result `composite` is \( n - \varphi(n) \), where \(\varphi\) is the Euler totient function (of 4.1.5). This number of useful bases will be large if \( n \) has some small prime factors, but in that case it’s easy to find out that \( n \) is composite by other methods. If \( n \) has only a few large prime factors, say \( n = p^k \), then the proportion of useful bases is very small, and we have the same kind of inefficiency as in Test 1 above. Now we can state the third pseudoprimality test. Test 3. Given \( n \). (If \( b \) and \( n \) are not relatively prime or) if \( b \neq 1 \) (mod \( n \)), then output \( n \) is composite; else output `inconclusive`. Regrettably, the test is still not `good`, but it’s a lot better than its predecessors. To cite an extreme case of its un-goodness, there exist composite numbers \( n \), called Carmichael numbers, with the property that the pair \( (n, b) \) produces the output `inconclusive` for every integer \( b \in [1, n-1] \) that is relatively prime to \( n \). An example of such a number is \( n = 1729 \), which is composite (\(1729 = 17 \times 101\)), but for which Test 3 gives the result `inconclusive` on every integer \( b < 1729 \) that is relatively prime to 1729 (i.e., that is not divisible by \( 7 \) or \( 13 \) or \( 19 \)). Despite such misbehavior, the test usually seems to perform quite well. When \( n = 169 \) (a difficult integer for Tests 1 and 2) it turns out that there are 158 different \( b \in [1, 168] \) that produce the `composite` outcome from Test 3, namely every such \( b \) except for \( 19, 22, 23, 70, 80, 89, 96, 147, 150, 168 \). Finally, we will describe a good pseudoprimality test. The familial resemblance to Test 3 will be apparent. Test 4. (The strong pseudoprimality test): Given \( (n, k) \). Let \( n - 1 = 2^m \cdot q \), where \( m \) is an odd integer. If either - (a) \( b^m \equiv 1 \) (mod \( n \)) or - (b) there is an integer \( i \in [0, q - 1] \) such that \( b^{2^i \cdot q} \equiv -1 \) (mod \( n \)) then return `inconclusive`; else return `n is composite`. First we validate the test by proving the **Proposition.** If the test returns the message `n is composite`, then \( n \) is composite. **Proof.** Suppose not. Then \( n \) is an odd prime. We claim that: \[ b^{m} \equiv 1 \text{ (mod } n) \] for all \( i = 0, q - 1, \ldots, 0 \). If so then the case \( i = 0 \) will contradict the outcome of the test, and thereby complete the proof. To establish the claim, it is clearly true when \( i = q \) by Fermat's theorem. If true for \( i \) it is true for \( i - 1 \), because \[ (b^{2^{i-1}})^2 = b^{2^i} \equiv 1 \text{ (mod } n) \] implies that the quantity being squared is \( +1 \) or \( -1 \). Since \( n \) is an odd prime, by corollary 4.5.3 \( U_n \) is cyclic, and so the equation \( x^2 \equiv 1 \) in \( U_n \) has only the solutions \( x \equiv \pm 1 \). But \( -1 \) is ruled out by the outcome of the test, and the proof of the claim is complete. What is the computational complexity of the test? Consider first the computational problem of raising a number to a power. We can calculate, for example, \( b^k \) mod \( n \) with \( O(\log k) \) integer multiplications, by successive squaring. More precisely, we compute \( b^1, b^2, b^4, b^8, \ldots \) by squaring, and reducing modulo \( n \) immediately after each squaring operation, rather than waiting until the final exponent is reached. Then we use the binary expansion of the exponent to tell us which of these powers of \( b \) we should multiply together in order to compute \( b^n \). For instance, \[ b^{37} = b^{32} \cdot b^{4} \cdot b^{1}. \] Image Analysis: ### Analysis of the Visual Content **1.

If \( B' \) generates the full group \( U_n \), then \( B \) does too, and by lemma 4.7.2, if \( n \) is a prime power, \( n = p^k \). Also, in either of the above cases we have \( b^{\phi(n)} \equiv 1 \), so the same holds for all \( b \in B' \), and so for all \( x \in U_n \), we have \( x^{n-1} \equiv 1 \), since \( B' \) generates \( U_n \). Now, \( n \) is cyclic or direct. By theorem 4.5.3 there are primitive roots modulo \( n = p^k \). Let \( g \) be one of these. The order of \( g \) is, on the one hand, \( p^{k-1}(p-1) \) since the set of all its powers is identical with \( U_n \), and on the other hand is a divisor of \( n - 1 = i^{k} - 1 \) for all \( a \), and in particular for \( a = g \). Hence \( p^{k-1}(p - 1) \) (which, if \( k > 1 \), is a multiple of \( p \)) divides \( p \) (which is one less than a multiple of \( p \)), and so \( k = 1 \), which completes the proof of part (a) of the theorem. In part (b), \( n \) is composite and so \( B' \) cannot generate all of \( U_n \) by part (a). Hence \( B' \) generates a proper subgroup of \( U_n \), and so can contain at most half as many elements as \( U_n \) contains, and the proof is complete. Another application of the same circle of ideas to compute elements occurs in the generation of random numbers on a computer. A good way to do this is to choose a primitive root modulo the word size of your computer, and then, each time the user asks for a random number, output the next higher power of the primitive root. The fact that you started with a primitive root insures that the number of "random numbers" generated before repetition sets in will be as large as possible. Now we'll summarize the way in which the primality test is used. Suppose there is a large integer \( n \), and we would like to determine if it is prime. We can do this with: ``` function test(n, outcome); times = 0; repeat choose an integer \( k \) uniformly at random in \( [2, n-1] \); apply the strong pseudoprimality test (Test 4) to the pair \( (n, k) \); times = times + 1 until \( (result = 'is composite') \text{ or times = 100} \; if times = 100 then outcome := 'is probably prime' else outcome := 'is composite' end{test} ``` If the procedure exits with \( n \) is composite, then we can be certain that \( n \) is not prime. If we want to see the factors of \( n \) then it will be necessary to use some factorization algorithm, such as the one described below in section 4.9. On the other hand, if the procedure halts because it has been through 100 trials without a conclusive result, then the integer \( n \) is very probably prime. More precisely, the chance that a composite integer \( n \) would have behaved like that is less than \( 2^{-100} \). If we want certainty, however, it will be necessary to apply a test whose outcome will prove primality, such as the algorithm of Adleman, Rumely and Pomerance, referred to earlier. In section 4.9 we will discuss a probabilistic factoring algorithm. Before doing so, in the next section we will present a remarkable application of the complexity of the factoring problem to cryptography. Such applications remind us that primality and factorization algorithms have important applications beyond pure mathematics, in areas of vital public concern. ## Exercises for section 4.7 1.

However if neither \( u \equiv v \,(\text{mod } n) \) nor \( u \equiv -v \,(\text{mod } n) \) is true then we will have found a nontrivial factor of \( n \), namely \(\gcd(u - v, n)\) or \(\gcd(u + v, n)\). ## Example: Take as a factor base \( B = \{-2, 5\} \), and let it be required to find a factor of \( n = 1729 \). Then we claim that 186 and 267 are \( B \)-numbers. To see that 186 is a \( B \)-number, note that \( 186 \equiv 20 - 1729 + (-2)^{4} \); and similarly, since \( 267 \equiv 41 - 1729 + (-2)^{5} \), we see that 267 is a \( B \)-number for this factor base \( B \). The exponent vectors of 186 and 267 are \( (4, 0) \) and \( (4, 2) \) respectively, and these sum to \( (0, 1) \) (mod 2), hence we find that \[ u = 186 \times 267 = 1250 \quad (\text{mod } 1729) \\ r_1 = 4; \; r_2 = 1 \\ r_1 = 4; \; r_2 = 1 \\ v = (-2)^{5} = 80 \\ \gcd(u - v, n) = \gcd(1170, 1729) = 13 \] and we have found the factor 13 of 1729. There might have seemed to be some legerdemain involved in plucking the \( B \)-numbers 186 and 267 out of the air, in the example above. In fact, as the algorithm has been implemented by its author, J. D. Dixon, one simply chooses integers uniformly at random from \([1, n-1]\) until enough \( B \)-numbers have been found, so their exponent vectors are linearly dependent modulo 2. In Dixon's implementation the factor base that is used consists of \( -1 \) together with the first \( k \) prime numbers. It can then be proved that if \( n \) is not a prime power then with a correct choice of \( b \) relative to \( n \), if we repeat the random choices until a factor of \( n \) is found, the average running time will be \[ \exp\left(2 + o(1)\right)(\log \log n)^{\frac{3}{2}} \] This is not polynomial time, but it is moderately exponential only. Nevertheless, it is close to being about the best that we know how to do on the elusive problem of factoring a large integer. ## 4.10 Proving primality In this section we will consider a problem that sounds a lot like primality testing, but is really a little different because the rules of the game are different. Basically the problem is to convince a skeptical audience that a certain integer is prime, requiring them to do only a small amount of computation in order to be so persuaded. First, though, suppose you were writing a 100-decimal-digit integer on the blackboard in front of a large audience and you wanted to prove to them that it was not a prime. If you simply wrote down two smaller integers whose product was \( n \), the job would be done. Anyone who wished to be certain could spend a few minutes multiplying the factors together and verifying the product was indeed \( n \), and all doubts would be dispelled. Indeed*, a speaker at a mathematical convention in 1903 announced the result that \( 2^{n} - 1 \) is not a prime number, and to be utterly convincing all he had to do was to write \[ 2^{n} - 1 = 193707721 \times 76813832752787. \] We note that the speaker probably had to work very hard to find those factors, but having found them it became quite easy to convince others of the truth of the claimed result.

However if neither \( u \equiv v \, (\text{mod} \, n) \) nor \( u \equiv -v \, (\text{mod} \, n) \) is true then we will have found a nontrivial factor of \( n \), namely \(\gcd(u - v, n)\) or \(\gcd(u + v, n)\). ## Example: Take as a factor base \( B = \{-2, 5\} \), and let it be required to find a factor of \( n = 1729 \). Then we claim that 186 and 267 are B-numbers. To see that 186 is a B-number, note that \( 186^2 \equiv 20 \, \text{(mod} \, (-2)^2) \), and similarly, since \( 267^2 \equiv 41 - 1729 + (-2)^2 \), we see that 267 is a B-number, for this factor base \( B \). The exponent vectors of 186 and 267 are \( (4, 0) \) and \( (4, 2) \) respectively, and these sum to \( (0, 0) \) (mod 2), hence we find that \[ u = 186 \times 267 = 1729 \, (\text{mod} \, 1729) \] \[ r_1 = 4; \quad r_2 = 1 \] \[ s_1 = (-2)^{(5)} = 80 \] \[ \gcd(u - v, n) = \gcd(1170, 1729) = 13 \] and we have found the factor 13 of 1729. There might have seemed to be some legerdemain involved in plucking the B-numbers 186 and 267 out of the air, in the example above. In fact, as the algorithm has been implemented by its author, J. D. Dixon, one simply chooses integers uniformly at random from \([1, n-1]\) until enough B-numbers have been found, so their exponent vectors are linearly dependent modulo 2. In Dixon's implementation the factor base that is used consists of \( 1 \) together with the first \( k \) prime numbers. It can then be proved that if \( n \) is not a prime power then with a correct choice of \( b \) relative to \( n \), if we repeat the random choices until a factor of \( n \) is found, the average running time will be \[ \exp\left(2 + o(1)\right)(\log \log n)^{3}. \] This is not polynomial time, but it is moderately exponential only. Nevertheless, it is close to being about the best that we know how to do on the elusive problem of factoring a large integer. ## 4.10 Proving primality In this section we will consider a problem that sounds a lot like primality testing, but is really a little different because the rules of the game are different. Basically the problem is to convince a skeptical audience that a certain integer \( n \) is prime, requiring them to do only a small amount of computation in order to be so persuaded. First, though, suppose you were writing a 100-decimal-digit integer on the blackboard in front of a large audience and you wanted to prove to them that it was not a prime. If you simply wrote down two smaller integers whose product was \( n \), the job would be done. Anyone who wished to be certain could spend a few minutes multiplying the factors together and verifying that the product was indeed \( n \), and all doubts would be dispelled. Indeed*, a speaker at a mathematical convention in 1903 announced the result that \( 2^{n} - 1 \) is not a prime number, and to be utterly convincing all he had to do was to write \[ 2^{n} - 1 = 193707721 \times 761838257287. \] We note that the speaker probably had to work very hard to find those factors, but having found them it became quite easy to convince others of the truth of the claimed result.

How might we convince an audience that a certain integer $n$ is a prime number? The rules are that we are allowed to do any immense amount of calculation beforehand, and the results of that calculation can be written on a certificate $C(n)$ that accompanies the integer $n$. The audience, however, will need to do only a polynomial amount of further computation in order to convince themselves that $n$ is prime. We will describe a primality-checking algorithm $A$ with the following properties: 1. If $n$ is prime then the action of $A$ on the input $C(n)$ results in the output `it is prime.’ 2. If $n$ is prime then for every possible certificate $C'(n)$ the action of $A$ on the input $C'(n)$ results in the output `primality of $n$ is not verified.’ 3. Algorithm $A$ runs in polynomial time. Now the question is, does such a procedure exist for primality verification? The answer is affirmative, and we will now describe one. The fact that primality can be quickly verified, if not quickly discovered, is of great importance for the developments of Chapter 5. In the language of section 5.1, what we are about to do is to show that the problem `Is $n$ prime?’ belongs to the class NP. The next lemma is a kind of converse to Fermat’s little theorem (theorem 4.5.2): ### Lemma 4.10.1 Let $p$ be a positive integer. Suppose there is an integer $x$ such that $x^{p-1} \equiv 1 \ (\text{mod } p)$ and such that for all divisors of $p-1$, $1 < d < p-1$, we have $x^{d} \not\equiv 1 \ (\text{mod } p)$. Then $p$ is prime. **Proof:** First we claim that $\gcd(x, p) = 1$, for let $g = \gcd(x, p)$. Then $g | p$, so $g = 1$ or $g = p$. Since $x^{p-1} \equiv 1 \ (\text{mod } p)$, we have $x^{p-1} \equiv 1 + tp$ for some integer $t$. So the right side is not zero unless $g = 1$. It follows that $x \in U_{p}$, the group of units of $\mathbb{Z}_{p}$. Thus $x$ is an element of order $p-1$ in a group of order $\varphi(p)$. Hence $\varphi(p) \leq p-1$. Since $\varphi(p) = p-1$ if $p$ is prime. Lemma 4.10.1 is the basis for V. Pratt’s method of constructing certificates of primality. The construction of the certificate is actually recursive since step 3b below calls for certificates of smaller primes. We suppose that the certificate of the prime 2 is the trivial case, and that it can be verified at no cost. Here is a complete list of the information that is on the certificate $C(p)$ that accompanies an integer $p$ with primality to be attested to: 1. $\mathcal{P}$: a list of the primes $p_i$ and the exponents $a_i$ for the canonical factorization $p - 1 = \prod_{i=1}^{k} p_i^{a_i}$. 2. $\mathcal{C}$: the certificates $C(p_i)$ of each of the primes $p_1,\ldots,p_k$. 3. $x$: a positive integer $x$. To verify that $p$ is prime we could execute the following algorithm $B$: 1. (B1) Check that $p - 1 = \prod_{i=1}^{k} p_i^{a_i}$. 2. (B2) Check that each $p_i$ is prime, using the certificates $C(p_i) \; (i = 1,\ldots,k)$. 3. (B3) For each divisor $d$ of $p - 1$, $1 < d < p - 1$, check that $x^{d} \not\equiv 1 \ (\text{mod } p)$. 4. (B4) Check that $x^{p-1} \equiv 1 \ (\text{mod } p)$. This algorithm $B$ is correct, but it might not operate in polynomial time. In step B3 we are looking at every divisor of $p - 1$, and there may be a lot of them. Fortunately, it isn’t necessary to check every divisor of $p - 1$. The reader will have no trouble proving that there is a divisor of $p - 1$ for which $x^{d} \equiv 1 \ (\text{mod } p)$ if and only if there is such a divisor that has the special form $(p - 1)/y$. The primality checking algorithm $A$ now reads as follows: 1. (A1) Check that $p - 1 = \prod_{i=1}^{k} p_i^{a_i}$. 2. (A2) Check that each $p_i$ is prime, using the certificates $C(p_i) \; (i = 1,\ldots,k)$. 3. (A3) For each $i = 1$ to $k$, check that $x^{(p-1)/y} \not\equiv 1 \ (\text{mod } p)$.

The next lemma is a kind of converse to 'Fermat's little theorem' (theorem 4.52). ## Lemma 4.10.1 Let \( p \) be a positive integer. Suppose there is an integer \( x \) such that \( x^{p-1} \equiv 1 \ (\text{mod } p) \) and such that for all divisors of \( p-1, 1 < d < p-1 \), we have \( x^d \not\equiv 1 \ (\text{mod } p) \). Then \( p \) is prime. **Proof:** First we claim that \( \gcd(x, p) = 1 \), for let \( g = \gcd(x, p) \). Then \( g \) divides \( x^{p-1} \equiv 1\ (\text{mod } p) \). Since \( x^{p-1} \equiv 1 \), the right side is \( 1 + tp \) and \( x^{p-1} - tp \equiv 1 \). The left side is a multiple of \( g \). It follows that \( g \) divides \( x^{p-1} - 1\). Thus \( g \) is an element of order \( p-1 \) in a group of order \( \varphi(p) \). Hence \( \varphi(p) \leq p-1 \). Since \( \varphi(p) = p - 1 \) and \( p \) is prime. Lemma 4.10.1 is the basis for V. Pratt's method of constructing certificates of primality. The construction of the certificate is actually recursive since step 3b allows for certificates of smaller primes. We suppose that the certificate of the prime \( 2 \) is the trivial case, and that it can be verified at no cost. Here is a complete list of the information that is on the certificate \( C(p) \) that accompanies an integer \( p \): 1. \( p_0 \): a list of the primes \( p_i \) and the exponents \( a_i \) for the canonical factorization \( p - 1 = \prod_{i=1}^k p_i^{a_i} \). 2. \( C_p \): the certificates \( C(p_i) \) of each of the primes \( p_1, \ldots, p_k \). 3. \( x \): a positive integer \( x \). To verify that \( p \) is prime we could execute the following algorithm \( B \): - (B1) Check that \( p - 1 = \prod_{i=1}^k p_i^{a_i} \). - (B2) Check that each \( p_i \) is prime, using the certificates \( C(p_i) \) \( (i = 1, r) \). - (B3) For each divisor \( d \) of \( p - 1, 1 < d < p - 1 \), check that \( x^d \not\equiv 1 \ (\text{mod } p) \). - (B4) Check that \( x^{p-1} \equiv 1 \ (\text{mod } p) \). This algorithm \( B \) is correct, but it might not operate in polynomial time. In step \( B3 \) we are looking at every divisor of \( p - 1 \), and there may be a lot of them. Fortunately, it isn't necessary to check every divisor of \( p - 1 \). The reader will have no trouble proving that there is a divisor of \( p - 1 \) (\( d < p - 1 \)) for which \( x^d \equiv 1 \ (\text{mod } p) \) if and only if there is such a divisor that has the special form \( d = (p - 1)/r \). The primality checking algorithm \( A \) now reads as follows: - (A1) Check that \( p - 1 = \prod_{i=1}^k p_i^{a_i} \). - (A2) Check that each \( p_i \) is prime, using the certificates \( C(p_i) \) \( (i = 1, r) \). - (A3) For each \( i = 1 \) to \( r \), check that \( x^{(p-1)/p_i} \not\equiv 1 \ (\text{mod } p) \).

How might we convince an audience that a certain integer \( n \) is a prime number? The rules are that we are allowed to do any immense amount of calculation beforehand, and the results of that calculation can be written on a certificate \( C(n) \) that accompanies the integer \( n \). The audience, however, will need to see only a polynomial amount of further computation in order to convince themselves that \( n \) is prime. We will describe a primality-checking algorithm \( A \) with the following properties: 1. If \( n \) is the integer and \( A \) a certain certificate \( C(n) \). 2. If \( n \) is prime then the action of \( A \) on the inputs \( (n, C(n)) \) results in the output `it is prime`. 3. If \( n \) is not prime then for every possible certificate \( C(n) \) the action of \( A \) on the inputs \( (n, C(n)) \) results in the output `primality of \( n \) is not verified`. 4. Algorithm \( A \) runs in polynomial time. Now the question is, does such a procedure exist for primality verification? The answer is affirmative, and we will now describe one. The fact that primality can be quickly verified, if not quickly discovered, is of great importance for the developments of Chapter 5. In the language of section 5.1, what we are about to do is show that the problem “Is \( n \) prime?” belongs to the class NP. The next lemma is a kind of converse to Fermat’s little theorem (theorem 4.5.2). ## Lemma 4.10.1 Let \( p \) be a positive integer. Suppose there is an integer \( x \) such that \( x^{p-1} \equiv 1 \,(\text{mod } p) \) and such that for all divisors of \( p-1 \), \( d < p-1 \), we have \( x^{d} \not\equiv 1 \,(\text{mod } p) \). Then \( p \) is prime. **Proof:** First we claim that \( \gcd(d, x) = 1 \), for \( d = \text{gcd}(p, x) \). Then \( x = g^{r} \) and \( p = g^{s} \). Since \( x^{p-1} \equiv 1 \), it follows that \( x^{p-1} = 1 + t + x^{p-1} - t = (gs)^{p-1} - 1 \). The left side is a multiple of \( g \). The right side is not, unless \( g = 1 \). It follows that \( x \in U_{p} \), the group of units \( Z_{p} \). Thus \( x \) is an element of order \( p - 1 \) in a group of order \( \varphi(p) \). Hence \( \varphi(p) \leq p - 1 \). Hence \( \varphi(p) = p - 1 \) and \( p \) is prime. Lemma 4.10.1 is the basis for V. Pratt’s method of constructing certificates of primality. The construction of the certificate is actually recursive since step 3b allows for certificates of smaller primes. We suppose that the certificate of the prime \( 2 \) is the trivial case, and that it can be verified at no cost. Here is a complete list of the information that is on the certificate \( C(p) \) that accompanies an integer \( p \) whose primality is to be attested to: 1. \( P \): a list of the primes \( p_i \) and the exponents \( a_i \) for the canonical factorization \( p - 1 = \prod_{i=1}^{k} p_i^{a_i} \). 2. \( C_{p} \): the certificates \( C_{p_i} \) of each of the primes \( p_1, \ldots, p_k \). 3. \( x \): a positive integer \( x \). To verify that \( p \) is prime we could execute the following algorithm \( B \): **(B1)** Check that \( p - 1 = \prod_{i=1}^{k} p_i^{a_i} \). **(B2)** Check that each \( p_i \) is prime, using the certificates \( C_{p_i} \) \( (i = 1, r) \). **(B3)** For each divisor \( d \) of \( p - 1 \), \( d < p - 1 \), check that \( x^{d} \not\equiv 1 \,(\text{mod } p) \). **(B4)** Check that \( x^{p-1} \equiv 1 \,(\text{mod } p) \). This algorithm \( B \) is correct, but it might not operate in polynomial time. In step \( B3 \) we are looking at every divisor of \( p - 1 \) and there may be a lot of them. Fortunately, it isn’t necessary to check every divisor of \( p-1 \). The reader will have no trouble proving that there is a divisor of \( p - 1 \) (or \( < d \) such that \( x^{d} \equiv 1 \,(\text{mod } p) \) and only if there is such a divisor that has the special form \( d = (p - 1)/t \). The primality checking algorithm \( A \) now reads as follows: **(A1)** Check that \( p - 1 = \prod_{i=1}^{k} p_i^{a_i} \). **(A2)** Check that each \( p_i \) is prime, using the certificates \( C_{p_i} \) \( (i = 1, r) \). **(A3)** For each \( i = 1 \) to \( k \), check that \( x^{(p-1)/p_i} \not\equiv 1 \,(\text{mod } p) \).

Now let's look at the complexity of algorithm \( A \). We will measure its complexity by the number of times that we have to do a computation of either of the types (a) \( s \equiv \prod_{i} g^{s_i} \) or (b) \( (b) \, s^e \equiv 1 \, (\text{mod} \, p) \). Let \( f(p) \) be that number. Then we have (remembering that the algorithm calls itself \( t \) times) \[ f(p) = 1 + \sum_{i=2}^{r} f(p_i) + r + 1 \tag{4.10.1} \] in which the four terms, as written, correspond to the four steps in the checking algorithm. The sum begins with \( i = 2 \) because the prime 2, which is always a divisor of \( p - 1 \), is 'free.' Now (4.10.1) can be written as \[ g(p) = 1 + f(p). \tag{4.10.2} \] We claim that \( g(p) \leq 4 \log_2 p \) for all \( p \). This is surely true if \( p = 2 \). If true for primes less than \( p \) then from (4.10.2), \[ g(p) \leq \sum_{i=2}^{r} 4 \log_2 p_i + 4 \] \[ = 4 \log_2 \left( \prod_{i=2}^{r} p_i \right) + 4 \] \[ \leq 4 \log_2 \left( \frac{(p-1)}{2} \right) + 4 \] \[ = 4 \log_2 (p - 1) \leq 4 \log_2 p. \] Hence \( f(p) \leq 4 \log_2 p - 1 \) for all \( p \geq 2 \). Since the number of bits in \( p \) is \( \Theta(\log p) \), the number \( f(p) \) is a number of executions of steps that is a polynomial in the length of the input bit string. We leave to the exercises the verification that the steps that \( f(p) \) counts is also executed in polynomial time, so the entire primality-verification procedure operates in polynomial time. This yields **Theorem 4.10.1.** (W. Pratt, 1975) There exists a checking algorithm and a certificate such that primality can be verified in polynomial time. ## Exercises for section 4.10 1. Show that two positive integers of \( b \) bits each can be multiplied with at most \( O(b^2) \) bit operations (multiplications and carries). 2. Prove that step A1 of algorithm \( A \) can be executed in polynomial time, where time is now measured by the number of bit operations that are implied by the integer multiplications. 3. Same as exercise 2 above, for steps 4.3 and A4. 4. Write out the complete certificate that attests to the primality of \( p \). 5. Find an upper bound for the total number of bits that are in the certificate of the integer \( p \). 6. Carry out the complete checking algorithm on the certificate that you prepared in exercise 4 above. 7. Let \( p = 15 \). Show that there is no integer \( x \) as described in the hypotheses of lemma 4.10.1. 8. Let \( p = 17 \). Find all integers \( x \) that satisfy the hypotheses of lemma 4.10.1.

Now let's look at the complexity of algorithm \( A \).
