/*
|
|
* This prime generation algorithm is pretty much cribbed from
|
|
* OpenSSL. The algorithm is:
|
|
*
|
|
* - invent a B-bit random number and ensure the top and bottom
|
|
* bits are set (so it's definitely B-bit, and it's definitely
|
|
* odd)
|
|
*
|
|
* - see if it's coprime to all primes below 2^16; increment it by
|
|
* two until it is (this shouldn't take long in general)
|
|
*
|
|
* - perform the Miller-Rabin primality test enough times to
|
|
* ensure the probability of it being composite is 2^-80 or
|
|
* less
|
|
*
|
|
* - go back to square one if any M-R test fails.
|
|

/*
|
|
* The Miller-Rabin primality test is an extension to the Fermat
|
|
* test. The Fermat test just checks that a^(p-1) == 1 mod p; this
|
|
* is vulnerable to Carmichael numbers. Miller-Rabin considers how
|
|
* that 1 is derived as well.
|
|
*
|
|
* Lemma: if a^2 == 1 (mod p), and p is prime, then either a == 1
|
|
* or a == -1 (mod p).
|
|
*
|
|
* Proof: p divides a^2-1, i.e. p divides (a+1)(a-1). Hence,
|
|
* since p is prime, either p divides (a+1) or p divides (a-1).
|
|
* But this is the same as saying that either a is congruent to
|
|
* -1 mod p or a is congruent to +1 mod p. []
|
|
*
|
|
* Comment: This fails when p is not prime. Consider p=mn, so
|
|
* that mn divides (a+1)(a-1). Now we could have m dividing (a+1)
|
|
* and n dividing (a-1), without the whole of mn dividing either.
|
|
* For example, consider a=10 and p=99. 99 = 9 * 11; 9 divides
|
|
* 10-1 and 11 divides 10+1, so a^2 is congruent to 1 mod p
|
|
* without a having to be congruent to either 1 or -1.
|
|
*
|
|
* So the Miller-Rabin test, as well as considering a^(p-1),
|
|
* considers a^((p-1)/2), a^((p-1)/4), and so on as far as it can
|
|
* go. In other words. we write p-1 as q * 2^k, with k as large as
|
|
* possible (i.e. q must be odd), and we consider the powers
|
|
*
|
|
* a^(q*2^0) a^(q*2^1) ... a^(q*2^(k-1)) a^(q*2^k)
|
|
* i.e. a^((n-1)/2^k) a^((n-1)/2^(k-1)) ... a^((n-1)/2) a^(n-1)
|
|
*
|
|
* If p is to be prime, the last of these must be 1. Therefore, by
|
|
* the above lemma, the one before it must be either 1 or -1. And
|
|
* _if_ it's 1, then the one before that must be either 1 or -1,
|
|
* and so on ... In other words, we expect to see a trailing chain
|
|
* of 1s preceded by a -1. (If we're unlucky, our trailing chain of
|
|
* 1s will be as long as the list so we'll never get to see what
|
|
* lies before it. This doesn't count as a test failure because it
|
|
* hasn't _proved_ that p is not prime.)
|
|
*
|
|
* For example, consider a=2 and p=1729. 1729 is a Carmichael
|
|
* number: although it's not prime, it satisfies a^(p-1) == 1 mod p
|
|
* for any a coprime to it. So the Fermat test wouldn't have a
|
|
* problem with it at all, unless we happened to stumble on an a
|
|
* which had a common factor.
|
|
*
|
|
* So. 1729 - 1 equals 27 * 2^6. So we look at
|
|
*
|
|
* 2^27 mod 1729 == 645
|
|
* 2^108 mod 1729 == 1065
|
|
* 2^216 mod 1729 == 1
|
|
* 2^432 mod 1729 == 1
|
|
* 2^864 mod 1729 == 1
|
|
* 2^1728 mod 1729 == 1
|
|
*
|
|
* We do have a trailing string of 1s, so the Fermat test would
|
|
* have been happy. But this trailing string of 1s is preceded by
|
|
* 1065; whereas if 1729 were prime, we'd expect to see it preceded
|
|
* by -1 (i.e. 1728.). Guards! Seize this impostor.
|
|
*
|
|
* (If we were unlucky, we might have tried a=16 instead of a=2;
|
|
* now 16^27 mod 1729 == 1, so we would have seen a long string of
|
|
* 1s and wouldn't have seen the thing _before_ the 1s. So, just
|
|
* like the Fermat test, for a given p there may well exist values
|
|
* of a which fail to show up its compositeness. So we try several,
|
|
* just like the Fermat test. The difference is that Miller-Rabin
|
|
* is not _in general_ fooled by Carmichael numbers.)
|
|
*
|
|
* Put simply, then, the Miller-Rabin test requires us to:
|
|
*
|
|
* 1. write p-1 as q * 2^k, with q odd
|
|
* 2. compute z = (a^q) mod p.
|
|
* 3. report success if z == 1 or z == -1.
|
|
* 4. square z at most k-1 times, and report success if it becomes
|
|
* -1 at any point.
|
|
* 5. report failure otherwise.
|
|
*
|
|
* (We expect z to become -1 after at most k-1 squarings, because
|
|
* if it became -1 after k squarings then a^(p-1) would fail to be
|
|
* 1. And we don't need to investigate what happens after we see a
|
|
* -1, because we _know_ that -1 squared is 1 modulo anything at
|
|
* all, so after we've seen a -1 we can be sure of seeing nothing
|
|
* but 1s.)
