- * Theo de Raadt <[email protected]> came up with the idea of using
- * such a mathematical system to generate more random (yet non-repeating)
- * ids to solve the resolver/named problem. But Niels designed the
- * actual system based on the constraints.

- * seed = random 15bit
- * n = prime, g0 = generator to n,
- * j = random so that gcd(j,n-1) == 1
- * g = g0^j mod n will be a generator again.
- *
- * X[0] = random seed.
- * X[n] = a*X[n-1]+b mod m is a Linear Congruential Generator
- * with a = 7^(even random) mod m,
- * b = random with gcd(b,m) == 1
- * m = 31104 and a maximal period of m-1.
- *
- * The transaction id is determined by:
- * id[n] = seed xor (g^X[n] mod n)
- *
- * Effectively the id is restricted to the lower 15 bits, thus
- * yielding two different cycles by toggling the msb on and off.
- * This avoids reuse issues caused by reseeding.
