A method for providing a sequence of nonces (R0, R1, R2, ) commencing with a current seed of a sequence of seeds (x1, x2, x3, . . . ), the method comprising: (a) applying a one-way function to the current seed, thereby to generate a current nonce; (b) outputting the current nonce; (c) using the current seed to generate a next seed in a sequence of seeds, the seed so generated becoming the current seed; and (c) repeating steps (a) to (c) as required to generate further nonces in the sequence of nonces. |
