1. 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
(d) repeating steps (a) to (c) as required to generate further nonces in the sequence of nonces.

Abstract
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.

10. A device for generating a sequence of nonces (R0, R1, R2, . . . ), the device including:
-
memory for storing a current seed of a sequence of seeds (x1, x2, x3, . . . )’
a processor configured to;
(a) apply a one way function to the current seed to generate a current nonce; and
(b) use the current seed to generate a next seed in the sequence of seeds, the seed so generated becoming the current seed; and
(c) storing the current seed in memory. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
