Hello,
I would like to find out how the RNG test is organized. The following
statement in nettle/int/drbg-aes.c is puzzling:
At line 147:
/* Throw the first block generated. FIPS 140-2 requirement (see
* the continuous random number generator test in 4.9.2)
*/
if (ctx->prev_block_present == 0) {
INCREMENT(sizeof(ctx->v), ctx->v);
aes_encrypt(&ctx->key, AES_BLOCK_SIZE, ctx->prev_block, ctx->v);
ctx->prev_block_present = 1;
}
What does '4.9.2' mean ?
Thanks.
