ANSI X9.31: the purpose of the date/time vector in the PRNG? I known one requirement for prng is, that it's must be for an adversary impossible to detect that a prng is used to create random numbers. If the adversary is able to detect a cycle no matter if short or long he knows that a prng is used. But if he is not able to detect a cycle than he can not distinguish if a prng or a truer rng is used. |

Using an RSA private key simultanously as an AES encryption key to generate random numbers? The RSA private key is generated on external device the reason is obviously: no true PRNG on my embedded device. |
