WebIn the first meaning, a "generator" is defined to be an element that generates the entire group. That is, when we talk about DH (and thus the group Z p ∗ ), we say that g generates the entire group means g k mod p can take on any value between 1 and p − 1. In the second meaning, we say that an element g "generates" a subgroup.

"WebWhen a non-cryptographic PRNG is used in a cryptographic context, it can expose the cryptography to certain types of attacks. Often a pseudo-random number generator (PRNG) is not designed for cryptography. Sometimes a mediocre source of randomness is sufficient or preferable for algorithms that use random numbers.

WebA key can directly be generated by using the output of a Random Bit Generator (RBG), a system that generates a sequence of unpredictable and unbiased bits. [10] A RBG can be used to directly produce either a symmetric key or the random output for an asymmetric key pair generation. WebPseudo-Random Number Generators. We want to be able to take a few "true random bits" (seed) and generate more "random looking bits", i.e. construct a function G: { 0, 1 } t → { 0, 1 } T, T ≫ t . The generated bit strings should "look random" to an adversary. In cryptography, PRNG’s are used to construct session keys and stream ciphers.
