WebIn cryptography, PRNG’s are used to construct session keys and stream ciphers. True Randomness is generated from some source such as thermal noise. Abstractly, a random source defines a distribution on { 0, 1 } n. Example: n -way independent bits b 1,..., b n and Pr [ b i = 1] = p , Pr [ b i = 0] = 1 − p. Example: b 1,..., b n uniform on { 0, 1 } n

WebPseudo-random number generators (PRNGs) are algorithms that can create long runs of numbers with good random properties but eventually the sequence repeats. Thus, the term ‘pseudo’ random number generators. The algorithms essentially generate numbers that, while not being truly random, are random enough for cryptographic applications. WebCryptographic algorithms require keys.
