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 WebCryptographic algorithms require keys.
