Cryptographic pseudo random number generator

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 WebIf you generate a truly random series of numbers to use as the encryption key, then you need to send the entire series to you recipient. Also, you cannot simply send it as is or the …
