Abstract

Digital computers are deterministic, that is, for every input n, they will produce output x. Cryptographic systems use complex math to encrypt data using non-deterministically generated random keys, or pseudorandom keys, which are statistically indistinguishable from a random sample.  Protecting data and ensuring integrity are core principals of information security. How essential is the use of secure cryptographic ciphers and truly random keys to modern cryptographic security?
