Cryptographic primitive

A cryptographic primitive is a simple block encryption, is used in evidence. The primitives are assumed in this case was used to frame properties of more complex cryptographic systems to prove or disprove.

Cryptographic primitives are, for example, block ciphers, cryptographically secure hash functions, stream ciphers and cryptographically secure random number generators.

Due to security reductions can be proved in a particular case that a cryptographic system / method, which is composed of these cryptographic primitives, precisely then is "safe" if the underlying primitives are secure.
