cryptographic Primitives: Insertions, Examples and Open Problems

Abstract

Cryptographic primitives are considered. Each of cryptographic primitives can be the basis for building more complex cryptographic protocol. Examples of insertion of cryptographic primitives are given. The problems arising at the proof of security of the final protocol and primitives underlying it are being discussed.
