Probabilistic models of cryptographic systems and their applications

Abstract

The article describes the probabilistic model of a cryptosystem, that provides getting different from each other cryptograms in case of multiple encryption of the same source text. The model is realized by the insertion of the initialization vector into the block scheme of the encryption algorithm, that is sent to the recipient encrypted together with the cryptogram of the source text. The article presents a description of several applications built on the base of the hybrid probabilistic model of the system of cryptographic transformations
