摘要：In order to organize informational security the juridical documents, technical means and cryptographically algorithms, systematic, apparatus-systematic or apparatus-technical means are widely used. And with the advent of high-speed digital lines of information transfer requirements for cryptographic means of enciphering is growing more and more. In cryptosystem based on stream ciphers the entering information is not late in cryptosystem and it allows developing high-speed cryptographic hardware. Besides generated pseudo-casual and truly casual sequences it is widely used in cryptosystems for generation of initial values of confidential parameters and the secret key in the electronic digital signature. The idea of working out of algorithm EDC was developed using operations of algebra parameters. Mathematical model of the digital signature, including parts of formation and the signature check, satisfying to conditions of demanded firmness in a composition of algorithm of enciphering and existing complexities of calculations are developed. In this article also methods of estimation crypto stability of stream cipher algorithm of enciphering and practical results of an estimation of the new developed algorithm are resulted. Also the criteria of protection documentary, vocal and information video in information-communication systems and using cryptographic means are given in this article.
