NEW MODELS AND METHODS FOR ESTIMATING THE CRYPTOGRAPHIC STRENGTH OF INFORMATION SECURITY SYSTEMS

摘要

A new approach to estimating information security of modern information and communication systems is proposed on the basis of the general theory of optimal algorithms. The relation between the quality of information and cryptographic strength of cryptographic and steganographic systems is shown. The choice of the radius of information as the cryptographic work factor is substantiated for various information security systems.
