Zero-Knowledge Identification Method Based on Block Ciphers

This paper proposes a method for the rapid identification of remote users that implements the cryptographic concept of zero knowledge strict identification. In contrast to existing methods that implementing this principle and are based on modular arithmetic, the proposed solution is based on the use of standard block ciphers. This solution may significantly accelerate the process of strict user identification. Existing zero - knowledge user identification techniques are revised. The proposed procedure for user registration and for the execution of a round of identification. Theoretical and experimental evaluation of the effectiveness have demonstrated that the proposed method achieves an acceleration of the identification process by two orders of magnitude, compared to existing schemes.
