Abstract


The paper considers the design of two-step zero-knowledge protocols of two different types: 1) protocols based on the public encryption 2) protocols based on the public key agreement scheme. The novelty of the proposed design relating to the first type of protocols consists in using specified labels that are embedded in the encrypted message. Due to using the labels the proposed design is free of using hash-functions and provides higher performance and cheaper hardware implementation. The paper describes protocols implemented with using El-Gamal, Rabin, and RSA public-encryption algorithms. There are discussed details of the protocol design, which depends on the used public-encryption algorithm. The novelty of the proposed design relating to the second-type protocols consists in using the public key agreement scheme.

Author Keywords: cryptographic protocol, authentication, public key, secret key, public encryption, discrete logarithm problem, factorization problem.
