Abstract

There are networks and entity groupings that require entity authentication while preserving the privacy of the entity being authenticated. Zero-knowledge proof (ZKP) plays an important role in authentication without revealing secret information. Diffie-Hellman (D-H) key exchange algorithm was developed to exchange secret keys through unprotected channels. In this paper D-H algorithm has been modified into an interactive zero-knowledge proof protocol. The proposed protocol is designed to satisfy the zero-knowledge proof properties and resists the known attacks.
