Modification of Diffie–Hellman key exchange algorithm for zero knowledge proof

Abstract EN

Networks and entity groupings requires 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.

This paper discusses zero-knowledge protocols and Diffie-Hellman algorithm and analyzes their vulnerability against known attacks.

Also it presents a proposed protocol based on modification of Diffie–Hellman algorithm into an interactive zero-knowledge proof protocol.

The proposed protocol is designed and developed to satisfy the zero-knowledge proof properties and resists the known attacks.
