Authenticated commutator key agreement protocol

Research output: Contribution to journalArticlepeer-review

Abstract

The original commutator key agreement (CKA) protocol is a two party anonymous key agreement protocol invented by I. Anshel, M. Anshel and D. Goldfeld. In this paper we propose a modification of the CKA protocol with mutual authentication without introducing any additional computational assumptions. In addition, we propose a new zero-knowledge Feige-Fiat-Shamir-type authentication protocol.
