Development and analysis of attack-resilient three party authenticated key agreement scheme based on chaotic maps for secure communication

The three party authenticated key agreement protocol assists two parties in affirming one another and agreeing on a shared session key with the assistance of a trusted server. Chaos-based cryptography has seen considerable progress due to the sound characteristics of chaotic systems. Nowadays, many researchers are actively working in this direction and have proposed various three party authenticated key agreement protocols based on chaotic maps. In this paper, we analysed the Zheng et al. ’s scheme (IEEE Access 8:66150–66162, 2020, https://doi.org/10.1109/ACCESS.2020.2979251) and found that it is vulnerable to various attacks like verification table theft attack, impersonation attacks and also it does not provide anonymity to users. Zheng et al.’s scheme also has flaw in registration phase and uses timestamps for key freshness. In this article, we proposed a three party chaotic based authenticated key agreement protocol which is secured against aforementioned attacks. Authors are also compared the proposed scheme with other comparable and existing schemes in terms of security features, computation cost, and communication cost. The comparison analysis shows that the proposed scheme has more security features at a lower cost in computing and communication. We have also demonstrated the security of the proposed protocol within the framework of the random oracle model.
