A Chebyshev-Map Based One-Way Authentication and Key Agreement Scheme for Multi-Server Environment

One-way authentication and key agreement scheme can achieve strong user anonymity and transmitted data confidentiality over insecure public communication channel, which is very useful for the user who cares about his/her identity information. In conventional networks, Public Key Infrastructure (PKI) is a very useful component to design one-way authentication key agreement scheme. However, it will consume large amounts of computing resources. Therefore, it is inappropriate to PKI in a resource-constrained environment. In this paper, we proposed a new one-way authentication and key agreement scheme based on Chebyshev chaotic map. Compared with the related research activities, our proposed scheme has not only the high efficiency and unique functions, but also robust to various attacks and achieves perfect forward secrecy. Security and performance analyses demonstrate that the proposed scheme can solve various types of security problems and can meet the requirements of computational complexity for low-power mobile devices.
