A Multi-function Password Mutual Authentication Key Agreement Scheme with Privacy PreservinggMay 5th, 2014
Abstract. Mutual authentication and key agreement is important for providing secure remote communication in client-server environment. In this paper, the authors show that the latest related schemes proposed by Shen and Du, and Jiang et al. are vulnerable to a strong variant of off-line guessing attack. Then introduce a novel multi-function password authentication key agreement scheme with smart card based on elliptic curve cryptosystem and one-way hash function. It can not only achieve privacy preserving, re- sist the strong variant of off-line guessing attack but also retain most previously proposed merits without timestamp. The functions of this kind of scheme are firstly classified into auxiliary function and essential function. By comparing the properties with other re- lated schemes, our scheme satisfies more functionality features with normal computation and communication cost, and is practical in pervasive and ubiquitous computing environ- ment.
