An ID-based mutual authentication with key agreement protocol for multiserver environment on elliptic curve cryptosystem

Mutual authentication is used to validate the legitimacy of a remote login user and a server. Conventional user authentication protocols are suited to solve the privacy and security problems for the single client/server architecture environment. However, the use of computer networks and information technology has grown spectacularly. More and more network architectures are used in multi-server environments. Recently, several authentication schemes for multi-server environments have been proposed. However, the performance of these schemes is not suitable for applications. To improve the performance, we propose a new ID-based mutual authentication protocols for multi-server environment without bilinear pairings. We also show that the proposed scheme is provable secure in the random oracle model. Copyright (C) 2012 John Wiley & Sons, Ltd.
