Efficient mobile dynamic ID authentication and key agreement scheme without trusted servers.

Remote user authentication schemes allow an authorized user to access the resources of remote servers. A dynamic ID authentication scheme further provides the property of user anonymity, that is, information of user identification will not be compromised even if communicated messages are intercepted. When it comes to the mobile user authentication, the client-side processing capability is usually concerned the most. In this paper, the author proposes an efficient mobile dynamic ID authentication and key agreement scheme without trusted servers. For facilitating the application of mobile devices with limited processing capability, our scheme is optimized for the client-side computation. Moreover, compared with related works, the proposed scheme is also more secure. Copyright © 2014 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
