Mutual authentication for wireless communication using elliptic curve digital signature based on pre-known password

Abstract

The appearance of public access wireless networks enables ever-present Internet services, whereas it inducing more challenges of security due to open air mediums. As one of the most widely used security mechanisms, authentication is provide for secure communications by preventing unauthorized usage and negotiating credentials for verification. In the intervening time, it generates heavy overhead and delay to communications, further deteriorating overall system performance. First, a system model based on challenge/response authentication mechanism by using the elliptic curve cryptographic digital signature is introduced, which is wide applied in wireless environment to reduce the computational cost, communication bandwidth and the server overload . Then, the concept of security levels is proposed to describe the protection of communications with regard to the nature of security. © 2012 Springer-Verlag.
