Elliptic Curve Cryptography in Securing Networks by Mobile Authentication

Free registration required

Executive Summary

In this paper, the authors propose an enhanced authentication model, which is suitable for low-power mobile devices. It uses an Extended Password Key Exchange Protocols and elliptic-curve-cryptosystem based trust delegation mechanism to generate a delegation pass code for mobile station authentication, and it can effectively defend all known attacks to mobile networks including the denial-of-service attack. Moreover, the mobile station only needs to receive one message and send one message to authenticate itself to a visitor's location register, and the model only requires a single elliptic-curve scalar point multiplication on a mobile device.
