A New Hybrid Authentication Protocol to Secure Data Communications in Mobile Networks

摘要

The growing area of lightweight devices, such as mobile cell phones, PDA conduct to the rapid growth of mobile networks, they are playing important role in everyone's day. Mobile Networks offer unrestricted mobility and tender important services like M-business, M-Learning, where, such services need to keep security of data as a top concern. The root cause behind the eavesdroppers in these networks is the un-authentication. Designing authentication protocol for mobile networks is a challenging task, because, mobile device's memory, processing power, bandwidths are limited and constrained. Cryptography is the important technique to identify the authenticity in mobile networks. The authentication schemes for this networks use symmetric or asymmetric mechanisms. In this paper, we propose a hybrid authentication protocol that is based on Elliptic Curve Cryptography which is, actually, the suitable technique for mobile devices because of its small key size and high security.
