An Efficient ECDSA Authentication Scheme for Mobile IP Networks

Abstract

Translate Article

The use of portable computing devices has been booming in recent years. Making Sure of the security in mobile systems has become a very important issue. However, a Mobile IP has to deal with some crucial problematic situations such as two Mobile Hosts communicating with each other while moving to the same visited network, for the datagram must pass through Foreign Agent. In this article, we shall propose a link-layer routing between two Mobile Hosts to make it possible for Mobile Hosts to communicate with each other directly. And we shall also employ the elliptic curve digital signature algorithm (ECDSA) to achieve authentication and to ensure security.
