An Identity based Node Authentication and Session Key Management Algorithm using Elliptic Curve Cryptography

The importance of Elliptic Curve Cryptography (ECC) has been increasing rapidly because of its smaller key size compare to other known public-key algorithms. Several user authentication and key management algorithms have been developed so far but most of them contain complex computation. Not only that, most of the schemes rely on remote server for node authentication as well as node communication. In this paper, an ECC based algorithm has been proposed to overcome these kinds of problems. The proposed work will do mutual authentication and session key management for node communication efficiently without putting extra burden on any server but with lesser computation to save the valuable time.
