An Efficient ID-Based Mutual Authentication Secure against Privileged-Insider Attack

摘要

Many people conveniently can use Internet banking, online shopping and e-payment. Those services need low computation load and secure protocol against various attacks for using them in mobile environment. As a result of active research for this topic, Elliptic Curve Cryptography (ECC) is used to reduce computation load and various protocols that are based on Discrete Logarithm Problem (DLP) and Computational Diffie Hellman Problem (CDH) have been presented. But some protocols are vulnerable to privileged-insider attack. This paper introduces an efficient ID-based mutual authentication with key agreement protocol by solving problems of the previous, so it is strong secure against all known attacks, especially privileged-insider attack.
