Modified Privacy-Preserving Universal Authentication Protocol (MPriAuth) for Security of Mobile IP Networks

摘要

An efficient universal authentication protocol is vital to preserve the users' privacy in mobile networks. Different privacy safeguarding authentication protocols was proposed lately. However the mass of them either have high communication expenses or lacks in privacy protection. In this given paper, propose a Modified Privacy Preserving Universal Authentication Protocol (MPriAuth) aimed at mobile IP networks. It is devised to authenticate the mobile users in foreign network whilst safeguarding the users' privacy. The proposed MPriAuth algorithm has three step; key generation, key sign and key verify. Group signature is utilized for key generation together with key verification. The proposed technique is simulated utilizing the NS3. The outcomes exhibit that the MpriAuth algorithm preserves the users' privacy without trading off the quality of service. Likewise the group signature sharing decreased the computation time; thus the communication cost is lessened.
