A New Authentication Model Based on CL-PKC in Resource Limited P2P Systems

This paper proposes a new authentication model based on CL-PKC technology (certificateless public key cryptography) in peer-to-peer systems. With the progress in peer-to-peer technology, lots of things related to the security problems of peer-to-peer systems have been exposing. To solve these security problems, authentication must be settled firstly. So this paper develops an authentication method based on CL-PKC technology, considering the dynamic properties of hybrid peer-to-peer systems. This method simplifies the procedure of getting public keys and authentication procedure, so the efficiency is increased, and the mount of bandwidth required is lower. This method is very fit to the systems with limited resources.
