Key exchange process of PIM-SM-based for Multiple Group Communication in P2P

Abstract

Recently, as the P2P service environment repeats evolution, its usage in mobile is rapidly increasing. Applications are being developed in various mobile environments. However, there are still a lot of vulnerability in security service. It needs to guarantee important security elements including authentication and confidentiality between users, that is, between sender and receiver. In this study, I analyzed security service for secure multiple communication in P2P, and proposed key exchange process that provides PIM-SM-based authentication and confidentiality to security join multiple communication service in P2P. I could attempt more specific encryption by using public key in all encryption procedures, but I used public key crypto system only in the initial process for group join, because it needs complicated key distribution and a massive amount of key database construction. The proposed key exchange process is applied to execution of P2P service and shows security for authentication and confidentiality. In the future, it is needed to develop secure access platform to which key exchange process, proposed as the subject of study, is applied.
