Security Architecture for Peer to Peer Applications
Security issue is one of the research challenges for P2P application. Currently, researches on P2P security issues mainly focus on individual attack, which lacks systematic consideration. So, they are isolated, which cannot answer following questions. Firstly, what kind of P2P system is secure? Secondly, how to design a secure P2P system? Thirdly, how to assess the security of P2P systems? To answer these questions, it needs to study P2P security issue from the perspective of system, to determinate the security requirements of P2P applications and to design security architecture for P2P applications.
