A New Key Management Scheme for Strcutrued P2P Systems

Key management is the key for any network system security. And it is the foundation for P2P system to achieve other security mechanisms. Current researches on key management for distributed structured P2P systems show some problems, such as complicate certificates management, key escrow, depending on the trusted third party, and so on. Based secret sharing without relier and certificate less cryptography without paring, this paper designs a new key management scheme for structured P2P systems, which avoids the above problems. Analysis shows that this scheme is stronger secure, efficient and scalable.
