Certificateless-Based Authenticated Group Key Agreement Protocol
摘要
Abstract
An certificaleless-based authenticated group key agreement protocol is proposed based on the property multilinear forms and elliptic curve discrete logarithm problem. The new scheme not only avoids the complex management of certificates in PKJ scheme, but also avoids the key escrow issues inherited in the identity-based schemes effectively and prevents active attack by identity authentication. And then, the correctness of the session key is confirmed by computing, the formal analysis based on applied Pi calculus has shown fulfilled authentication and security. Compared with other authenticated group key agreement protocols,die newly proposed group key agreement protocol has better security with the cost of little computation and more stronger practicality.关键词
