Authenticated Group Key Agreement with Admission Control

WEN Hai-long, GU Da-wu(School of Information Security Eng., Shanghai Jiaotong Univ., Shanghai 200030, China)  
An authenticated group key agreement scheme with admission control for dynamic peer groups was presented. The scheme uses secret sharing to achieve the integration of admission control and key agreement which can provide the practicability for key agreement scheme. Identity-based cryptosystems are used for mutual authentication and key agreement among group members, and it avoids the bandwidth consuming and expensive computation arising from certificates in PKI. So the scheme can achieve higher security and efficiency.
