Authenticated group key agreement with admission control
Hailong Wen, Dawu Gu · 2004
In this paper we present an authenticated group key agreement scheme with admission control for dynamic peer groups. Admission control is a necessary part of group communication. The scheme uses secret sharing to achieve integration of admission control and key agreement and addresses the pre-requisite for key management. Identity-based cryptosystems are used for mutual authentication and key agreement, and it avoids bandwidth consuming and expensive computation arising from certificates in PKI.
