Hierarchical tree approach to group key management using the group Diffie-Hellman protocol Au, Peter King Pong

Abstract

As a result of the increasing popularity of group-oriented peer-to-peer applications, there is an increasing demand for security services in this kind of environment. Key management plays an important foundation role in security services. Quite a few key management solutions have been proposed for peer groups. However, they usually have limited scalability. This paper considers the scalability of a group-oriented environment and proposes a group hierarchy solution to resolve the problem.
