TGKAM: Adaptive Middleware Architecture for Secure Group Communication

Existing group communication middleware may violate security requirements of an application, because it does not harness knowledge of application parameters. These parameters such as arrival rate, departure rate, staying period, group life time and tolerance times for join and leave, are critical for meeting security requirements of the application and for optimizing performance. In this paper, we propose an adaptive middleware architecture for secure group communication which is configurable and tunable. This architecture makes use of tunable group key agreement protocol and application class awareness concept. Experiments performed show that it achieves adaptation with reasonable performance.
