Abstract

If multicast communication appears as the most efficient way to send data to a group of participants, it presents also more vulnerabilities to attacks and requires services such as authentication, integrity and confidentiality to transport data securely. We present the protocol, Baal, as a scalable solution to group key management problems and show how Baal resolves the user´s revocation problem. This protocol is based on decentralized group key management with only one key shared among group members. We use then Network Simulator ns-2, in order to evaluate the performance of our protocol in the case of group initialization, and compare it with single key distribution center (SKDC) approaches
