Session Management for Accountability in Distributed Multimedia Services

Internet-based multimedia applications (e.g., voice-over-IP, instant messaging, and video conferencing) are continuing to grow in importance as more people depend on such applications for personal and professional communications. Although performance is almost always a concern with multimedia systems that must satisfy quality-of-service (QoS) constraints, security is also a major requirement given the increasing criticality of such applications. For example, businesses might depend on Internet telephony to reach customers while governments might depend on video streaming to disseminate information. For distributed multimedia services, in addition to the traditional security properties (confidentiality, integrity, and availability), accountability is also important to complement perimeter defenses. Accounting for user actions within the system enables the development of higher-level security services.
