CATV security architecture

The areas of television, telecommunication, and information technology are converging, new application areas are arising and new services are being established. Aside from the traditional delivery channels, computer networks play an increasing role in providing the new services. An important part of these services is based on video. However, in order to develop and establish such services, the differences between traditional video and multimedia applications as well as the requirements, limitations and possibilities for an integration use of both have to be understood. The CATV (cable television) security architecture provides a general description of security services and related mechanisms, and discusses their interrelationships. It also shows how the security services map onto a given network architecture, and briefly discusses their appropriate placement within the OSI/RM. In this paper, we introduce and overview the security services that are enumerated in the CATV security architecture, corresponding security mechanisms, and security management.
