Abstract:
Digital convergence is introducing more diverse digital television services. The return channel, which enables interactive television, is a key to this development and may be considered the most vulnerable element of the terminal device in terms of information security. Accordingly, its protection from threats brought about by Internet use, such as malicious programs, is of the essence. Multimedia Home Platform (MHP) is one of the most important technologies enabling interactive television. The information security threats related to it are examined from the viewpoint of the service developer. Threat analysis presented in this paper is carried out in Finnish companies that include digital-TV broadcasters, MHP-platform developers, service developers and telecom operators.
