Abstract

Smart TV broadcasting system is an extensively deployed application which charges users based on their subscription. In Smart TV broadcasting service environments, services providers charge subscription fee by scrambling the programs in CAS. This technique abstain unauthorized televiewers to watch and receive the program. Smart TV malware presents significant threat to Homeland Security. Security for contents running on smart TV terminals is important. As a new smart TV operating system, SMART TV OS offers great flexibility not only for users but also for application developers. However, this flexibility exposes users to additional security threats. This is particularly dangerous for finance and healthcare applications which require high security for sensitive information and transactions. In this paper, we present the security mechanism of DCAS and the technology realization in SMART TV OS, a complete content protection system from headend to terminal. It has all managements and authorization control functions of traditional CA, supporting DCAS terminal and traditional CA simultaneously.
