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.
