The traditional authentication methods are either based on IPTV basic services or lower-level security value-added services
taking a simple password for authentication
which is not conducive to other application with higher security requirements such as online securities. For this issue
a mechanism of authentication based on set-top boxes is presented
which is oriented to IPTV value-added services requiring high-level security. By exchanging information between the terminal middleware and platform middleware
it can enhance the security of transmitting information effectively
and make a good foundation for the development of services mentioned above.
