A method for authenticating mobile multimedia streaming conditional access, mobile multimedia streaming conditional access system, mobile multimedia streaming conditional access front end, and mobile multimedia streaming conditional access terminal.

摘要

method for authentication in conditional access of mobile multimedia transmission, conditional system of mobile multimedia transmission, front end access of conditional access of mobile multimedia transmission and conditional access terminal of mobile multimedia transmission the present invention describes a method and a system for authentication in conditional access for mobile multimedia transmission, and the method comprises the following steps of: performing authentication from the front end to a terminal that requests a private key and, when authentication occurs, said front end groups the private key and sends said private key to said terminal via a bidirectional channel and a unidirectional channel. the system includes an anterior end and a terminal. the present invention performs data transmission in the authentication process through a method of combining the unidirectional channel and the bidirectional channel, thereby increasing the security of information transmission.
