Abstract

The invention provides a method to realize the key security inosculating mobile multimedia broadcasting system that includes: (a) the generation and storage of the broadcasting system network, and refresh the key of program, the generation of mobile communication system network, storage and refresh the business key, and the business key and label are transmitted to the user terminal by the mobile communication system network; (b) the program key is transmitted to the business platform of mobile communication system network by the broadcasting system network, the key is secreted by the business platform, and the secreted control information is returned; (c) the scrambler of broadcasting system network uses the program flow corresponding to the encrypted code, the program flow and the cipher key information are sent by the radio; (d) the user terminal receives the program flow and secreted control information to find the corresponding business key label, and the business key is the parameter, decipher the key of program flow, and decipher the program flow data using the obtained key of program flow.

Description

technical field [0001] The invention relates to mobile network communication and mobile multimedia broadcasting technology. In particular, it relates to a method and a system for providing key security for a user terminal under the condition that a mobile multimedia broadcasting system network and a plurality of mobile communication system networks are merged. Background technique [0002] As people's demand for mobile communication continues to grow, a large number of multimedia services have emerged with the development of the times. Among them, some applications require multiple users to receive the same media data at the same time, such as video-on-demand, TV broadcasting, etc., such as mobile TV services typically. [0003] The simple mobile multimedia broadcasting system MMB network realizes services such as mobile multimedia broadcasting or mobile TV (frequency addressing broadcasting network systems such as DMB, DAB, DVB, etc., which are collectively shown by MMB), ...
