Problems solved by technology
However, due to the time-consuming dial-up of the terminal client and the instability of the radio and television platform server, the process of confirming the user's legitimacy often takes a relatively long time.
[0004] In addition, the existing security scheme only starts the process of checking the user's legitimacy when the terminal is powered on, which leaves a huge loophole for illegal users, such as removing or replacing the terminal while the terminal is powered on (U ) SIM card, etc., resulting in illegal use such as one person paying for multiple people sharing

Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0030] method embodiment
[0031] figure 1 It is a flow chart of an embodiment of the mobile phone TV authentication method of the present invention. Such as figure 1 As shown, the embodiment of the mobile phone TV authentication method of the present invention includes:
[0032] 1. The terminal generates a random number according to the playback request of the current mobile TV
[0033] 2. Send the random number and the service key identifier (MBMSService Key ID, MSKID for short) required by the terminal to play the program to the operator's service platform;
[0034] 3. The operator's service platform searches for the corresponding shared key (KS for short) according to the MSKID of the program requested by the terminal, and according to the MSKID, KS, and the International Mobile Subscriber Identity code of the terminal user identification card (ie (U)SIM ca...

The invention discloses a method, a device and a system for mobile television authentication. The method for mobile television authentication comprises the following steps: a terminal generates random numbers according to current playing requests of a mobile television, sends the random numbers and MSKID (MBMS Service Key ID) in the programs played according to the requirements of the terminal toan operator business platform; the operator business platform searches corresponding KS (Key Sharing) according to the received MSKID, computes SRES (Server Result) according to the random numbers, the MSKID, the KS and IMSI (International Mobile Subscriber Identity) of a terminal user identification card, and sends the SRES to the terminal; the terminal computes RES (Result) according to the IMSI, the MSKID, the KS and the random number, and controls the mobile television playing according to the RES and the received SRES. According to the method, device and system for mobile television authentication, RES and SRES are computed through the terminal and the operator business platform every time a user watches charged programs, a user terminal in the mobile phone television, which requeststhe playing of mobile television, is authenticated by comparing the two values, so that the safety for mobile television playing is improved and the condition that a user pays multiple users for services is avoided.
Description
technical field [0001] The present invention relates to a mobile phone TV authentication method, device and system in particular. Background technique [0002] The prior art does not take into account the handling methods for similar abnormal situations such as removal and replacement of the (U)SIM card after the program is successfully ordered using the (U)SIM card. According to the existing scheme and process, after ordering the program and removing or replacing the (U)SIM card, the user will continue to be able to watch paid programs. [0003] In the current specification of mobile TV, when a user subscribes to a program, the UAM of the terminal will save the program's service key (minimum shift keying, MSK for short), service key identifier (MBMS Service Key ID, MSKID for short) and the calculated The shared key (KS for short, KS is calculated during the GBA initialization process of the mobile phone TV, and stored on the UAM and the operator's business platform respect...
