Described mini-tuner condition receiving system, it is characterized in that, comprise the Entitlement Control Message that is used to control the scrambling mode in the described scrambling parameter, be used for the Entitlement Management Message of receiver control descrambling authority, the system upgrade information of be used for upgrading descrambling program and parameter one or more.
Described mini-tuner condition receiving system is characterized in that, described scrambling parameter is encrypted to condition data, appends in the scrambled data streams, and receiver solves the scrambling parameter from condition data, descrambling is controlled.
Described mini-tuner condition receiving system, it is characterized in that, according to the Entitlement Control Message that sets in advance or add in real time, the scrambling end can different scrambling modes carry out scrambling to the different The data in the original data stream, according to the Entitlement Control Message that sets in advance or take out from the control data that the scrambling end adds, receiver also can carry out the descrambling reduction with different scrambled data by corresponding different descrambling modes.
Described mini-tuner condition receiving system, it is characterized in that, according to the Entitlement Management Message that sets in advance or add in real time at the receiver of specific authentication numbering, the management data that carries Entitlement Management Message that the scrambling end will be encrypted is inserted in the scrambled data streams, the receiver that only has the respective specific authentication code could be discerned exclusive management data, therefrom take out Entitlement Management Message, adjust the descrambling authority and preserve, allow or forbid specific scrambled data is carried out the descrambling reduction.
Described mini-tuner condition receiving system, it is characterized in that, according to the scrambling parameter that sets in advance, the scrambling end can a scrambling original data stream in specific data, not additional other condition data, same according to the scrambling parameter that writes in advance, receiver can be discerned scrambled data and carry out the descrambling reduction.
Described mini-tuner condition receiving system, it is characterized in that, only some is encrypted to condition data to described scrambling parameter, append in the scrambled data streams, promptly the scrambling parameter of Chuan Songing has incomplete characteristics, after receiver solves incomplete scrambling parameter, can be combined into complete scrambling parameter jointly with inner additional data, described inner additional data be meant receiver from the authentication module enciphered data and/or from before the part of the scrambling parameter that obtains the condition data.
Described mini-tuner condition receiving system, it is characterized in that, scrambling parameter according to real-time adding, the scrambling end can the scrambling original data stream in specific data, and the condition data of carrying the scrambling parameter that will encrypt is inserted in the scrambled data streams, receiver carries the condition data of scrambling parameter by deciphering, takes out and according to the scrambling parameter, scrambled data is carried out the descrambling reduction.
Embodiment
Embodiment 1 (tuner authentication module)
Tuner authentication module of the present invention, it is characterized in that, possess unique authentication code and can encrypt output, possessing data-interface can integrate with the hardware of tuner, when receiver receives data by tuner, can also read the authentication code of encrypting output, receiver can judge whether the data flow of tuner output is carried out the descrambling reduction according to authentication code.Described authentication code can self checking, and promptly the part according to authentication code can calculate another part.
According to the external command requirement, described tuner authentication module is numbered with the encrypted form authentication output at every turn, and can carry out the encrypting read/write of other key parameter according to order request.
Tuner authentication module and receiver utilize internal key, by all different random number and/or dynamic data are at every turn carried out computing, produce one-time pad, one time one parameter, all different at every turn key, all different at every turn parameter produces all different at every turn algorithm and scrambling mode.Described dynamic data is the identifying code of program data or rolling code, because program data possesses dynamic characteristic at any time changing; The identifying code of rolling code is then safer, because rolling code rolls by the specific internal formula, have only special hardware ability to produce synchronously, and the identifying code of rolling code is just verified the correctness of synchronous rolling for the descrambling end.What the outside rolling code that can't obtain actual use is.As long as ensure that hardware security just can't crack.
For the hardware that prevents the tuner authentication module is cracked, chip is provided with the power noise at random in the execution process instruction, prevents from outside to carry out instruction analysis according to power consumption; Chip also is provided with anti-polishing transducer, is polished when chip, sees that light or lead resistance change all can cause the fuse self-destruction when powering on; Chip is provided with to be upset bus and encrypts storage, can't be in static conditions code analysis and data.
