Used as the improvement of above-mentioned technical proposal, the work to tuner in step one carries out timing, right in step 3
The work of receiver carries out timing, and control signal is used to control the work of tuner in step 6.
Compared with prior art, implementation result of the invention is as follows for the present invention：
The outdoor unit theft preventing method of satellite television receiving system of the present invention, by satellite television receiving system
Operating time carry out timing, and as the input value of AES, so as to improve the security of AES output valve, when defending
The outdoor unit of star TV receiving system can fail after individually being stolen, it is impossible to the room with other satellite television receiving systems
Interior unit matching work, so as to improve the security of the outdoor unit of satellite television receiving system, realizes antitheft function.
Brief description of the drawings
Fig. 1 is the structural representation of the outdoor unit theft preventing method application apparatus of satellite television receiving system of the present invention
Figure.
Specific embodiment
Illustrate present disclosure below in conjunction with specific embodiments.
As shown in figure 1, being the outdoor unit theft preventing method application apparatus of satellite television receiving system of the present invention
Structural representation.The outdoor unit theft preventing method application apparatus of satellite television receiving system of the present invention, including：For recording
Operating time can be simultaneously converted into the first timer that data signal is exported, first timing by satellite receiving equipment operating time
Device is arranged at the outdoor unit of satellite television receiving system；For receiving the data signal of the first counter output and carrying out
To export the first encrypting module of coded signal, first encrypting module is arranged at satellite television receiving system to computations
Outdoor unit；By recording satellite receiving equipment operating time and operating time can be converted into based on the second of data signal output
When device, second timer is arranged at the indoor unit of satellite television receiving system；It is defeated for receiving second counter
The data signal that goes out simultaneously carries out computations to export the second encrypting module of coded signal, and second encrypting module is arranged at
The indoor unit of satellite television receiving system；For receive first encrypting module and second encrypting module output plus
Secret letter number is simultaneously compared to determine whether the authentication module of output control signal, and the authentication module is arranged at satellite television and connects
The outdoor unit of receipts system；Control signal for receiving the authentication module output makes the open air of satellite television receiving system single
The control module of first normal work, the control module is arranged at the outdoor unit of satellite television receiving system.
Specifically, the control module is arranged in low noise block downconverter and is used to control low noise block downconverter（I.e.
Tuner）In integrated chip operation.
The outdoor unit theft preventing method application apparatus of satellite television receiving system of the present invention is with following method reality
Existing its anti-theft feature：
Step one：The outdoor unit of satellite television receiving system is operated and timing, the family of satellite television receiving system
Microwave signal is received during outer cell operation and intermediate-freuqncy signal is exported；
Step 2：The timing result that step one is obtained is encrypted calculating and obtains the first encryption data；
Step 3：The indoor unit of satellite television receiving system receives the outdoor unit output of satellite television receiving system
Intermediate-freuqncy signal be just operated and timing；
Step 4：By step 3 obtain timing result be encrypted calculating obtain the second encryption data, this step plus
Close algorithm is identical with step 2；
Step 5：The second encryption data that the first encryption data and step 4 obtained to step 2 are obtained is contrasted,
It is output control signal when comparing result is consistent, otherwise not output control signal；
Step 6：The control signal for receiving step 5 output controls the outdoor unit of satellite television receiving system to carry out
Work, otherwise makes the outdoor unit of satellite television receiving system be stopped.
The AES of computations is included but is not limited in above-mentioned steps two and step 4：
DES（Data EncryptionStandard, data encryption standards）AES,
DSA（Digital Signature Algorithm, Digital Signature Algorithm）AES,
AES（Advanced Encryption Standard, Advanced Encryption Standard）AES etc..
Because the work of the indoor unit of the outdoor unit and satellite television receiving system of satellite television receiving system has
Synchronism, therefore the timing result that step one is obtained is the data signal of the first timer output and the meter of step 3 acquisition
When result be second timer output data signal it is identical, as long as in ensureing i.e. described second encrypting module of step 4
AES and step 2 are that the AES in first encrypting module is identical, and the first encryption data is first encryption
The coded signal and the second encryption data of module output are that the coded signal of the second encrypting module output also can be identical, step
Five i.e. the authentication module will output control signal, be operated the outdoor unit of satellite television receiving system.
After the outdoor unit of satellite television receiving system is stolen, due to the outdoor unit of satellite television receiving system
In the first timer timing result and the second timer of the indoor unit of new satellite television receiving system timing knot
It is really inconsistent, therefore by first encrypting module and the coded signal of second encrypting module output and differ,
Authentication module stops output control signal so that the outdoor unit of satellite television receiving system is stopped.
Specifically, because the tuner in the outdoor unit of satellite television receiving system usually contains one or several collection
Into chip, therefore can be integrated in above-mentioned integrated chip by authentication module and control module, connect so as to improve satellite television
The security of the outdoor unit theft preventing method application apparatus of receipts system, destroys the outdoor unit antitheft square of satellite television receiving system
Also tuner can be destroyed while method application apparatus so that the outdoor unit of satellite television receiving system cannot integrally work.
Above content is detailed description made for the present invention in conjunction with specific embodiments, it is impossible to assert that the present invention is specific real
Apply and be only limitted to these explanations.For those skilled in the art, before present inventive concept is not departed from
Put, some simple deduction or replace can also be made, should all be considered as belonging to the scope of protection of the invention.
