Background technology
Common digital video transmission system generally constitutes (as shown in Figure 1) by acquisition front end and Surveillance center at present; Wherein, Acquisition front end partly is made up of video signal collective device (video camera, camera etc.), digital video coding module, transmission equipment, memory etc., and Surveillance center partly is made up of memory, transmission equipment, control terminal, decoding digital video module, display etc.
In said digital video monitor system, said video signal collective device is responsible for converting monitored object to vision signal.Said digital video coding module is in order to convert vision signal to the video data stream that can transmit through circuit or network.Said web-transporting device with or network constitute a data transmission channel that is communicated with acquisition front end and Surveillance center; Said memory is in order to be responsible for the vision signal that storage of collected arrives; Said decoding digital video module is responsible for converting the video data stream that receives to can be accepted by regular display vision signal; And said display is responsible for showing the vision signal of recovering out through decoder; Said control terminal then is in order to said process is controlled.Through this said digital video monitor system, the monitor staff can monitor one or more monitored object in Surveillance center in real time, and can the content of being monitored be stored through memory, as the resource or the authority of later retrieval or verification.
Its simple structure of video monitoring system although it is so, with low cost and obtained extensive application, and cracking that some are heavy, bringing into play important effect in the megacase process.But be to use such system; It is carrying out but existing tangible potential safety hazard when vedio data transmits; Reason is that through the video data that the digital video coding module coding is crossed be the data (promptly expressly) of not taking any encipherment protection; As long as anyone is ready, but just all the very low cost of only use expense can intercept and capture and watch picture material easily.Therefore, monitored object is important, special when institute, or vedio data need through public network (especially through wireless channel>when transmitting, the loss that this potential safety hazard possibly cause will be very huge.In addition, because the existing above-mentioned defective of this said ordinary video supervisory control system makes the range of application of video monitoring receive very big restriction.In order to guarantee that sensitive information is not stolen; Some system cheap, ubiquitous public network of abandonment cost (like internet, public's wireless network etc.) of having to; And the very high VPN network of self-built video private network or lease cost; Construction and use cost that this has increased system undoubtedly greatly have a strong impact on giving full play to of video monitoring system effect.
The utility model content
The technical problem that the utility model will solve provides a kind ofly can carry out real-time encryptedly to video code flow, reduces the risk that sensitive information leaks or is stolen, simultaneously compared with the comparatively cost-effective again video transmission encryption system of VPN network.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of video transmission encryption system comprises acquisition front end and Surveillance center, and acquisition front end comprises video signal collective device, digital video coding encrypting module, transmission equipment, the memory that links to each other successively; Surveillance center comprises memory, transmission equipment, decoding digital video deciphering module, the display that connects successively, and the transmission equipment at Surveillance center place also is connected with control terminal; Communication connects between above-mentioned two transmission equipments; Said digital video coding encrypting module comprises analog video input interface module, digital video coding module, computations module, the Network Interface Module that links to each other successively; Said decoding digital video deciphering module comprises Network Interface Module, deciphering computing module, decoding digital video module, the digital video output interface that links to each other successively; Wherein computations module, deciphering computing module all are to call the computing module that aes algorithm carries out respective encrypted or decryption oprerations, and said computing module also is connected with and is used to preserve aes algorithm and carries out the safety chip that aes algorithm calculates.
Adopt the utility model video transmission encryption system, have following technique effect:
Said digital video coding encrypting module with real-time encrypted function is to have increased a computations module in the ordinary numbers video encoder in the prior art; This computations module is connected with the safety chip of an embedded aes algorithm; Can be before video data stream be sent to Network Interface Module; It is carried out real-time aes algorithm computations; Make the ordinary numbers video encoder have real-time encrypted function, form the digital video coding encrypting module that has AES algorithm for encryption function in the utility model digital video bit stream.Said safety chip is connected with said computing module, can directly call this safety chip when calculating at computing module video data stream is encrypted or deciphered;
Said analog video input interface module receives the analog video signal from video camera or the transmission of other video equipment; Convert this analog video signal to digital video data stream, and should pass to said digital video coding module by said digital video data stream;
Said digital video coding module converts thereof into the compressed encoding digital video data stream after receiving this digital video data stream; Said computations module is carried out real-time encrypted calculating to the compressed encoding digital video data stream from said digital video coding module, so that this compressed encoding digital video data stream finally is enciphered video data stream when Network Interface Module is exported;
The employed AES algorithm of said computations module is preserved by said safety chip, and the aes algorithm calculating process is also accomplished by said safety chip.
Though said decoding digital video deciphering module and digital video coding encrypting module signal flow are to different, its operation principle is basic identical, does not sew at this and states.
Compare prior art; Through the utlity model has real-time encrypted function; When watching enciphered video data stream picture content if desired, then must use identical key and identical algorithm to decipher, so greatly improved difficulty and the cost of stealing video data content to encrypting bitstream; Effectively prevented the risk that the sensitive video frequency image information is leaked or is stolen when transmitting through network, the fail safe that has improved video image information.
Further, also comprise web page server, said two transmission equipments are through realizing the transmission of video data with the wireless connections of said web page server.
Uncertainty for further limiting network transmission; Can adopt the storage facilities of web page server, network security protocol such as SSH, PKI, SET can be set on the other hand, TLS waits and avoids " go-between " to attack between server and transmission equipment and the control terminal as a relaying.
