Problems solved by technology

The utility model adopts quantum encryption, which has a simple structure and cannot be deciphered, which improves the security of the camera image content. The encryption structure realizes the data transmission of the encryption module through the Ethernet during data transmission, but the transmission range of the Ethernet is limited. , so the use of the Internet will inevitably be used when transferring related encryption modules. Third-party interference can realize encryption module data interception or stealing through the Internet, a wide area network. Therefore, a self-destruct and leak-proof structure is required to ensure that the encryption module After the data is intercepted and stolen by a third party, it can be started in time to ensure the confidentiality of the data transmission of the encryption module

Embodiment 1

[0040] The data collection unit can collect and store the video data that needs to be transmitted, and the data copying unit can make multiple copies of the video data in the data collection unit that needs to be encrypted and transmitted.

[0041] Specifically, the video data to be transmitted is stored by the data acquisition unit, which can provide transmission source support for subsequent secondary and multiple transmissions. By duplicating the video data, cracking of the video data can be avoided. Moreover, after the data is cracked and reorganized, the fluency between data fragments is affected, thereby ensuring the integrity and fluency of the decrypted data, and providing conditions for reducing data distortion.

Embodiment 2

[0043] The data noise reduction processing unit uses a filter to process the video data, and the data compression unit can compress the video data processed by the data copying unit one by one.

[0044] In addition, the setting of the data noise reduction processing unit can perform corresponding preprocessing on the data before transmission. The filter can reduce the undue noise of the audio in the video, so as to obtain clear video data, which can reduce the memory size during the subsequent encrypted transmission. After compression processing, the memory size of data transmission is further reduced, so as to ensure the transmission speed of encrypted data.

Embodiment 3

[0046] There are two communication network channels connected between the quantum encryption unit and the judgment unit. When the quantum encryption unit performs encryption processing, the time of encrypting data, the quantity of encryption, and the data after encryption processing can be processed by the quantum encryption unit. Detect the encryption time and encrypted quantity transmitted by the quantum encryption unit as the basis, and check with the received encrypted processed data. If there is a discrepancy between the quantity or the encrypted time, it can be judged that there is a third party in the transmitted data. For interception or stealing, this information needs to be transmitted to the data receiving module through the public communication network channel 3 for secondary encrypted transmission. If both the quantity and the encrypted time are consistent, it means that there is no third-party interception in this encrypted transmission Or the phenomenon of steali...

Description

technical field [0001] The invention relates to the technical field of quantum encryption, in particular to a video monitoring quantum encryption system. Background technique [0002] In traditional encrypted communication channels, the information source is encrypted and then transmitted to the data receiver through the information sender. During this process, third parties such as eavesdroppers can obtain the encrypted information sent by the information sender by intercepting or stealing and copying. The processed data can be deciphered immediately to cause the leakage of encrypted information. In addition, there are keys in both the information sender and the information receiver, so there is a possibility of leakage in the source, process and terminal of information transmission, making the traditional Encrypted communication is less secure, and quantum encryption, as an emerging encryption method, provides provable security and detectability to external interference, t...
