[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0027] In view of the problems existing in the prior art, this disclosure provides a quantum encrypted video image processing method, which is applied to a quantum encrypted video image acquisition device. Figure 1 This is a flowchart illustrating a quantum-encrypted video image processing method provided in an embodiment of this disclosure, as shown below. Figure 1 As shown, the specific process of the quantum encryption video image processing method includes: S110. Receive video data and, based on the video data, obtain the quantum random number and initialization vector corresponding to each image group.

[0028] A GOP (Group of Pictures) is a group of consecutive frames in video coding. It starts with an I-frame and includes P-frames and B-frames. Efficient data storage and transmission are achieved through inter-frame compression.

[0029] Specifically, the quantum-encrypted video image acquisition device first receives video data, then determines multiple image groups based on the received video data, and randomly obtains the quantum random number and initialization vector for each image group.

[0030] Specifically, the quantum encrypted video image acquisition device includes a quantum random number chip, which can randomly generate quantum random numbers and initialization vectors. After receiving video data, the quantum encrypted video image acquisition device's quantum random number chip will randomly generate a quantum random number and an initialization vector corresponding to each image group. The quantum random numbers and initialization vectors corresponding to different image groups are different.

[0031] Among them, the Quantum Random Number Chip (QRNG Chip) is the core hardware for generating truly random numbers based on the principles of quantum mechanics. It utilizes the collapse of a quantum superposition state through a semi-transparent mirror to generate a random sequence, detects random fluctuations in the quantum vacuum (such as laser phase noise), and extracts unpredictable data through joint measurements of entangled photon pairs. The quantum physics mechanism ensures that the output is unpredictable and cannot be copied, thus addressing the predictability shortcomings of traditional pseudo-random number algorithms and improving the security of encryption systems. Since each image group corresponds to a different quantum random number, the stream key determined based on the quantum random number and the initialization vector corresponding to the quantum random number is also different. In other words, the stream key corresponding to each image group is different, which ensures the privacy of the encrypted encoded data obtained by encrypting the encoded data of each image group based on the stream key. This effectively improves the confidentiality of information transmission of the quantum encrypted video image acquisition device, avoids the interception and cracking of sensitive information, and is independent of whether the transmission method is wired or wireless.

[0032] As a specific example, the quantum random number and initialization vector corresponding to each generated image group are 128 bits. As for other possible implementations, the number of bytes of the quantum random number and initialization vector corresponding to each generated image group is not specifically limited in this embodiment of the disclosure.

[0033] Furthermore, the quantum random number chip can achieve a gigabits-level random number generation rate per second, meeting the requirements of efficient encryption and enabling each image group to use a different stream key.

[0034] S120. Determine the stream key based on the quantum random number and the initialization vector.

[0035] After determining the quantum random number and initialization vector corresponding to each image group in step S110, the quantum random number and initialization vector are encrypted in blocks based on the block encryption algorithm to obtain the stream key.

[0036] Among these, block cipher algorithms include AES (Advanced Encryption Standard), which is currently the most popular and widely used symmetric-key encryption algorithm in the world. It replaced the original DES (Data Encryption Standard) and became the next-generation encryption standard.

[0037] S130. In response to receiving the public key sent by the platform server, encrypt the quantum random number to obtain an encrypted quantum random number.

[0038] In addition, the quantum encrypted video image acquisition device communicates with the platform server. After receiving the public key sent by the platform server, the quantum encrypted video image acquisition device encrypts the quantum random number based on the public key sent by the platform server to obtain the encrypted quantum random number.

[0039] Because the quantum-encrypted video image acquisition device encrypts the quantum random number corresponding to each image group using the public key sent by the platform server, even if the encrypted quantum random number is intercepted by a third party during information transmission and the public key is decrypted, the encrypted quantum random number cannot be decrypted, thus ensuring the data security of the quantum random number corresponding to each image group during transmission.

[0040] S140. Encode each image group of the video data to obtain encoded data, and encrypt the encoded data based on the stream key to obtain encrypted encoded data.

[0041] In the specific implementation process, each image group of the video data is encoded to obtain encoded data, and the encoded data is encrypted based on the stream key to obtain encrypted encoded data. This includes: encoding each image group of the video data to obtain encoded data; and performing an XOR operation on the stream key and the encoded data to obtain encrypted encoded data.

[0042] Specifically, the encoded data is obtained by encoding the images of each group of images acquired, and then the encoded data is aligned bit by bit with the stream key and XORed to obtain encrypted encoded data.

[0043] Since each image group corresponds to a different quantum random number, the stream key determined based on the quantum random number and the initialization vector corresponding to the quantum random number is also different. In other words, the stream key corresponding to each image group is different, which ensures the privacy of the encrypted encoded data obtained by encrypting the encoded data of each image group based on the stream key. This effectively improves the confidentiality of information transmission of the quantum encrypted video image acquisition device and avoids the interception and cracking of sensitive information.

[0044] S150. Send the initialization vector, encrypted quantum random number, and encrypted encoded data to the platform server.

[0045] After determining the encrypted quantum random number and encrypted encoded data, the initialization vector, encrypted encoded data, and encrypted quantum random number are sent to the platform server.

[0046] It should be noted that the quantum encrypted video image acquisition device transmits the initialization vector, encrypted quantum random number, and encrypted encoded data to the platform server in NAL network transmission unit format via 4G / 5G, WIFI, and other signals in the wireless communication module.

[0047] Because the encrypted encoded data sent by the quantum encryption video image acquisition device is obtained by encrypting the encoded data of each image group based on the stream key, and the stream key is generated based on quantum random numbers and initialization vectors, the quantum random numbers are randomly generated based on quantum random number chips, and the quantum random numbers corresponding to each image group are different, ensuring that the stream key corresponding to each image group is different. The stream key is generated based on high-level encryption algorithms, which has a certain degree of security.

[0048] Furthermore, the encrypted quantum random numbers sent by the quantum encrypted video image acquisition device are encrypted based on the public key of the platform server. Even if the public key is decrypted during the process of the quantum encrypted video image acquisition device sending the encrypted quantum random numbers to the platform server, the encrypted quantum random numbers cannot be decrypted, thus ensuring the data security of the quantum random numbers corresponding to each image group during the transmission process.

[0049] The quantum-encrypted video image processing method provided in this disclosure first receives video data and, based on the video data, obtains a quantum random number and an initialization vector corresponding to each image group. Then, based on the quantum random number and the initialization vector, a stream key is determined. In response to receiving a public key from a platform server, the quantum random number is encrypted to obtain an encrypted quantum random number. Next, each image group of the video data is encoded to obtain encoded data, and the encoded data is encrypted based on the stream key to obtain encrypted encoded data. Finally, the initialization vector, the encrypted quantum random number, and the encrypted encoded data are sent to the platform server. Since the encrypted encoded data sent by the quantum-encrypted video image acquisition device is obtained by encrypting the encoded data of each image group based on the stream key, and the stream key is generated based on the quantum random number and the initialization vector, and the quantum random number is randomly generated based on a quantum random number chip, the quantum random number corresponding to each image group is different, ensuring that the stream key corresponding to each image group is different. The stream key is generated based on a high-level encryption algorithm, providing a certain level of security. Furthermore, the encrypted quantum random numbers sent by the quantum encrypted video image acquisition device are encrypted based on the public key of the platform server. Even if the public key is decrypted during the process of the quantum encrypted video image acquisition device sending the encrypted quantum random numbers to the platform server, the encrypted quantum random numbers cannot be decrypted, thus ensuring the data security of the quantum random numbers corresponding to each image group during the transmission process.

[0050] Based on the above embodiments, Figure 2 This is another quantum-encrypted video image processing method provided in this disclosure embodiment. The quantum-encrypted video image processing method provided in this disclosure embodiment is applied to a platform server, and the platform server receives... Figure 1 In the corresponding embodiment, the initialization vector, encrypted quantum random number, and encrypted encoded data sent by the quantum encrypted video image acquisition device are as follows: Figure 2As shown, the quantum-encrypted video image processing method includes: S210: Receive the initialization vector, encrypted quantum random number and encrypted encoded data sent by the quantum encrypted video image acquisition device, and determine the quantum random number and stream key based on the initialization vector, encrypted quantum random number and encrypted encoded data.

[0051] In the specific implementation, the quantum random number and stream key are determined based on the initialization vector, the encrypted quantum random number, and the encrypted encoded data. This includes: decrypting the encrypted quantum random number using the platform server's private key to obtain the quantum random number; and determining the stream key based on the quantum random number and the initialization vector.

[0052] The platform server first reads the encrypted quantum random number and initialization vector from the secure dataset. Then, it decrypts the encrypted quantum random number based on the platform server's private key to obtain the quantum random number. Subsequently, based on the quantum random number and initialization vector, it determines the stream key. That is, based on the block cipher algorithm, it processes the quantum random number and initialization vector to obtain the stream key.

[0053] S220. Based on the stream key and the encrypted encoding data, determine the encoded data corresponding to each image group of the video data.

[0054] After determining the stream key in step S210, the encoded data corresponding to each image group of the video data can be decoded by XORing the stream key and the encrypted encoded data. The encoded data corresponding to the decrypted video data can be played normally on the platform server.

[0055] The quantum-encrypted video image processing method provided in this disclosure, after receiving the initialization vector, encrypted quantum random number, and encrypted encoded data sent by the quantum-encrypted video image acquisition device, first determines the quantum random number and stream key based on the initialization vector, encrypted quantum random number, and encrypted encoded data; then, based on the stream key and encrypted encoded data, determines the encoded data corresponding to each image group of the video data. This enables the decryption of the encrypted encoded data on the platform server, resulting in the obtained video data.

[0056] Based on the above embodiments, this disclosure also provides a quantum-encrypted video image acquisition device. Figure 3 This is a schematic diagram of the structure of a quantum-encrypted video image acquisition device provided in an embodiment of this disclosure, as shown below.

[0057] The quantum-encrypted video image acquisition device provided in this embodiment first receives video data and, based on the video data, obtains the quantum random number and initialization vector corresponding to each image group. Then, it determines the stream key based on the quantum random number and initialization vector. In response to receiving the public key sent by the platform server, it encrypts the quantum random number to obtain an encrypted quantum random number. Next, it encodes each image group of the video data to obtain encoded data, and encrypts the encoded data based on the stream key to obtain encrypted encoded data. Finally, it sends the initialization vector, encrypted quantum random number, and encrypted encoded data to the platform server. Since the encrypted encoded data sent by the quantum-encrypted video image acquisition device is obtained by encrypting the encoded data of each image group based on the stream key, and the stream key is generated based on the quantum random number and initialization vector, and the quantum random number is randomly generated based on a quantum random number chip, the quantum random number corresponding to each image group is different, ensuring that the stream key corresponding to each image group is different. The stream key is generated based on a high-level encryption algorithm, providing a certain level of security. Furthermore, the encrypted quantum random numbers sent by the quantum encrypted video image acquisition device are encrypted based on the public key of the platform server. Even if the public key is decrypted during the process of the quantum encrypted video image acquisition device sending the encrypted quantum random numbers to the platform server, the encrypted quantum random numbers cannot be decrypted, thus ensuring the data security of the quantum random numbers corresponding to each image group during the transmission process.

[0058] In a specific implementation, determining the stream key based on the quantum random number and the initialization vector includes: Based on the block cipher algorithm, the quantum random number and initialization vector are processed to obtain the stream key.

[0059] In a specific implementation, encoding each image group of the video data to obtain encoded data, and encrypting the encoded data based on the stream key to obtain encrypted encoded data, includes: Encode each group of images in the video data to obtain encoded data; Based on the stream key and the encoded data, an XOR operation is performed on the stream key and the encoded data to obtain encrypted encoded data.

[0060] Based on the above embodiments, this disclosure also provides a platform server.

Figure 4 As shown, the platform server includes: an information processing module and an encoded data determination module; The information processing module 410 is configured to receive the initialization vector, encrypted quantum random number and encrypted encoded data sent by the quantum encrypted video image acquisition device, and determine the quantum random number and stream key based on the initialization vector, encrypted quantum random number and encrypted encoded data; The encoding data determination module 420 is configured to determine the encoding data corresponding to each image group of the video data based on the stream key and the encrypted encoding data.

[0061] The platform server provided in this embodiment, after receiving the initialization vector, encrypted quantum random number, and encrypted encoded data sent by the quantum encrypted video image acquisition device, first determines the quantum random number and stream key based on the initialization vector, encrypted quantum random number, and encrypted encoded data; then, based on the stream key and encrypted encoded data, it determines the encoded data corresponding to each image group of the video data. This enables the platform server to decrypt the encrypted encoded data, obtaining the final video data.
