[0027] In the specific implementation process, by integrating the quantum random number source 2 inside the device, the key for encryption and decryption can be generated in real time, ensuring "one-time pad" and preventing risks to information security due to loss of root key. At the same time, the integration level is improved, and the possibility of data tampering and theft is reduced.
[0028] Embodiment 2
[0029] A quantum random number general encryption security device includes a communication interface module 1, a quantum random number source 2, a data acquisition module 3, and a processing module 4.
[0030] The data acquisition module 3 is bidirectionally connected with the communication interface module 1, the quantum random number source 2, and the processing module 4, respectively.
[0031] More specifically, the communication interface module 1, the quantum random number source 2, the data acquisition module 3, and the processing module 4 are integrated on one circuit board.
[0032] In the specific implementation process, by highly integrating the communication interface module 1 for communication with the outside with the quantum random number source 2, the data acquisition module 3, and the processing module 4, data can be efficiently and stably transmitted.
[0033] More specifically, the processing module 4 includes a processor 41 and a storage unit 42.
[0034] The processor 41 is bidirectionally connected with the data acquisition module 3 and the storage unit 42, respectively.
[0035] More specifically, the storage unit 42 has at least two.
[0036] In the specific implementation process, one of the storage units 42 is used to store encryption and decryption keys.
[0037] More specifically, the storage unit 42 has three.
[0038] In the specific implementation process, the three storage units 42 are respectively used to store encryption and decryption keys, running data of the processor 41, and related configuration information such as start of the processor 41 and start of the data acquisition module 3.
[0039] More specifically, the interface type of the communication interface module 1 is a USB interface.
[0040] More specifically, the communication interface module 1 has only one.
[0041] In the specific implementation process, the communication interface module 1 serves as the external window of the entire device, which is the only channel for the quantum security device to communicate with the outside world, reducing the possibility of data tampering and theft.
[0042] More specifically, the quantum random number source 2 uses a chip that is an optical quantum random number chip.
[0043] More specifically, the data acquisition module 3 is an FPGA module.
[0044] In the specific implementation process, the FPGA module sends a sampling signal to the quantum random number source 2, and the quantum random number source 2 generates a quantum source random number sequence with the same frequency as the sampling signal after receiving the sampling signal; then the FPGA module generates a quantum random number sequence that meets the binary sequence true random number rule according to the quantum source random number sequence. The quantum random number sequence enters the processor 41, the processor 41 performs encryption processing on the quantum random number sequence, generates a corresponding encryption and decryption key pair, and stores part of the key pair in the storage unit (for storing encryption and decryption keys) 42, and the other part of the key pair is transmitted to the FPGA module through the processor 41, and the FPGA module receives the key pair and uploads the key pair to the external data encryption server through the communication interface module 1 for storage.
[0045] When external data enters the quantum security device, the data first communicates with the communication interface module 1 through the USB3.0 interface, and transmits the data to the FPGA module through the communication interface module 1; the FPGA module receives the data, and distinguishes and retains the data marked for encryption and decryption, and eliminates other data without identification, and transmits the processed data to the processor 41. After the processor 41 receives the data, it performs encryption and decryption processing on the data by reading the key pair data in the storage unit (for storing encryption and decryption keys) 42, and transmits the processed data back to the FPGA module, and then transmits it to the external device through the communication interface module 1;
[0046] After completing the encryption and decryption process of the data, the used key will be discarded, and the FPGA module will collect quantum source random number sequences from the quantum random number source 2 again to generate new encryption and decryption keys, ensuring "one-time one-key" to ensure secure numerical control transmission. Since the encryption and decryption of data are carried out in the quantum security device, and the generation of keys also comes from the quantum random number source 2 inside the device, the risk of data leakage is effectively reduced.
[0047] According to the disclosure and teaching of the above description, the skilled in the art of the present application can also change and modify the above embodiments.
