Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] refer to figure 1 , the system adopted by the point-to-point file transmission method based on the quantum key synchronous destruction technology includes a quantum encryption engineering module, a quantum key control hub, and a quantum decryption engineering module.

[0042] The quantum encryption engineering module includes a first quantum key scrambling module, and the first quantum key scrambling module is used to send an acquisition to the first quantum key storage module in the first quantum key control hub according to the size of the original privacy file. The request message of the quantum key corresponding to the size of the original privacy file, and the first quantum key scrambling module generates a pseudo-random password to scramble the received...

Abstract

The invention discloses a point-to-point file transmission method based on the quantum key synchronous destruction technology, which belongs to the field of quantum communication. The user uploads the original privacy file to be encrypted to the quantum encryption engineering module; before the encrypted transmission, the sender and the receiver are checked. Whether the quantum key storage module is synchronized, the synchronization will carry out encrypted transmission, use the quantum key to encrypt in the quantum encryption engineering module, obtain the ciphertext file, and send the ciphertext file to the receiving party's quantum decryption engineering module for decryption, and get the original Privacy document. This method combines quantum communication and a one-time code book that cannot be guessed by violence to form a highly secure communication method.

Description

technical field [0001] The invention relates to the field of quantum communication, in particular to a point-to-point file transmission method based on quantum key synchronous destruction technology. Background technique [0002] Quantum communication refers to a new type of communication method that uses quantum entanglement effect for information transmission. Quantum communication is a new interdisciplinary subject developed in the past two decades, and a new research field combining quantum theory and information theory. Compared with optical quantum communication, the security and efficiency of classical communication cannot be compared with it. At present, this technology has become a research hotspot in quantum physics and information science in the world. my country also launched the first quantum communication satellite in 2015 to conduct quantum communication research. Quantum communication has absolute security characteristics that traditional communication meth...
