Method for encrypting and decrypting information based on quantum network

Abstract

The invention relates to the technical field of the quantum communication, and especially a method for encrypting and decrypting information based on a quantum network. The invention aims at providinga method for encrypting and decrypting the information based on the quantum network, and the method is simple in step and high in safety guarantee; a sender performs encryption through a quantum keyK and edited information M to form information M'K, and then encrypts the quantum key K by using an encryption public key Ka to form a ciphertext key K'Ka, and finally combines the ciphertext key K'Kawith the information M'K to form the information E to send out; a receiver firstly acquires a decryption private key Kb by using a U key, and then performs the identity authentication, and decrypts the encrypted information through the decryption private key Kb when the identity authentication is qualified, thereby guaranteeing that only the personnel successfully passing the identity authentication can decrypt the encrypted information and read the content in the information, and the information security is improved.

Description

technical field [0001] The invention relates to the technical field of quantum communication, in particular to a method for encrypting and decrypting information based on a quantum network. Background technique [0002] With the outbreak of the information revolution in the 21st century and the continuous development of science and technology, how to ensure secure communication between clients is a current research hotspot, to achieve information security such as data encryption, transmission and privacy, whether it is an enterprise that conducts daily business activities Companies, government agencies, banks, etc. all have urgent needs for this, especially in today's globalized economic era, ensuring the unconditional security of information is one of the current focuses of public attention. [0003] At present, enterprises or individuals have used quantum networks to encrypt and decrypt information. Quantum networks include quantum true random number generators, identity a...

Problems solved by technology

[0003] At present, enterprises or individuals have used quantum networks to encrypt and decrypt information. Quantum networks include quantum true random number generators, identity authentication servers, quantum key management servers, and public and private key servers. For example, the existing patent number is 201810020795.0, patent The name is a communication system and communication method based on quantum network to realize information encryption and decryption transmission. The communication system includes a quantum network service station configured on the network side and two clients configured on the user side. Each client is equipped with a quantum key card. When the two clients communicate, they obtain the shared key directly or indirectly through the quantum network service station on the network side; the two clients use the shared key in the corresponding quantum key card to encrypt and decrypt the information for transmission; The encryption and decryption transmission method invented requires the two clients to use the shared key in the quantum key card to encrypt and decrypt the information, so that the encryption and decryption method has the disadvantages of troublesome operation steps and low safety factor
