Abstract

The invention provides a quantum communication encryption system for realizing mobile communication quantum encryption transmission and an application method thereof. The quantum communication encryption system comprises a quantum communication network,a quantum key charging machine and quantum key distribution equipment arranged at the quantum key charging machine end, quantum encryption equipment arranged at the service platform end, a quantum security service platform, quantum key distribution equipment arranged at the service platform end, and a quantum terminal encryption module arrangedon the mobile terminal. According to the method, the existing encryption system and process of mobile communication are not changed, the link of information transmission link encryption is not increased, the security of the working key is enhanced, the security of the working key is enhanced and improved by fusing the key distributed by the public and private key system and the key distributed bythe quantum communication technology, and the quantum computing resistance is achieved.

Description

technical field [0001] The invention relates to the field of mobile communication security, in particular to a quantum communication encryption system and a method for realizing mobile communication quantum encryption transmission. Background technique [0002] At present, the link encryption measures for mobile users to the service center through the Internet are mainly based on public-private key system and symmetric key combination system for transmission encryption. [0003] The public-private key system is combined with the symmetric key, the link encryption adopts the symmetric encryption method, and the working key is distributed on the public network through the public-private key system. The central site and each mobile terminal share a pair of public and private keys. The central site generates a working key, encrypts the working key with the public key, and sends it to the mobile terminal. The mobile terminal decrypts it with the paired private key to obtain Work...
