End-to-end encryption method and system based on mobile network and communication client side

Abstract

The invention relates to an end-to-end encryption method based on a mobile network and a communication client side, and further relates to an end-to-end encryption system based on the mobile network and the communication client side. According to the encryption method, the symmetric encryption algorithm is adopted to carry out data encryption, an account number managing center is used for managing the identity and a secret key of an authorized user, a secret key processing module is used for carrying out secret key encryption and decryption on a secrecy system, a terminal processing module is used for carrying out encryption or decryption on the plaintext or ciphertext data information through the symmetric encryption algorithm, and a communication software client side is used for transmitting enciphered data, and accordingly the end-to-end enciphered data interaction is achieved. The encryption system comprises the account number managing center, the secret key processing module and the terminal processing module, the account number management center and the secret key processing module interact through the mobile communication network, the terminal processing module interacts with the enciphered data through the communication software client side, and encryption or decryption on the terminal processing module is achieved. The end-to-end encryption method and the end-to-end encryption system are good in encryption safety and capable of being used for various mobile communication platforms.

Description

technical field [0001] The invention relates to an end-to-end encryption method based on a mobile network and a communication client, and also relates to an end-to-end encryption system based on a mobile network and a communication client. Background technique [0002] In the existing mobile communication system, whether it is a mobile communication network or a communication software used as a data transmission platform, encryption technology exists. [0003] In the mobile communication network, whether it is a public or a professional system, security functions such as authentication and interface encryption are defined to ensure the safe exchange of data. However, in the core nodes of the communication system, these encryption technologies still have information in the form of plain text, which has a low degree of security and cannot meet the high security requirements of the military, government and security departments, and some special users to ensure the confidentiali...

Problems solved by technology

However, since all data is processed by the server of the communication software provider, whether the data is encrypted and stored and how to process it is quite opaque to the user. The security of user data not only has technical risks, but also moral risks.
