Abstract

The invention provides a data transmission and storage method and system. The data transmission method comprises the steps that plaintext and plaintext abstracts in an unsecured environment are encrypted, and corresponding encrypted data and secret keys are obtained; the encrypted data is transmitted to a preset first receiving end in the unsecured environment through a first transmission tool; the preset first receiving end activates a preset second receiving end in a secure environment, and the encrypted data is transmitted to the preset second receiving end; after the secrete keys are encrypted through a second transmission tool, a secret key file is formed and transmitted to the second receiving end; the secrete key file received by the second receiving end is decrypted to obtain the secrete keys in the secret key file; the encrypted data received by the second receiving end is decrypted according to the obtained secret keys to obtain the corresponding plaintext and plaintext abstracts, and the integrity of the plaintext is verified according to the plaintext abstracts. According to the data transmission and storage method and system, the secret keys and the encrypted data are subjected to time-share transmission through different transmission channels, the transmission security is improved, and the plaintext cracking difficulty is increased.

Description

technical field [0001] The present invention relates to the technical field of data management, in particular to the technical field of data transmission and storage, specifically a data transmission and storage method and system. Background technique [0002] Arm Trustzone technology is a comprehensive security solution. Its security design runs through processors, buses, system modules, peripherals, operating systems and applications to ensure the security of devices developed using it. Trustzone is closely related to Arm CortexA series processors, and security information is transmitted between the entire system and peripheral IP through the AMBA AXI bus, so as to prevent memory, encryption module, keyboard, display and other modules from being attacked by software. [0003] The device security system developed using Trustzone technology needs to include TEE (secure execution environment), secure kernel program, security service and TA (trusted application). The device-b...
