Problems solved by technology

[0003] At present, most domestically-made trusted computers still use foreign chips for their underlying key chips and north-south bridges. In this way, all instructions issued by domestic CPUs must be processed by foreign bridges. The connected network ports, hard disk interfaces, Peripheral information such as the USB interface may be stolen, bringing great security risks

Abstract

The data processing method and device of a trusted security terminal provided by the present invention include: making the control unit of the motherboard work before the BIOS; performing credible measurement on the BIOS, and when the measurement result is normal, start the operating system after normally running the BIOS; otherwise , so that the main board enters the alarm mode or shutdown mode from the standby state; reads the data to be processed and the security key, and performs encryption and decryption operations on the data to be processed according to the algorithm of the security key; All operations can establish a trusted connection, which greatly improves the security of user data operations and is suitable for the field of data security.

Description

technical field [0001] The present invention relates to the technical field of trusted computers, in particular to a data processing method and device of a trusted security terminal. Background technique [0002] With the development of Internet technology and information technology, the importance of information security is self-evident, and people put forward higher requirements for computer security. [0003] At present, most domestic trusted computers still use foreign chips for their underlying key chips and north and south bridges. Since then, all instructions issued by domestic CPUs must be processed by foreign bridge chips. The connected network port, hard disk interface, Peripheral information such as USB interfaces may be stolen, which brings great security risks. SUMMARY OF THE INVENTION [0004] Aiming at the deficiencies in the related art, the technical problem to be solved by the present invention is to provide a data processing method and device for a trus...
