Abstract

The invention discloses a safe computing platform. The safe computing platform comprises a main processor (1), a South Bridge chip (2), an I / O interface (3), a BIOS chip (4), a user key (5), a hard disk (6), a credible hardware module (7) and a PMC connector (8), wherein the main processor (1) is in bidirectional connection with the South Bridge chip (2); and the safe computing platform is electrified to be started. The credible hardware module (7) is electrified for self-detect initialization first and then restore the main processor (1); at the same time, a safe control unit (9) in the credible hardware module (7) compares BIOS data; if the BIOS data passes the comparison, the main processor (1) is normally started and directly accesses the BIOS chip (4); and the platform finishes hardware-level identity authentication, I / O port control and data real-time encryption / decryption based on the safe hardware module (7). A new mainboard structure is adopted to implement various hardware-level safe control measures, so that the safety of the whole computing platform is effectively ensured.

Description

technical field [0001] The invention relates to a computing platform, in particular to a safe computing platform. Background technique [0002] At present, general-purpose secure computing platforms include: main processors, chipsets, I / O interfaces, and BIOS chips. These secure computing platforms usually rely on foreign commercial products, and core components may have technical backdoors. Therefore, some manufacturers have begun to develop The secure computing platform of the Loongson processor, the domestic computer ensures the credibility of the platform at the core component level, but while achieving versatility and ease of use, it often ignores the secure startup of the computer terminal, exposing a great security risk . On the other hand, most of the current secure computers implement security control measures such as identity authentication, port control, and data encryption based on the software level, which greatly improves the security of the system. However, t...
