AI Technical Summary

Technical Problem

Traditional industrial security software deployment methods are easily tampered with, especially those using USB deployment and online operating system upgrades, which pose security risks and make it difficult to guarantee the reliable operation of the software.

Method used

A virtual space is built within the reserved area of ​​the BIOS to store the security software system. The security of the code is ensured through encryption layers and decryption programs. Data can only be modified or accessed after authorization, thus realizing the deployment of hardware-based secure software.

Benefits of technology

It improves data security and privacy, prevents virus tampering, ensures the reliable operation of industrial security software, and enables the CPU to quickly and in real time retrieve data.

Abstract

The application discloses an industrial safety software solidification system, and technical scheme points are as follows: when the system is prepared, a chip area of a BIOS is identified, the BIOS chip area comprises a BIOS starting boot area, a reserved area, a BIOS program area, a high-end address area and a BIOS ROM area, the reserved area is positioned and a virtual space area is constructed in the reserved area, a safety software system is stored in the virtual space area according to a balanced storage strategy, the safety software system is burned into the virtual space area based on a solidification mode, after the solidification of the safety software system is completed, the safety software system stored in the virtual space area is mapped into a memory space when the system is started, an interface strategy is embedded in the memory space, and the interface strategy is used for calling data in the safety software system or storing data into the safety software system.
