Abstract

This application discloses a design method and system of a trusted TCM software stack based on the Linux operating system, which can realize the communication and interaction between the upper layer application of the domestic Linux operating system and the trusted TCM chip, realize trusted computing, and ensure data integrity and authenticity, resistance to tampering attacks, safe execution of code, protection of confidentiality of sensitive data, etc. The resource management of trusted TCM chips is added to the Tcs layer of the Trousers software stack to better solve the bottleneck of limited resources of trusted TCM chips and improve the utilization rate of trusted TCM chip resources for users.

Description

technical field [0001] The present application relates to the field of trusted TCM software stacks, in particular to a design method and system for a trusted TCM software stack based on a Linux operating system. Background technique [0002] With the continuous development of computer applications, the problem of security threats is becoming more and more serious, and traditional relying solely on software to resist security threats often cannot solve the problem. The main technologies of traditional information security are firewall, intrusion detection and antivirus software. When the firewall is built higher and taller, the intrusion detection becomes more and more complex, and the virus database becomes larger and larger, the overall information security situation still has a trend of becoming more and more complicated and chaotic: false alarm rate increases, security investment continues to increase, maintenance and management It is more complex and difficult to implem...
