Description

technical field [0001] The invention belongs to the field of network information security, and in particular relates to an electric power trusted and safe communication system based on a trusted computing module. Background technique [0002] A large number of control terminals used in the power system industrial control system are designed with embedded systems. The embedded system has the characteristics of low power consumption and adaptability to harsh working environments, but it also limits the application of network security technology in power terminals. Many power terminals currently in use have no network security protection measures, or only adopt simple security protection measures. With the increase of attacks against industrial control systems, it is necessary to adopt new technologies to improve the defense capabilities of power industrial control systems in the face of security risks. [0003] Most of the power control terminals are deployed on electric pole...

AI Technical Summary

Problems solved by technology

[0005] At present, there are many security protection technologies that can realize the protection of the network and the main station, but there is still a lack of protection means for the control terminal embedded in the electric power

Since the power embedded control terminal is subject to the terminal's processing performance, power consumption requirements, hardware resources and other conditions, many security protection methods cannot be used, so the current security protection for the control terminal is still very weak

[0006] At present, the idea of ​​trusted computing has been recognized in the field of information security. Many network devices have the function of trusted computing. However, due to the wide variety of principles and designs of power embedded control terminals, it is difficult to unify the standard. For each control terminal It is unrealistic to independently develop trusted computing functions, which affects the popularization and application of trusted computing in power embedded control terminals
