With the rapid development of information technology and the Internet of Things,the informationalized level of the power industry is gradually improving,and the digitalization and intelligence of the power supply chain are deepening.However,the ensuing security problems are becoming increasingly prominent,especially in the power system software supply chain,involving supplier management,research and development,production,safety testing and other links,any security loopholes may lead to serious security accidents.In order to improve the security of the power system software supply chain,this paper first analyzes the business characteristics of the power system supply chain,and proposes a power system software supply chain security protection solution based on trusted computing in view of the problems such as lack of supply chain control,increased terminal access security risks and lack of security certification for key control services.The whole chain authentication and security protection architecture from the source of the supply chain to the terminal of the equipment is designed to ensure the integrity,confidentiality and compliance of key business data,and provide a strong guarantee for the safe operation of the power system.
