Abstract: AbstractWith the advance of smart grid construction, the number of users increases, and the twoway interactive communication is stronger and stronger, application system is more integrated, and there are risks that the system integrity, confidentiality and availability of business system integrity is destroyed and smart devices, intelligent terminals and users' terminals are illegally fraudulent, illegally remotely controlled and illegally operated. The lifecycle security framework of smart grid applications is proposed, which defines seven aspects of security requirements including the planning, requirements, designment, development, testing, online operation and maintenance and the abandoned part, making information security technology and management measures cover the entire software life cycle.

Key words: smart grid, information security, lifecycle, classified protection, security design
