Access control with identity authentication becomes crucial for critical circuit breaker operation in the substation automation system. According to IEC 61850, the implementation of access control policy depends on a virtual access view. But the standard only defines a concept to resolve the access control problem; neither the virtual access view nor the password verification procedure has proposed implementation measures. This paper designs security management of IED data and security state machine of access control for control object, to realize identity authentication and to generate the virtual access view. At last, this paper describes operation sequence with access security in order to introduce the application of this access control method
