Abstract There are many kinds of professional apps in station control system of intelligent substation. In this open and shared ecosystem, there are great security risks in app authorized installation, resource control, access control, and border protection. In this paper, a new approach of app security management based on blockchain technology has been proposed. By using the mechanism of tamper free and traceable "ledger" based on cryptography, the objective and traceable supervision of app's life cycle can be implemented through customization of blockchain's ledger. This paper provides a new solution for app security management of station control system in intelligent substation.
