Construction of Safety Protection System for Power Industrial Control System and Enhancement Design of Communication Protocol

Abstract

Abstract The safe and stable operation of the power system has always been a common problem related to social stability and economic development in the world. To adapt to the development of “Internet +" and energy Internet, to ensure the information security of the power industrial control side, the power industrial control system Information security raises higher requirements. First, the ICS communication model is abstracted, the security risks and threats faced by ICS are sorted out, the most urgent and critical security requirements are clarified, and then a communication enhancement scheme is designed without affecting functions, efficiency, and rapid deployment. This includes one-way authentication and integrity checking of critical communication messages, combined with a timestamp mechanism and registration mechanism. Finally, through the security analysis of the enhanced scheme, it proves that it can resist common attacks such as camouflage, tampering and replay.
