The intelligent distribution network is an important hub for connecting power generation and users, and the security of its information is closely related to the stable operation of the power grid. In order to solve the contradiction between the security and real-time of information in intelligent distribution network according to Supplementary Provisions for Safety Protection of Medium and Low Voltage Distribution Network Automation System, an information security model of intelligent distribution network is proposed, after deeply studying AES encryption algorithm and SHA-256 authentication algorithm, using OPNET as simulation software for smart distribution network information to carryout transmission delay curve. FPGA is used as information security processing platform. We obtain the total delay, analyze the integrity and availability. The experiment proves that the intelligent distribution network information security processing solution satisfies the three elements of CIA information security, and has good confidentiality, integrity and availability.
