Design on Security Communication Protocol of Electricity Acquisition Terminal Based on the Password Techniques

摘要

Based on fresh random challenge response authentication and key agreement, access control, priority control mechanisms, this paper puts forward a security protection communication protocol to guarantee the data transmission security of electricity acquisition terminal and the acquisition host. From the angle of attack detection, this proposed protocol was proved that can resists replay attack, counterfeit attack and information intercepted attack, and can ensure the safety of the electricity power acquisition system overall.
