Power distribution terminal communication encryption protocol detecting method

Abstract

The invention relates to a power distribution terminal communication encryption protocol detecting method. The power distribution terminal communication encryption protocol detecting method is characterized in that a power distribution terminal communication encryption protocol detecting management module sets parameters of a power distribution terminal; a power distribution terminal connectivity test module carries out a power distribution terminal connectivity test; a power distribution terminal ciphertext remote control command protocol test module carries out a power distribution terminal encrypted remote control command protocol test; a power distribution terminal plaintext remote control command protocol test module carries out a power distribution terminal plaintext remote control command protocol test; a test report module generates a power distribution terminal communication encryption protocol detecting and analyzing report automatically according to test strategy options and a test result. The power distribution terminal communication encryption protocol detecting method is reasonable in design, the automatic and real-time online detecting function for power distribution terminal connectivity validity, encrypted remote control command operating validity and plaintext remote control command operating violation is achieved, power distribution terminal communication encryption protocol detecting efficiency and accuracy are improved, and safety is ensured when the power distribution terminal carries out remote control commands.

Description

technical field [0001] The invention belongs to the technical field of information security, in particular to a method for detecting a communication encryption protocol of a power distribution terminal. Background technique [0002] Distribution automation is an important part of the realization of intelligent distribution network. It is based on the primary grid and equipment, takes the distribution automation system as the core, and comprehensively utilizes various communication methods to realize the monitoring and control of the distribution system. The distribution automation system is mainly composed of distribution master station, distribution terminal and communication channel. The electrical automation system should support the one-way authentication function based on asymmetric key technology. The remote control commands issued by the power distribution master station should have a digital signature based on the dispatch certificate, and the power distribution term...

Problems solved by technology

[0003] At present, the power distribution automation system has been reconstructed or newly built in accordance with this requirement, but some power distribution terminals still support the receipt and operation of plain text remote control commands for various reasons, resulting in the hidden danger of the switch being remotely maliciously controlled by the power distribution terminal. The specialty has not yet developed a set of detection methods suitable for the compliance of the distribution terminal communication encryption protocol
