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.
