Self-adaptive substation longitudinal encryption host verification method and terminal

Abstract

The invention discloses a self-adaptive substation longitudinal encryption host verification method and a terminal. The method comprises the following steps: establishing connection with a longitudinal encryption host, and acquiring and identifying configuration information; establishing a virtual tunnel for the longitudinal encryption host according to the configuration information, and generating a verification case according to the configuration information; performing tunnel strategy verification on the virtual tunnel according to the verification case to obtain a verification result, and performing strategy consistency comparison with a preset strategy information table according to the verification result to obtain a comparison result; according to the comparison result, correcting the tunnel strategy, and generating an analysis report. According to the method, the problem of automatic verification of the longitudinal encryption host of the transformer substation is solved, automatic verification of a whole strategy information table covered by multiple channels is realized, adaptive verification and correction of different encryption host models are realized, manual intervention is not needed, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a verification method and a terminal for an adaptive substation longitudinally encrypted host. Background technique [0002] With the extensive use of network equipment, equipment monitoring and the promotion of the Internet of Things, the network security of the power monitoring system has become one of the indicators for measuring the safe and stable operation of the power system. In the "Guidelines for Network Security Protection of Electric Power Monitoring System", the basic protection principles have been clarified: security partition, dedicated network, horizontal isolation, and vertical authentication. At present, the use of vertical encryption and authentication devices in most power monitoring systems is an important measure for network security protection of power monitoring systems. [0003] The verification of the vertical encryption authentication host (devic...

AI Technical Summary

Problems solved by technology

[0004] (1) If the business is disconnected during the verification process, the fault point cannot be accurately judged, and it is highly dependent on business equipment and personnel skills

[0005] (2) Only one service can correspond to one policy during verification, that is, each tunnel policy can only be verified separately, and mass and multi-channel verification cannot be realized

[0006] (3) Long calibration time

With the increase of business access, the configuration of tunnel policies is increased. According to the existing technical conditions, the required verification time is increased.
