Embodiment Construction

[0039] Such as figure 1 As shown, a process-level safety test system based on IEC62351 is composed of the following modules: man-machine interface UI, message editing module, storage module, SCD (ie total station system configuration file) analysis module, communication module;

[0040] The man-machine interface UI: used for interacting with testers, can complete editing messages, import SCD files, call / save test cases, and control outsourced operations.

[0041] The message editing module is used for the user to configure GOOSE / SV messages based on the IEC61850 protocol through the man-machine interface. The message editing interface will prompt the user to fill in a set of private keys, and the content of the private key can be any set of characters. The message editing module adds the GOOSE / SV message verification and signature algorithm based on the encoding of the process layer message based on the IEC61850 protocol, so that the GOOSE / SV message conforms to the IEC62351 protoc...

Abstract

The invention aims to provide an IEC62351 (International Electrotechnical Commission 62351)-based process layer safety test system which effectively verifies whether process layer network equipment has tamper-proof and anti-replay safety functions. The system consists of the following modules: a human-computer interface UI (User Interface), a message editing module, a storage module, an SCD (namely substation configuration description) analysis module and a communication module. The invention also provides an IEC62351 (International Electrotechnical Commission 62351)-based process layer safety test method. By using the system and the method, an IEC62351 specification-based process layer message can be edited. The EC62351 specification-based process layer message is edited according to the principle that the message check and signature algorithm is increased based on the EC62351 specification-based process layer message, so the message meets the EC62351 specification. Any field of the edited EC62351 specification-based message can be modified. Thus the message tamper attack and message replay attack to to-be-tested equipment can be simulated to verify whether the to-be-tested equipment has defense capacity.

Description

Technical field [0001] The present invention relates to the field of electric power engineering and debugging, in particular to the field of electric power business process-level security, and in particular to a process-level security test method and system based on IEC62351. Background technique [0002] With the continuous popularization and promotion of intelligent substations, the degree of informatization and automation of power systems continues to increase. However, the lack of protocol security makes it possible for an attacker to bypass the peripheral physical protection measures and directly enter the dispatch center or substation, and then directly control the field equipment through the communication protocol. Safety, safety protection and reliability have always been important issues in system design and operation in the power industry. The security reform based on the IEC 62351 protocol has played a very important role in preventing the above risks. [0003] At pres...
