Problems solved by technology

[0003] At present, for the consistency of the railway signal safety communication protocol, it basically relies on the communication and exchange between developers to find the difference in the protocol generation method. This method not only increases the communication cost, but also has low efficiency; in the prior art , regarding the consistency of railway safety communication protocols, there is still a lack of automated testing methods, and there is also a lack of practical testing solutions

Abstract

The embodiment of the invention provides a railway secure communication protocol conformance testing method. The method comprises establishing a communication link of equipment under test; using testequipment as a man-in-the-middle of the equipment under test through an ARP protocol; using the test equipment to capture data packets of the equipment under test, and conducting a static conformancetest of a frame format based on a standard knowledge base; and tampering key bytes, and conducting a dynamic conformance test of a protection mechanism based on the standard knowledge base. The methodprovided by the invention solves the problem of efficiency of a conformance test scheme, and can quickly and accurately test whether a secure communication protocol of a railway signal system conforms to the specification.

Description

technical field [0001] The invention relates to the technical field of network signal security, in particular to a method for testing the consistency of railway security communication protocols. Background technique [0002] RSSP (Railway Signal Safety Protocol, railway signal safety communication protocol) is the basis for guaranteeing railway key control information, control logic availability, credibility and confidentiality. The "Railway Signal Safety Communication Protocol" standard specifies the frame format, transmission mechanism, etc. However, due to the different understanding of the protocol by developers, the railway signal safety communication protocol has no small differences in practical applications. In view of the urgent need for interconnection of railway signal systems, there is a strong practical need to ensure the consistency of communication protocols of different manufacturers. [0003] At present, aiming at the consistency of railway signal safety co...
