RSSP-I security protocol separation and deployment method

Abstract

The invention discloses an RSSP-I security protocol separation and deployment method and belongs to the technical field of secure communication. The RSSP-I security protocol separation deployment method comprises the following steps of adding different adaptation layers for a protocol stack, wherein the adaptation layer comprises a D interface adaptation layer, an application adaptation layer, a network adaptation layer and a system adaptation layer; and compiling all the RSSP-I function modules of the protocol stack into a static logic library, and deploying the static logic library to an A machine, a B machine and a C machine by using the corresponding adaptation layers. According to the method in the invention, a series of adaptation layers are developed on the periphery of the RSSP-I safety communication protocol core logic layer; and then, according to the structure of the target platform and the type of the function modules, the corresponding adaptation layer is added for the protocol stack, and different function modules are compiled into a static logic library file to be deployed into the platform, so that the RSSP-I communication protocol is developed into a universal safety software protocol library with the cross-platform transportability, and protocol deployment of different architecture platforms is realized.

Description

technical field [0001] The invention relates to the technical field of secure communication, in particular to a method for separating and deploying RSSP-I security protocols. Background technique [0002] The RSSP-I secure communication protocol is suitable for safety-related communications in closed transmission systems to ensure the security of data interaction in a closed transmission system environment, to ensure the security of data transmission between safety-related products, and to improve data transmission reliability and availability. [0003] In the existing railway safety computer system, the two-by-two computer structure is mostly used, and the double-set redundancy design is generally implemented by two platforms: such as figure 1 As shown, the first type does not distinguish between safety functions and non-safety functions, and each series includes A / B machines. Such as figure 2 As shown, the second type distinguishes the safety function from the non-safe...

Problems solved by technology

[0004] However, when deploying the RSSP-I secure communication protocol at present, due to the different platform structures in the actual environment, the method of the currently deployed RSSP-I secure communication protocol cannot meet the needs of different platform structures
