本申请要求于2017年10月25日递交的中国专利申请第201711007878.8号的优先权,在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
技术领域
本公开涉及安全通信技术领域,特别涉及一种RSSP-II安全协议分离部署方法。
背景技术
在轨道交通信号控制系统中,安全信息需要在多种安全设备之间进行传递,既有地面设备之间在封闭通信网络中的通信,也有车载设备与地面设备支架通过开放网络交换数据。信息在通信网络中的传输,需要采取一定的技术手段,达到一定的安全标准,才能保证信息本身的安全性和可靠性。
RSSP-II安全通信协议是广泛应用的基于以太网通信的安全通信传输协议规范,其结构示意图如图1至图2所示,可应用于封闭传输系统和开放传输系统,应用于高铁、城际铁路以及城轨交通信号控制系统中。
在现有的铁路安全计算机系统中,多采用二乘二取二计算机结构,双套冗余设计,一般为两种平台实现方法:如图3所示,第一种不区分安全功能和非安全功能,每系均包含A/B机。如图4所示,第二种将安全功能与非安全功能区分开来,每系均包含安全逻辑处理单元A/B机和通信单元C机。其中,逻辑处理单元A/B机承担安全功能,通信单元C机不承担安全功能,逻辑处理单元和通信单元之间通过以太网方式进行数据交互。
但是,当前在部署RSSP-II安全通信协议的时候,由于实际环境中的平台结构不同,当前部署的RSSP-II安全通信协议的方法无法满足不同平台结构的需求。
发明内容
本公开的目的在于提供一种RSSP-II安全协议分离部署方法,以提高部署的RSSP-II安全通信协议的多样性,实现对不同架构平台的分离部署。
为实现以上目的,本公开采用的技术方案为:提供一种RSSP-II安全协议分离部署方法,包括如下步骤:
为协议栈增加不同的适配层;
利用相应的适配层,将协议栈所有RSSP-II的功能模块编译为库文件部署至A、B和C机中。

在区分安全功能和非安全功能时,将协议栈RSSP-II的安全相关模块编译为库文件部署至A/B机中,以及将非安全模块编译为库文件部署至C机中,其中,AB机为协议栈增加系统适配层和应用适配层,C机为协议栈增加网络适配层和应用适配层。
其中,所述的利用相应的适配层,将协议栈所有RSSP-II的功能模块编译为库文件部署至A、B和C机中,还包括:
将协议栈RSSP-II的安全相关模块MASL层单独编译为Subset-037的SFM模块,并部署在A/B机中,其中为协议栈增加系统适配层和应用适配层。
其中,所述的利用相应的适配层,将协议栈所有RSSP-II的功能模块编译为库文件部署至A、B和C机中,还包括:

与现有技术相比,本公开存在以下技术效果:本公开在RSSP-II安全通信协议核心逻辑层周边开发一系列适配层,然后根据目标平台的架构和功能模块的类型,为协议栈增加对应的适配层并将不同功能模块编译为库文件部署至平台中,如此可将RSSP-II通信协议开发为跨平台可移植性的通用安全软件协议库,实现了对不同架构平台的协议部署。
