面向智能铁路信号系统的内生安全范式OA

As safety-critical systems,rail signaling systems have long prioritized functional safety guarantee.However,with the increasing networking and digitalization and the in-depth integration of intelligent technologies,rail signaling systems face increasingly severe risks in both functional safety and cybersecurity.Against this background,this paper systematically analyzes the security risks faced by rail signaling systems to identify the security requirements and challenges of rail signaling systems.Then,it proposes secure-by-design paradigm for intelligent rail signaling systems,conducting an in-depth study from four dimensions:theoretical models,key technologies,standards and specifications,and equipment design.Furthermore,it demonstrates through examples how the proposed paradigm can be implemented for the secure design and upgrade of intelligent rail signaling equipment,offering effective support for the safety and efficiency improvement of rail transport.
