铁路商用密码应用安全性评估实施研究OA

Targeting at railway operation entities,this paper elaborates the system framework,legal basis,and standard requirements of the security assessment for commercial cryptography application.It proposes a comprehensive workflow for cryptography application and assessment,covering technical preparedness,planning and design,construction and implementation,and operation and maintenance,thereby providing a clear path for systematic implementation.This paper provides an in-depth analysis of the key focuses and security requirements for cryptography application in railway systems across the physical and environmental,network and communication,device and computing,application and data,as well as management system dimensions.Furthermore,it offers practical case studies on cryptography application and assessment from the perspectives of application data transmission and network communication channel protection,aiming to provide a practical guide for railway operation entities.
