---This is the first revision:IntroductionIf a safety-related electronic system involves the transmission of information between different locations, the transmission system becomes an integral part of the safety-related system: points, and according to GB/T 28809, end-to-end transmission security is specified: The transmission systems considered in this document are used for the transmission of information between different locations and generally have no specific prerequisites that need to be fulfilled: From a security perspective, the system is not trustworthy or completely trustworthy: This document is dedicated to the requirements for security-related information transmission considerations under such transmission systems: This document does not consider RAM related content, but it is a major aspect of global security: Safety requirements depend on the characteristics of the transmission system: To simplify the complexity of the method of proving system security, 3 types of transmissions are considered system: ---Category 1 includes systems that are controlled by the safety system designer and remain fixed during their life cycle; ---Category 2 is a system that contains partially unknown or unfixed parts, but excludes unauthorized access; ---Category 3 is a system that is not under the control of the designer and where unauthorized access is contemplated: Previously, the requirements for Category 1 systems were specified in GB/T 24339:1-2009, and the requirements for other systems were specified in GB/T 24339:2-2009 stipulated in: When a safety-related communications system certified to the above standards requires maintenance or expansion, use Appendix A to review the terms of this document and the previous The terms of the series of standards are traceable: Rail transit communication, signaling and processing systems Safety-related communications in transmission systems1 ScopeThis document specifies the basic requirements required to enable safety-related communication between safety-related equipment connected to transmission systems: This document applies to safety-related transmission systems for digital communications that are not necessarily designed for safety-related systems, but rather: ---Under the control of the designer and fixed during the life cycle; ---Parts are unknown or not fixed, but unauthorized access can be ruled out; ---Not under the control of the designer and contemplates unauthorized access: Both safety-related and non-safety-related equipment can be connected to the transmission system: Safety requirements are usually implemented in safety-related equipment designed according to GB/T 28809: In some cases, as long as safety measures are in place Meet assigned safety requirements, which may be implemented in other relevant equipment of the transmission system: The safety requirements specification is a prerequisite for the safety argument for safety-related electronic systems, and the evidence (including quality) required for the safety argument Management and safety management, etc:) are specified in GB/T 28809: This document does not apply to existing systems prior to the release of this document: The following terms are not defined in this document: ---Transmission system; ---The equipment connected to the transmission system; ---Solutions (such as: interoperability); ---Definition of safety-related data: Security-related devices connected through open transmission systems may be subject to a variety of different IT security threats: Overall solution, including management, technical and operational aspects: Information security in this document only considers intentional attacks on security-related applications via messages: This document does not cover general information security issues, and specifically does not include the following information security issues: ---Ensure the confidentiality of security-related information; ---Prevent transmission system overload:2 Normative reference documentsThe contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document;
