Abstract: In order to improve the security and reliability of high speed railway signal system, according to the safety assessment technology and method recommended by IEC62425 standard, the security requirement and index were studied, which is suitable for CTCS-3 train control system and includes system security risk matrix, distribution of safety risk acceptance criteria, safety requirements and safety related applications conditions, etc. The stages of CTCS-3 train control system in the whole life cycle were divided, and the applicable safety assessment technology, safety assessment work flow and key activities in each stage of life cycle assessment were discussed. The research shows that the security evaluation system of ctcs-3 train control system, which meets the requirements of IEC62425 standard, can effectively identify the weak links of system operation function, interface function and data transmission, and create favorable conditions for the security implementation of system functions.

Key words: IEC62425, CTCS-3 train control system, safety technology, as low as reasonably practicable (ALARP), signal system life cycle
