Application of Domestic Cryptographic Password in ISCS of Urban Rail Transit

Through indepth analysis of the four types of security risks that may exist in the integrated supervision and control system (ISCS) of urban rail transit, the corresponding domestic cryptographic password application scheme is adopted to dissolve the security risks, ensuring the safety, independency and control of key infrastructure of urban rail transit, and promoting the ecological and healthy development of domestic cryptography industry. The domestic cryptographic password is applied in the integrated monitoring system of the underground traffic engineering in Zhengzhou citizen cultural service area, covering 1 center, 6 stations and 1 depot. Since the launch in October 2019, the system has been operating safely and stably.
