With the advancement of the digital transformation of railway power supply system, a large number of railway power supply operation data has been centrally managed, analyzed and utilized. How to better protect the security and privacy of relevant data has become one of the important problems to be solved in the current railway industry. This study proposes a multi-level secure access algorithm for railway power supply big data based on attribute encryption, which can achieve refined data control and privacy protection based on the application of various technical means, such as flexible access control strategy and user identity concealment. The final results show that the algorithm has excellent performance in data security, access efficiency, system reliability and other aspects, and can meet the data security management requirements in the field of railway power supply.
