Abstract

Abstract: Aiming at the low security and low real-time performance of the message authentication security layer (MASL) message authentication code (MAC) algorithm in the railway signal security communication protocol RSS-II, the advanced encryption standard AES is used as the core algorithm of the MAC code and the ciphertext is used Packet link encryption and decryption of the message, simulation of the security protocol from the security-related key service process of the RSSP-II communication protocol, verification of the confidentiality of the improved protocol, and optimization of the protocol key service process, that is, the key The center uses the advanced encryption standard AES algorithm to authenticate the vehicle equipment and the ground wireless block center, further strengthening the security of the protocol.
