Abstract
To improve Message Authentication Code(MAC) algorithm of ER in Railway Signal Safety Communication Protocol n(RSSP-Il), an improved MAC algorithm using Advanced Encryption Standard(AES) as core algorithm and Cipher Block Chaining(CBC) as encryption and decryption method is put forward. The proposed method will be applied to RSSP-II simulation test in TSRS test platform of CTCS-3, whose results show that the improved algorithm conquers such safety problems as weak key and semi weak key, thus having more advantage in safety and real-time compared.关键词
