Abstract
With the development of metro, the information safety of train control system has become a key element in closed transmission. This paper proposes an improved railway signal safety protocol I (RSSP-I) based on commercial cryptography 4 (SM4) for metro train control system. RSSP-I is mainly used for safety-related communication in closed transmission system and cannot defense the disguise threat. This paper improves RSSP-I protocol based on SM4 to defense the disguise threat, and can protect against repeat, loss, insertion, disorder, corruption, delay and disguise threat. The protocol proposed in this paper can strengthen the security of information transmission process.
