| Abstract: | Due to the restrain of network structure and mobility of user terminal, there are some potential threats in GSM-R system. The purpose of this paper is to improve schemes for the existing security leaks in GSM-R system. Considering the application of GSM-R system in railway and secure demands on it, security technologies adopted by GSM-R system and security leaks are briefly depicted. Bi-directional authentication and end-end encryption, which are the improved schemes of uni-directional authentication and restrict of information encryption respectively, are described in detail in this paper. |
