摘要

The Communication Based Train Control (CBTC) system is the development trend of railway signaling. The Chinese railway has made a strategy to develop the Chinese Train Control System (CTCS), which is divided into 5 levels (from level 0 to level 4). In level 3 and level 4, CBTC based on GSM-R network will be realized. Chinese railway is now developing the Radio Based Cab Signaling (RBCS) system as the first attempt on CBTC. Preliminary field tests of the approaching continuous RBCS based on a commercial radio data transceiver have been finished with satisfactory results. This year, a long and exhaustive test of GSM-R based RBCS will be carried out on the pilot project of the Qinghai-Tibet railway. Because the vital data related to train operation safety is transmitted in the open communication network, it is easy to be modified or attacked maliciously. Therefore, data transmission safety is a vital factor to be considered in GSM-R based RBCS. This paper will focus on the data transmission safety in the GSM-R based RBCS, primarily about the cryptographic techniques and key management.
