A Study of Secured Transmission Frame and Method for Railway Signaling System

초록

Recently, railway signaling system using radio communications is being operated in the foreign countries, and currently, the railway signaling system using radio communications is being operated in Korea also with some light rail transit systems as its center, and at the same time, studies for localization are under progress. In the railway signaling system using these radio communications, transmission technology which secures higher security is required in the data transmission process between wayside and on-board control equipment. Accordingly, encryption-related study to prevent falsification or counterfeit, etc. of MAC frame by the unauthorized person is a very important element in the transmission system between wayside and on-board equipment. This paper proposed a new MAC frame structure which supplemented WPA2(Wi-Fi Protected Access 2) to be applied to this radio communication based train signaling system.
