Transmission Security Platform for Transportation Information based on BeiDou Navigation Satellite System

Applications of BeiDou Navigation system are in highly developing. However, the urgent insufficient security of navigation data causes it easily stolen and tampered in vehicle transport systems. An information encryption transmission based on PKI technology is a crucial tendency. In this paper, we analyze the feasibility of PKI applications for satellite navigation based transportation system and propose a model of secure information transmission platform (SITP). We also give a PKI key generation method and design a systematic scheme of a network and software system.
