运用于京沪高铁动车组WTD技术中的加密算法与运行保障机制
Encryption and operating safeguard mechanisms of WTD technology used in Beijing-Shanghai high-speed railway
摘要
Abstract
WTD technology (Wireless Transformation Device Technology) can collect, process and send real-time information of CRH EMU through communication between equipped WTD and CRH EMU, which make ground information system monitor and manage those CRH trains efficiently. For WTE technology in Beijing-Shanghai high-speed railway, it is urgent to consider the need of security communication and operating safeguard. In this paper, by introducing Blowfish encryption algorithm and specifically designed operating safeguard mechanisms, it proves that such advancements can not only guarantee the security communication of WTD, but also provide steady and robust data transmission.关键词
