Multicast group based autonomous train control system security device supporting plug and play

摘要

The present invention relates to a security device for a multicast group-based train running control system that supports plug-and-play. In order to defend a rapidly evolving cyberattack technology, a security device independent of the train running control system is applied to replace the device and replace the existing system. Because it is easy to interoperate with the multicast address and decides whether to encrypt or decrypt it, it is possible to distinguish secure and non-secure communication only by the recipient address when configuring the train running control system group, so plug and play that does not require additional setting procedures It provides a multicast group-based train running control system security device that supports
