ETCS KMC

An ETCS Key Management Centre (KMC) is a tool to help create and manage ETCS encryption keys (KMACs / KTRANSs / K-KMCs). These keys are necessary as part of the protocol for exchanging messages between on-board ETCS equipment and trackside ETCS equipment when operating in ETCS Level 2 and Level 3, and for securely transporting the keys to the ETCS equipment.

DARD Consulting Limited has developed an off-line KMC, which is used in the UK by Network Rail, that enables generation of SS-114 and SS-038 compliant messages that contain key management commands between the KMC and trains/RBCs.

Please get in touch if you would like to discuss use of this tool or if you need help with developing your own off-line or on-line key management solution.

Below are screen shots of the current version of the tool illustrating its capabilities.

Once keys are created (and saved), keys can be exported either to the applicable RBC/train, or to another KMC. Export ETCS keys
