SecDT: A Profile-Based Security Layer for TRDP Communications
Researchers propose a bolt-on cryptographic layer for the Train Real-time Data Protocol, targeting the unprotected multicast traffic that rail operators must now secure under tightening EU transport regulations.

arXiv:2609.03133v1 Announce Type: new Abstract: The Train Real-time Data Protocol (TRDP) is widely used on rolling stock but it provides limited native support for cryptographic protection. Furthermore, the multicast traffic profile used in TRDP Process Data to exchange critical information between onboard subsystems makes the introduction of cryptographic protection a challenge. This paper presents a lightweight security layer for secure TRDP communication that implements a number of security
Editorial Analysis
Rail infrastructure increasingly falls under NIS2 essential-entity requirements, yet legacy OT protocols like TRDP lack native encryption—this research offers an actionable retrofit path.
Review whether your rail or critical-transport OT environments use unprotected TRDP multicast and assess applicability of profile-based encryption overlays.
