SecDT: A Profile-Based Security Layer for TRDP Communications
A proposed security layer for TRDP addresses the lack of cryptographic protection in train communications—relevant for European rail operators and NIS2-scoped transport entities.

arXiv:2609.03133v2 Announce Type: replace 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 secur
Editorial Analysis
European rail operators increasingly fall under NIS2 scope; TRDP's lack of crypto protection is a systemic gap that SecDT aims to address.
If your organisation operates rail systems using TRDP, assess this profile-based security overlay against your NIS2 risk-treatment plan.
