ITU-T Recommendations

Recommendation ITU-T X.1372 provides security guidelines for vehicle-to-everything (V2X) communication systems. V2X is a generic term for the communication modes termed as vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-nomadic devices (V2D) and vehicle-to-pedestrian (V2P) discussed in this Recommendation.

Significant developments have taken place over the past few years in the area of vehicular communication in the intelligent transportation system (ITS) environment. The V2X communication significantly improves road safety, decreases traffic congestion and increases convenience. However, V2X communication also makes relevant entities in the ITS environment vulnerable to various forms of cyber-attack.

To address this security problem, this Recommendation identifies threats in V2X communication environments and specifies security requirements for V2X communication to mitigate these threats. This Recommendation also provides description of possible implementation of V2X communication with security.
