Cooperative intelligent transport systems. Communication profiles. | Status: Current

1 Scope This document specifies a methodology to define ITS-S communication profiles (ITS-SCPs) based on standardized communication protocols to interconnect trusted devices. These profiles enable secure information exchange between such trusted devices, including secure low-latency information exchange, in different configurations. The present document, in order to exemplify the methodology, also normatively specifies some ITS-SCPs based on the methodology, yet without the intent of covering all possible cases. Further ITS-SCPs can be specified at a later stage. Configurations of trusted devices for which this document defines ITS-SCP’s include:

1. a) ITS station communication units (ITS-SCU) of the same ITS station unit (ITS-SU), i.e. station-internal communications;
2. b) an ITS-SU and an external entity such as a sensor and control network (SCN), or a service in the Internet;
3. c) ITS-SUs.

The specifications given in this document can be equally applied to secured and unsecured communications, being groupcast and unicast communications, being localized or networked communications.
