Based upon the security services defined in ETSI TS 102 731 [i.23] and the security architecture defined in ETSI TS 102 940 [5], it identifies the trust establishment and privacy management required to support security in an ITS environment and the relationships that exist between the entities themselves and the elements of the ITS reference architecture defined in ETSI EN 302 665 [i.25].

The present document identifies and specifies security services for the establishment and maintenance of identities and cryptographic keys in an Intelligent Transport Systems (ITS). Its purpose is to provide the functions upon which systems of trust and privacy can be built within an ITS.
