ETSI ETSI TS 102 941 V1.2.1 (2018-05)6 1 Scope The present document specifies the trust and privacy management for Intelligent Transport System (ITS) communications. Based upon the

26、 security services defined in ETSI TS 102 731 1 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 element

27、s of the ITS reference architecture defined in ETSI EN 302 665 2. The present document identifies and specifies security services for the establishment and maintenance of identities and cryptographic keys in an Intelligent Transport System (ITS). Its purpose is to provide the functions upon which sy

28、stems of trust and privacy can be built within an ITS. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
