ETSI ETSI TS 102 940 V1.3.1 (2018-04)6 1 Scope The present document specifies a security architecture for Intelligent Transport System (ITS) communications. Based upon the

24、security services defined in ETSI TS 102 731 4, it identifies the functional entities 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 1. The present docum

25、ent also identifies the roles and locations of a range of security services for the protection of transmitted information and the management of essential security parameters. These include identifier and certificate management, PKI processes and interfaces as well as basic policies and guidelines fo

26、r trust establishment. 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.

41、 ETSI EN 302 665 1 describes an ITS station architecture based upon four processing layers identified as follows: Access Layer; Networking Facilities Layer; and Applications Layer. These horizontal layers are bounded on each side by a vertical Management entity and a Security entity (Figure 1). Figu

42、re 1: ITS station architecture (from ETSI EN 302 665 1) The layers in this architecture do not represent directly the Open System Interconnect (OSI) protocol modelling layers but the functionality expected in each can be mapped to OSI model quite simply. Having mapped the OSI protocol layers to the

43、ITS station architecture, this can be extended into an ITS communications architecture in which the protocol layers communicate on a peer-to-peer basis as shown in Figure 2.

44、ations groups and their communication characteristics ETSI TR 102 638 i.1 defines the basic set of ITS applications which it divides into groups according to the functionality provided. Based on this a further analysis in ETSI TR 102 863 i.2 takes into account some additional sources. The resulting

45、list of functional groupings from this analysis is shown in Table 1. A more detailed description can be found in ETSI TR 102 863 i.2, clause A.1.
