ISO 24534-1:2010 自動車両および機器識別—車両の電子登録識別（ERI）—パート1：アーキテクチャ | ページ 5

2.1

additional vehicle data

ERI data in addition to the vehicle identifier

2.2

air interface

conductor-free medium between onboard ERI equipment and the reader/interrogator through which the linking of the onboard equipment to the reader/interrogator is achieved by means of electro-magnetic signals

[SOURCE:ISO 14814:2006, definition 3.2]

2.3

back office

facility for the control and data management of an ERI system by an authority, or for the provision of related services by a service provider

2.4

confidentiality

property that information is not made available or disclosed to unauthorized individuals, entities, or processes

[SOURCE:ISO 7498-2:1989, definition 3.3.16]

2.5

electronic registration identification

ERI

action or act of identifying a vehicle with electronic means for purposes described in the scope of this part of ISO 24534

2.6

ERI data

vehicle identifying data which can be obtained from an ERT

Note 1 to entry: ERI data consists of the vehicle identifier and possible additional vehicle data.

2.7

electronic registration reader

ERR

device used to read or read/write data from or to an ERT

2.8

electronic registration tag

ERT

onboard ERI device that contains the ERI data, including relevant security provisions and one or more interfaces to access data

Note 1 to entry: In cases of high security, the ERT is a type of SAM (secure application module).

Note 2 to entry: The ERT may be a separate device or may be integrated into an onboard device that also provides other capabilities (e.g. DSRC communications).

2.9

key

sequence of symbols that controls the operations of a cryptographic transformation (e.g. encipherment, decipherment, cryptographic check function computation, signature generation, or signature verification)

[SOURCE:ISO/IEC 9798-1:1997, definition 3.3.13]

Note 1 to entry: See ISO/IEC 9798-1 for the meaning of the terms used for the examples of cryptographic transformations.

2.10

onboard ERI equipment

equipment fitted within or on the outside of the vehicle and used for ERI purposes

Note 1 to entry: The onboard equipment includes the ERT and any communication provisions for the exchange of ERI data with an ERI reader or writer.

2.11

registration authority

authority responsible for the registration and maintenance of vehicle records

Note 1 to entry: The authority can provide vehicle records to accredited organizations.

2.12

registration authority

organization responsible for the ERI data and security data according to local legislation

Note 1 to entry: The registration authority for ERI data can be the same as the registration authority for vehicles. This part of ISO 24534, however, does not require this.

2.13

security

protection of information and data so that unauthorized persons or systems cannot read or modify them and authorized persons or systems are not denied access

[SOURCE:ISO/IEC 12207:2008, definition 4.39]

2.14

specific vehicle identification

action or act of establishing the identity of a specific vehicle

Note 1 to entry: This is in contrast to vehicle vicinity identification ここで, the vicinity of a vehicle with a specific identity is detected. With specific vehicle identification, it is also known which specific vehicle has been identified.

Note 2 to entry: Two kinds of specific vehicle identification may be distinguished: first, localized vehicle identification, in which case the location of the identified vehicle is known with such precision that not more than one vehicle can be present at the same time at that location; second, peer communication identification, in which case the identification of the vehicle engaged in some form of communication (e.g. an EFC transaction) is established.

2.15

vehicle identification

action or act of establishing the identity of a vehicle

Note 1 to entry: For the purposes of this part of ISO 24534, a distinction is made between specific vehicle identification and vehicle vicinity identification.

2.16

vehicle vicinity identification

action or act of establishing the identity of a specific vehicle near an external ERI reader (ERR) without pinpointing the exact position of the vehicle

Note 1 to entry: If there is more than one vehicle present in the vicinity of a reader, no specific vehicle, or its exact location, is identified. However, it will establish that a specific vehicle identity has passed in the vicinity of a reader.
