term used to describe different operational component properties/specifications
right of individuals to control or influence what information related to them may be collected and stored and by whom and to whom that information may be disclosed
ability to keep in a condition of good repair or efficiency
describe different environmental component properties/specifications
condition which exists when two or more items possess such functional and physical characteristics as to be equivalent in performance and durability, and are capable of being exchanged one for the other without alteration of the items themselves, or of adjoining items, and without selection for fit and performance
property that none of the entities involved in a communication can deny in all or in part its participation in the communication
completed cycle of communication (across the air interface at reference point delta) wherein a message identifying a vehicle or item of equipment is successfully received and understood by the receiver during one passage through the read zone
NOTE The number of attempts, retries and repeats is not relevant, it is only that one fully completed identification process communication cycle is successfully completed to the extent that no communications error could be detected.
function that an application process resident at the roadside equipment can invoke in order to make the on-board equipment execute a specific operation during the transaction
entity authentication which provides both entities with assurance of each other’s identity
action or act of establishing the identity
NOTE See also vehicle identification.
process of identifying equipment or entities that uses the surface transportation infrastructures by means of OBE’s combined with the unambiguous data structure
entity authentication which provides one entity with the assurance of the other's identity but not vice versa
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 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.
unique identification of a vehicle by wireless communications between an electronic registration tag carried on a vehicle and an electronic registration reader
action or act of establishing the identity of a specific vehicle
NOTE 1 This is in contrast to vehicle vicinity identification, where 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 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.
function which maps strings of bits to fixed-length strings of bits, satisfying the following two properties: a) for a given output, it is computationally infeasible to find an input which maps to this output; and b) for a given output, it is computationally infeasible to find a second input which maps to the same output
NOTE Computational feasibility depends on the specific security requirements and environment.
decryption reversal of a corresponding reversible encipherment
encipherment of data within or at the source end system, with the corresponding decipherment occurring only within or at the destination end system
