scope:

This part of ISO/TS 24534 provides the requirements for an Electronic Registration Identification (ERI) that is based on an identifier assigned to a vehicle (e.g. for recognition by national authorities) suitable to be used for: . electronic identification of local and foreign vehicles by national authorities, . vehicle manufacturing, in-life-maintenance and end-of-life identification (vehicle life cycle management), . adaptation of vehicle data, e.g. in case of international re-sales, . safety-related purposes, . crime reduction, and . commercial services. It adheres to privacy and data protection regulations. This part of ISO/TS 24534 specifies the interfaces for a secure exchange of data between an ERT and an ERI reader or ERI writer in or outside the vehicle using asymmetric encryption techniques. NOTE 1 The onboard device containing the ERI data is called the Electronic Registration Tag (ERT). This Technical Specification includes: . the application layer interface between an ERT and an onboard ERI reader or writer, . the application layer interface between the onboard ERI equipment and external ERI readers and writers, and . security issues related to the communication with the ERT. NOTE 2 The vehicle identifiers and possible additional vehicle data (as typically contained in vehicle registration certificates) are defined in ISO/TS 24534-3. NOTE 3 The secure application layer interfaces for the exchange of ERI data with an ERI reader or writer are specified in ISO/TS 24534-4 and a future ISO/TS 24534-5.
