ÖNORM EN ISO 24534-4

This part of ISO 24534 provides requirements for electronic registration identification (ERI) that are 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. for international resales); - safety-related purposes; - crime reduction; - commercial services. It adheres to privacy and data protection regulations. This part of ISO 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 part of ISO 24534 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; - 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 24534-3. NOTE 3 The secure application layer interfaces for the exchange of ERI data with an ERI reader or writer are specified in both this part of ISO 24534 and ISO 24534-5.
