This part of ISO24534 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 ISO24534 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.
NOTE1 The onboard device containing the ERI data is called the electronic registration tag (ERT).
This part of ISO24534 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.
NOTE2 The vehicle identifiers and possible additional vehicle data (as typically contained in vehicle registration certificates) are defined in ISO24534-3.
NOTE3 The secure application layer interfaces for the exchange of ERI data with an ERI reader or writer are specified in both this part of ISO24534 and ISO24534-5.
