Automatic vehicle and equipment identification — Electronic Registration Identification (ERI) for vehicles — Part 4: Secure communications using asymmetrical techniques

ISO TS 24534-4:2008 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) and 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.

ISO TS 24534-4:2008 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. It includes:

• the application layer interface between an ERT and a 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.
