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

ISO 24534-4:2010 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.

ISO 24534-4:2010 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.

ISO 24534-4:2010 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.
