BS EN ISO 24534-4:2010+A1:2019

What is ISO 24534-4 - Electronic registration identification (ERI) about?  

ISO 24534-4 provides requirements for electronic registration identification (ERI) that are based on an identifier assigned to a vehicle 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  
• Adaptation of vehicle data  
• Safety-related purposes 
• Crime reduction 
• Commercial services 

ISO 24534-4 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 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 1: The onboard device containing the ERI data is called the electronic registration tag (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. 

Who is ISO 24534-4 - Electronic registration identification (ERI) for? 

ISO 24534-4 on Automatic vehicle and equipment identification is useful for: 

• Vehicle manufacturing companies 
• Vehicles maintenance yard 
• Commercial transport services 
• Electronic vehicle manufacturers 
• Manufacturers of EV equipment 

Why should you use ISO 24534-4 - Electronic registration identification (ERI)?  

ERI is a means of uniquely identifying road vehicles. A quickly emerging need has been identified with administrations to improve the unique identification of vehicles for a variety of services. Situations are already occurring where manufacturers intend to fit lifetime tags to vehicles. Various governments are considering the needs and benefits of electronic registration identification (ERI) as a legal proof of vehicle identity with potential mandatory uses. There is commercial and economic justification in respect of both tags and infrastructure that a standard enables an interoperable solution. 

ISO 24534-4 facilitate resale of vehicles, as the ERI interface includes provisions for another accredited registration authority to take over the registration of a vehicle. 

ISO 24534-4 supports different levels of security with maximum compatibility that helps to protect users' private data. The application of ERI will offer significant benefits over existing techniques for vehicle identification.
