Secure communication with identities for connected vehicles

Common Criteria certified PKI platform

Smart ID Certificate Manager (CM) and Nexus OCSP Responder have been certified in compliance with Common Criteria EAL4+.

For more information, see Common Criteria certification

Nexus' solution for protecting vehicle-to-everything (V2X, Car2X) communication with PKI certificates is high-performing, compliant with common standards and proven in large-scale applications. V2X communication involves the passing of information from a vehicle to other entities, such as other vehicles, road infrastructure and road safety applications

Use cases 

There are numerous use cases for vehicle-to-everything (V2X) communication, for example: 

  • Road safety applications by providing warning signals to the driver.
    Warnings include forward collision, lane change, emergency brake, intersection movement assistance, emergency vehicle approach, roadworks, traffic lights and speed limits 
  • Better road utilization and saved fuel costs by platooning.
  • Autonomous driving, which is only starting to emerge and will heavily increase in the future.
