Security Infrastructure for Connected Vehicles

Microsec provides a Public Key Infrastructure (PKI) security framework to provide robust Vehicle-to-Everything (V2X) communications supporting road user safety, traffic efficiency, and automated driving in conjunction with connected vehicles and smart transportation in Europe and North America. The PKI issues and manages digital certificates that maintain integrity and ensure authenticity of messages, as well as the privacy of the sender.

Microsec V2X PKI is a security framework for providing the safety of vehicle-to-everything communication. In such environments, public key infrastructures are used to secure the environment by verifying the participants’ permissions with the usage of certificates. V2X PKI does this with the most up-to-date cryptographic solutions, including Elliptic Curve Cryptography (ECC) which has more advantages than the widely used legacy RSA algorithm. Certificates are used in order to prevent unauthorized parties from interfering with the exchange of data, and in order to pseudonymize the communication in a secure way. The hierarchy and mechanism of V2X PKI in a few words is the following:

  • On top, there is a RootCA, that will issue certificates for two other authorities, the Enrolment Authority (EA) and the Authorization Authority (AA).
  • The Enrolment Authority’s main task is to authenticate the car’s On-Board Unit canonical ID or certificate. If everything is in order, it issues a so-called Enrollment Credential (EC).
  • The ECs are required by the AAs to issue Authorization Tickets which guarantee the pseudonymity of certificates as described in the standards.
Microsec is supporting customers and establishing partnerships through participation in evaluation as well as pilot and deployment projects. Our team is eager to engage you and better understand your needs or explore how we can collaborate. You may also meet us in various forums including ETSI, C2C-CC, 5GAA, and at ETSI PlugtestsTM and OmniAir Plugfest events across the EU and the US.
