Security Infrastructure for Connected Vehicles

Microsec is pioneering in the development of the ecosystem of connected vehicles and road infrastructure in Europe. We offer the Public Key Infrastructure (PKI) background that provides security infrastructure (V2X certificates) for car manufacturers, vendors, roadside and onboard unit developers, transportation and smart city infrastructure operators.

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 so with the most up-to-date cryptographic solutions, including Elliptic Curve Cryptography (ECC) which has more advantages than the widely used RSA algorithm.

Certificates are used in order to prevent unauthorized parties to interfere 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 Enrolment Credential (EC). The ECs are required by the AAs to issue Authorization Tickets which guarantee the pseudonymity of certificates as described in the standards.

Ensuring Vehicles Communication

Nowadays, the topic of self-driving cars gets a lot of attention even in everyday chit-chat. Such vehicles appear more and more frequently in several countries and developing the required technology became one of the main priorities of manufacturers. There are a lot of different opinions regarding autonomous vehicles and one kind of these simply argue the safety of them, posing questions, such as „What ensures that they will not crash into each other?” and the like. The answer is - beside many others - our beloved subject: PKI. Let’s see, how.

Microsec is ready to establish partnerships and participate in pilot projects. Please find our business development and V2X PKI product team. You may also meet us at ETSI PlugtestsTM and OmniAir Plugfest events across the EU and the US.
