AutoCrypt PKI

Public Key Infrastructure for V2X

Protecting all vehicle connections with a PKI-based security module

AutoCrypt PKI is a specialized public key infrastructure for V2X, providing certificate-based authentication for OBUs and RSUs in compliance with IEEE 1609.2, and revokes existing certificates based on detected misbehavior.

AutoCrypt PKI complies with CAMP, USDOT SCMS and CCMS (Cooperative ITS Credential Management System).

AutoCrypt PKI is a crucial component of AutoCrypt V2X, AutoCrypt PnC, and is utilized across a wide range of vehicle connections including the digital key.

The Basics of PKI

AutoCrypt PKI issues both enrolment certificates and authorization certificates to OBUs and RSUs.

Enrolment certificates are issued when the units are first registered, while authorization certificates are issued every time before a basic safety message (BSM) is sent. Authorization certificates are further broken down into pseudonym certificates (for vehicle identification), identification certificates (for infrastructure), and application certificates (for OBUs). These certificates act as IDs that prove the identity of the entity and the legitimacy of the messages.
