Work Package 2

PKI Guidance Development

The primary goal of this WP is to provide practical guidance for the implementation of a Public Key Infrastructure (PKI) for C-Roads. The purpose is to assist the National Road Authorities in understanding how they can implement the proposed European C-ITS trust model3 for protecting C-ITS data.

This work package addresses the research need “Roll-out of PKI systems” and the associated expected output, as raised in the DoRN:

• Review of the current stake of PKI roll-out in European NRAs (State of the art)
• Analysis of the issues and problems that NRAs will encounter when developing PKI infrastructure.
• Advice for building the organisations required to run a nationwide PKI infrastructure that is interoperable with Europe, and advice on outsourcing PKI services.
• Lessons from other industries (finance, healthcare, etc.) on operation of a PKI infrastructure.
• Lessons from other industries (license plate registry, etc.) on governing of identities.
• Guidance on the use of role-based and identity-based PKI.
• Analysis resources required to run C-Roads PKI infrastructure, including how the cost and computational requirements scale, and the administration required for certificate and key management.
• View of commercial and public organisations offering X.1609 PKI functionality.
• Advice for developing PKI systems that provide trust across multiple parties, for example extending the trust infrastructure to road workers or maintenance companies.
• Project partner SINTEF will perform all the work in this WP, with updates to partners Traficon and TML in order to align WP3 and WP4 with WP2.
