Trusted Integrity and Authenticity for Road Applications (TIARA)

From 2024 to 2025
The TIARA project helps national road authorities set up a reliable and secure data infrastructure for new business models, while ensuring privacy. TML supports the consortium with investigating privacy issues and offers recommendations for transparency and trust in data use.
The TIARA project (Trusted Integrity and Authenticity for Road Applications) aims to give National Road Authorities or NRAs a better understanding of what is needed to achieve a reliable and secure data infrastructure. Available data allows road users and NRAs to benefit from new business models, but to provide these benefits, the data infrastructure must be reliable and trusted - i.e., secure - with the guarantee that the privacy of all stakeholders is safeguarded.
Since the inception of the C-Roads Platform, several ITS programmes have been rolled out and it was observed that NRAs need to understand some key moments before implementing these systems on a larger scale. The TIARA project is designed to address the two key areas of trust and privacy in C-ITS applications. The first topic, trust, concerns understanding how to implement trust models that can protect C-ITS data. The second topic, privacy, concerns understanding the impact of user personal data processed, including location. Three broad research areas have been identified:
TML supports the consortium in exploring all relevant privacy issues with practical recommendations on transparency and trust around data use by road users and operators, ensuring both lawful and responsible behaviour. This involves openness of primary and secondary use of all types of data, information, patterns, and characteristics that can be traced back to road users and therefore need to be protected.

The second topic, privacy, concerns understanding the impact of user personal data processed, including location. Three broad research areas have been identified:
- Trust in C-ITS applications to develop practical guidance for implementing public key infrastructure (PKI) for C-Roads.
- Legal and ethical implications for NRAs when using C-ITS data, and how these change the role of NRAs .
- Privacy impact of road users' processed location data and recommendations to improve the preservation of location privacy for NRAs .
