KIRAS Security Research

Cooperative Intelligent Transport Systems (C-ITS) aim to enable their participants to use traffic systems more efficiently and securely by providing comprehensive information and innovative services. The project “Efficient right of way for emergency vehicles in automated traffic (EVE)” considers reliable interaction of traffic control signals with connected cars, both in urban and interurban areas and in mixed-conventional-connected traffic as well as connected-traffic-only situations.

The project sets out to specify existing definitions of C-ITS Service Specific Permissions for user groups such as emergency services and public transport systems. By considering various user groups, use cases of different priorities need to be reflected by the C-ITS infrastructure system.

Example scenarios include automated right of way for emergency vehicles or virtual corridors for certain classes of traffic. The use case analysis of the traffic infrastructure’s expected behaviour for different user groups yields vital requirements for the C-ITS infrastructure. One use case is also implemented as a prototype.

EVE develops a Lifecycle Management process and works out procedures to securely handle Service Specific Permissions in phases such as issuing, regular use, revocation, and decommissioning, based on a public key infrastructure. Key aspects include reliable management of permissions, real-life use, and a comprehensive cyber-security threat analysis with resulting security levels.
