Security services for eSafety applications clusters

The high number of applications envisioned for VANETs and the diversity of their characteristics (time constraints, communication mode, etc.) form a challenge for the development of the adequate secure system. Clustering them into homogeneous groups can constitute a start point for the designing of the suitable communication and security components. In this work, we propose seven eSafety application clusters based on communication criteria having an impact on security mechanisms to be implemented. Then we highlight security services required for each cluster.
