Improving unlinkability in C-ITS: a methodology for optimal obfuscation. (arXiv:2301.04130v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
In this paper, we develop a new methodology to provide high assurance about
privacy in Cooperative Intelligent Transport Systems (C-ITS). Our focus lies on
vehicle-to-everything (V2X) communications enabled by Cooperative Awareness
Basic Service. Our research motivation is developed based on the analysis of
unlinkability provision methods indicating a gap. To address this, we propose a
Hidden Markov Model (HMM) to express unlinkability for the situation where two
cars are communicating with a Roadside Unit (RSU) using Cooperative Awareness
Messages (CAMs). …
