Technical Limitations, and Privacy Shortcomings of the Vehicle-to-Vehicle Communication

02 november 2016

VEHICULAR 2016 : The Fifth International Conference on Advances in Vehicular Systems, Technologies and Applications

A deployment of the Vehicle-to-Vehicle communication technology according to ETSI is in preparation in Europe. Currently, a Public Key Infrastructure policy for Intelligent
Transport Systems in Europe is in discussion to enable V2V communication. This policy set aside two classes of keys and certificates for ITS vehicle stations: long term authentication keys
and pseudonymous keys and certificates. We show that from our point of view the periodic sent Cooperative Awareness Messages with extensive data have technical limitations and together with
the pseudonym concept cause privacy problems.
