Abstract [en]

Inter-vehicle communications disclose rich information about vehicle whereabouts. Pseudonymous authentication secures communication while enhancing user privacy. To enhance location privacy, cryptographic mix-zones are proposed where vehicles can covertly update their credentials. But, the resilience of such schemes against linking attacks highly depends on the geometry of the mix-zones, mobility patterns, vehicle density, and arrival rates. In this poster, we propose "mix-zones everywhere",a cooperative location privacy protection scheme to mitigate linking attacks during pseudonym transition. Time-aligned pseudonyms are issued for all vehicles to facilitate synchronous pseudonym updates. Our scheme thwarts Sybil-based misbehavior, strongly maintains user privacy in the presence of honest-but-curious system entities, and is resilient against misbehaving insiders.
