PAL - privacy augmented LTE: A privacy-preserving scheme for vehicular LTE communication

We propose a novel privacy-preserving scheme for LTE in vehicular communication. The main idea behind our concept is to include original equipment manufacturers (OEM) of vehicular stations in the mobile connection's life cycle. Our scheme makes use of pseudonymous identifiers and splits the identity management for communicating vehicles between mobile network operators and OEMs. We show that our scheme improves the privacy of subscribers without loss of functionality in terms of all relevant use cases for vehicular communication over LTE.
