Assessing the Competing Characteristics of Privacy and Safety within Vehicular Ad Hoc Networks
Abstract
The introduction of Vehicle-to-Vehicle (V2V) communication has the promise of decreasing vehicle collisions, congestion, and emissions. However, this technology will place safety and privacy at odds. The NHTSA has proposed the SCMS as the back end infrastructure for maintaining, distributing, and revoking vehicle certificates attached to every BSM. This Public Key Infrastructure (PKI) scheme is designed around the philosophy of maintaining user privacy through the separation of functions to prevent any one subcomponent from identifying users. However, because of the high precision of the data elements within each message this design cannot prevent large scale third-party BSM collection and pseudonym linking resulting in privacy loss. In response to this difficulty, this document illustrates the fundamental tension between privacy and safety and proposes a data ambiguity method to bridge these concepts within the context of interconnected vehicles. The objective in doing so is to preserve both V2V safety applications and consumer privacy. A VANET Metric Classification is introduced that explores five fundamental pillars of VANETs.
