An Anonymous Communication Scheme with Non-reputation for Vehicular Ad Hoc Networks
Vehicular Ad hoc Network (VANET) is a kind of open wireless communication network and uses 802.11p protocol to interconnect vehicles and provides numerous services. Although it brings many of convenient applications but unlike traditionally wired networks are protected by several defenses such as firewalls and gateways, it may face a variety of security challenges such as security and privacy. The users need anonymous mechanisms to enable unlink ability but impartial third party requests non-reputation for accidents or certain events. In brief, the privacy preserving and non-reputation are contradictory. To overcome these flaws, an anonymous communication scheme with non-reputation for vehicular ad hoc networks is proposed. Our proposed scheme not only accomplishes anonymously communication between vehicle-to-vehicle and vehicle-to-roadside infrastructure for protecting privacy, but also achieves non-reputation function for identifying vehicle.
