In this paper, we introduce an efficient conditional privacy preservation (ECPP) protocol in vehicular ad hoc networks (VANETs) to address the issue on anonymous authentication for safety messages with authority traceability. The proposed protocol is characterized by the generation of on-the-fly short-time anonymous keys between on-board units (OBUs) and roadside units (RSUs), which can provide fast...
In this paper, we present a novel anonymous secure routing protocol for mobile ad hoc networks (MANETs). The proposed protocol not only provides anonymity from all the intermediate nodes, but also integrates the authenticated key exchange mechanisms into the routing algorithm design. Furthermore, a new attack on anonymous services, called snare attack, is introduced, where a compromised node lures...
