— Communication messages in vehicular ad hoc networks (VANET) can be used to locate and track vehicles. While tracking can be beneficial for vehicle navigation, it can also lead to threats on location privacy of vehicle user. In this paper, we address the problem of mitigating unauthorized tracking of vehicles based on their broadcast communications, to(More)
Cryptography Protocols Number theory Elections Secret ballot Mixnets a b s t r a c t Electronic voting is an emerging social application of cryptographic protocols. A vast amount of literature on electronic voting has been developed over the last two decades. In this paper, we provide a framework that classifies these approaches and defines a set of metrics(More)
— In vehicular ad hoc networks (VANET), it is possible to locate and track a vehicle based on its transmissions, during communication with other vehicles or the roadside infrastructure. This type of tracking leads to threats on the location privacy of the vehicle's user. In this paper, we study the problem of providing location privacy in VANET by allowing(More)
In wireless networks, the location tracking of devices and vehicles (nodes) based on their identifiable and locatable broadcasts, presents potential threats to the location privacy of their users. While the tracking of nodes can be mitigated to an extent by updating their identifiers to decorrelate their traversed locations, such an approach is still(More)
— Commercial aviation is at the threshold of the era of the e-enabled airplane, brought about by the convergence of rapidly expanding worldwide data communication infrastruc-tures, network-centric information processing and commoditized lightweight computational hardware. With advanced avionics, processing and wireless communication capabilities, the(More)
Energy efficiency, noise and emissions footprint reduction are major “green” performance targets of next-generation air transportation systems. Automatic Dependent Surveillance Broadcast (ADS-B) is an advanced “cyber-physical” concept that can help meet such targets by enabling highly accurate air traffic surveillance. However,(More)
[Abstract] The numerous benefits of enabling commercial airplanes to communicate over networks are only obtained at the price of introducing security threats to onboard systems. A primary threat arises from the opportunity for corruption of safety-critical and business-critical airplane loadable software distributed via networks from off-board systems. The(More)
