The increasing capabilities and decreasing cost of information and communication technologies (ICTs) are enabling new categories of vehicular telematics applications, such as wireless drive-through (WDT) services, in which an external service provider provides services to in-vehicle occupants via a wireless connection. Most telematics systems rely on proprietary protocols for data exchange between an in-vehicle client and its external counterpart in individual applications, making it difficult to share data-exchange methods among applications. Sharing dataexchange methods is important because it allows a rapid return on ICT investments. In this paper, we study the data-modeling issues for data exchange between an in-vehicle client and its service provider for WDT services. We present a novel data model that captures the main characteristics of data exchange for the WDT application family, using a formal mathematical representation and an intuitive graphical representation. We show that the proposed data model provides generality for such data exchange. In addition, we propose several optimization techniques based on the data model to minimize user interaction so that a good usability can be achieved. Our simulations and analysis demonstrate that the proposed data model and relevant optimization techniques are promising in supporting efficient WDT applications.

Security and especially privacy is an important requirement for the success of vehicular ad hoc networks (VANETs) in the future. To introduce and realize privacy a common method is to use pseudonyms to improve the unlinkability of nodes, events, and locations. Each node will own a multitude of pseudonyms and has to change them once in a while. The mobility of nodes has an important impact on the use and the change mechanism of pseudonyms in VANETs. This influence is analyzed by means of simulation and mathematical analysis. To have a simple yet solid mobility model the Manhatten Grid Mobility model was designed to model vehicle mobility. Using this model the two important parameters node re-interaction, how often and in what time intervals do nodes re-interact, and node quiet-time, how long should a node stay quiet before changing its pseudonym, are examined using simulation. In addition, an analytical method for determining the upper bound of the node quiet-time is presented. These results can mainly help to set parameters for pseudonym change protocols and estimate the impact of using these concepts in VANETs.

“…For example, a location-based service might choose to reveal that a group of users is at a specific location (such as an office), or an individual is located in a vague location (such as in a building), but would not reveal that a specific individual is located at a specific location. Duri examined the protection of telematics data by applying a set of privacy and security techniques [30].…”

Wireless sensor networks are typically deployed to measure the information field, rather than create an information field. However, by utilizing the radio on sensor nodes, it is possible to invert the role of sensor networks, and allow sensor nodes to actuate the environment. Such actuation can facilitate new forms of access control that are based on whether a user is located at the right place at the right time. In this paper, we explore the challenges of supporting spatiotemporal access control, where access to an object or service is based on the user's spatio-temporal context. Specifically, we focus on supporting spatio-temporal access control through the specification of access control policies, and show how complex spatio-temporal policies can be specified using automata. We outline a challenge-response mechanism for verifying user location in a centralized spatio-temporal access control mechanism. We utilize sensor networks in an inverted fashion to support spatio-temporal access control. Sensor nodes announce keys according to a time-varying schedule, and users may access restricted files/resources only if they are in the neighborhood of the correct sensor node and witness the appropriate cryptographic key.
