Providing VANET security through active position detection

Abstract

Vehicle position is one of the most valuable pieces of information in a Vehicular Adhoc NETwork (VANET). The main contribution of this work is a novel approach to enhancing position security in VANETs. We achieve local security by enlisting the help of on-board radar to detect neighboring vehicles and to confirm their announced coordinates. Local security is extended to achieve global security by using preset position-based groups to create a communication network and by using a dynamic challenging mechanism to confirm remote position information. Our solution is predicated on the widely accepted assumption that the vast majority of vehicles are honest and behave responsively. Extensive simulations confirm the quality of the proposed solution by measuring how fast compromised vehicles can be detected under various conditions.

Software-Defined IDS for securing embedded mobile devices

“…An alternative approach, collectively called location security, relies on physics and computational geometry to confirm whether a transmission originates in the trusted zone bounded by the building site, or from outside of the site (and thus from an adversary) via a strong transmitter. These techniques utilize trilateration [21], signal strength analysis from multiple receptors [34], the differing speeds of radio waves and ultrasound in atmosphere [28], onboard radar [36], and Euclidean geometry of the physical network topology [12], among other physical indicators.…”

Efficient Detection of Sybil attack Based on Cryptography in Vanet

“…This technique, can be used to detect Sybil attack discussed in [5,8]. This method is based on finding the physical location of nodes and comparing it with the vehicle's position is to claim .…”

Situation-aware trust architecture for vehicular networks

“…RLBT is a map showing the relative locations of cars in vicinity (e.g., in-front-of or following cars, left or right lanes). Existing work has studied obtaining and validating accurate relative locations [5,22]. Situations of a short period of GPS outrage are also studied through relative positioning and dead-reckoning systems [9,18].…”
