“…Security challenges are the critical and indispensable issues to solve in the first place in order to build realistic and practical VANET applications (Yousefi et al, 2006;Parno and Perrig, 2005;Hubaux et al, 2004;Raya et al, 2006b). The existing security research work in VANETs include Self-Organising Traffic Information System (SOTIS) (Wischhof et al, 2003), security and privacy issues (Raya and Hubaux, 2005;Papadimitratos et al, 2006aPapadimitratos et al, , 2006bHubaux et al, 2004;Plobl et al, 2006;Dotzer, 2006), fast authentication (Liu et al, 2006;Parno and Perrig, 2005), secure data aggregation (Picconi et al, 2006;Raya et al, 2006a), and detecting and correcting malicious data (Raya et al, 2006a;Golle et al, 2004), and so on. Among these security challenges, we focus on the reliable traffic information propagation through multiple vehicles.…”

Abstract:In vehicular ad hoc network, vehicles can share traffic/emergency information. The information should not be modified/manipulated during transmission without detection. We present two novel approaches to provide reliable traffic information propagation: two-directional data verification, and time-based data verification. The traffic message is sent through two (spatially or temporally spaced) channels. A recipient vehicle verifies the message integrity by checking if data received from both channels are matched. Compared with the popular public-key based security systems, the proposed approaches are much simpler and cheaper to implement, especially during the initial transition stage when a mature VANET network infrastructure does not exist.

“…Researchers have conducted many researches about selforganizing traffic information system (SOTIS) [1], security and privacy issues [2][3][4][5][6][7], fast authentication [8][9][10], secure data aggregation [11][12], and detecting and correcting malicious data [12][13] in VANET. Among these security challenges, we especially concern about reliable traffic information propagating through multiple vehicles over a relatively long distance.…”

Abstract-In a Vehicular Ad-Hoc Network (VANET), an important application is to let moving vehicles collaborate with each other by sharing traffic information and alerting others of any emergency or accidental scenarios. To make this application possible, a security mechanism must be designed in the beginning to guarantee that no malicious vehicles or persons can intercept, manipulate, or modify traffic information propagating in a VANET without being detected. In this paper, we present a novel approach to provide reliable traffic information propagation in a VANET: two-directional data verification.Two-directional data verification approach uses vehicles in both directions of a two-way road as two separated media channels to propagate traffic data. By receiving messages from both channels, a recipient vehicle verifies the message integrity by checking if data received from both channels are matched. This approach exploits the fact that it is difficult for an adversary to have two collaborative vehicles on both driving directions in the same region. Even if an adversary can do this, it is costly and attacks can be done only in a short time period. The proposed approach is simple and readily to be implemented, requiring no complicated public-key infrastructure to protect traffic information propagation in VANET.
