A privacy aware and efficient security infrastructure for vehicular ad hoc networks

Abstract

Abstract. VANETs have the potential to dramatically increase road safety by giving drivers more time to react adequately to dangerous situations. To prevent abuse of VANETs, a security infrastructure is needed that ensures security requirements like message integrity, confidentiality, and availability. After giving more details on the requirements we propose a security infrastructure that uses asymmetric as well as symmetric cryptography and tamper resistant hardware. While fulfilling the requirements, our proposal is especially designed to protect privacy of the VANET users and proves to be very efficient in terms of computational needs and bandwidth overhead.

Anonymous Authentication Protocols for Vehicular Ad Hoc Networks: An Overview

“…The need for confidentiality in specific scenarios of VANET implementations has also been discussed in recent works Kamat et al (2006); Li et al (2008); Plöβl & Federrath (2008); Wang et al (2008). Specifically in Wang et al (2008), the protocols of Raya & Hubaux (2007) are extended: session keys for pairs of vehicles are established by using the Diffie-Hellman key agreement protocol while group session keys are established using the key transfer approach.…”

“…Confidentiality Kamat et al (2006); Li et al (2008); Plöβl & Federrath (2008); Wang et al (2008) Some research teams pointed out that the privacy of the communication content should be protected against unauthorized observers. While confidentiality of communicating message can be negligible in most cases, it is e.g.…”

“…Besides application data administrative messages like routing protocol information or messages containing cryptographic material, the cryptographic information held by participants or centralized instances should also be protected against unauthorized access. Lin et al (2007;2008a;b); ; Mak et al (2005); Plöβl & Federrath (2008); Raya & Hubaux (2005;2007); 2010a;b); Wasef et al (2010); Wang et al (2008); Wu et al (2010); Xu et al (2007); Xi et al (2007;2008) ;Xiong et al (2010a;b); Zhang et al (2008a;b), the security system should include at least three types of entities: the top Trusted authority (TA), the immobile RSUs at the roadside, and the moving vehicles equipped with on-board units (OBUs).…”

Obviously, any malicious behaviors of user, such as injecting beacons with false information, modifying and replaying the previously disseminated messages, could be fatal to the other users.…”

Analysis of embedded CORBA middleware performance on urban distributed transportation equipments

“…Modern Intelligent Transportation Systems (ITS) equipments are based on embedded processors able to run complex computational tasks and provided with multithreading and networking capabilities. Consequently, they can expand their typical functionality to offer distributed services both to the traffic control centers and to citizens [2]. The final aim consists of transforming urban environments into smart urban environments, that is, "a small world where all kinds of smart devices are continuously working to make inhabitants' lives more comfortable" [1].…”
