Efficient and robust pseudonymous authentication in VANET

Abstract

Effective and robust operations, as well as security and privacy are critical for the deployment of vehicular ad hoc networks (VANETs). Efficient and easy-to-manage security and privacy-enhancing mechanisms are essential for the wide-spread adoption of the VANET technology. In this paper, we are concerned with this problem; and in particular, how to achieve efficient and robust pseudonym-based authentication. We design mechanisms that reduce the security overhead for safety beaconing, and retain robustness for transportation safety, even in adverse network settings. Moreover, we show how to enhance the availability and usability of privacy-enhancing VANET mechanisms: Our proposal enables vehicle on-board units to generate their own pseudonyms, without affecting the system security.

5G-VRSec: Secure Video Reporting Service in 5G Enabled Vehicular Networks

“…The proposed scheme suggests the usage of PASS [8] as the mechanism for authentication of videos uploaded to the Cloud Platform, not only because it has one of the lowest overheads in terms of time for signing, certificate validation, and signature verification (see Table 2), but also because it solves the limitation of BP [16]. However, other algorithms such as BP [16], ECPP [17], DCS [18], and hybrid one [19] can be considered. Table 2 shows the time required for generation and verification of signatures and certificate verification using different algorithms [8] (same for both Eiza-Ni-Shi Scheme and proposed scheme).…”

RSSI-Based User Centric Anonymization for Location Privacy in Vehicular Networks

“…By incorporating HAB and GSB approaches, Calandriello [5] proposed a hybrid scheme. In this scheme, each vehicle is equipped with a group signing key and a group public key.…”

“…To solve the problem mentioned above, the authors in [2][3][4][5] proposed schemes to remove the correlation between locations and identifiers by periodically or randomly updating vehicles' pseudo identifiers. Although these methods could make vehicles unidentifiable within an anonymity set in motionless states, it can still be traced by movement tracking [6].…”

“…Because these safety messages are broadcasted wirelessly in plaintext for safety applications, they are vulnerable to eavesdropping, and the location information of the vehicles can then be extracted from either position related data or identification related data. Therefore, although the broadcast safety messages could in principle improve driving safety, unauthorized parties or attackers may exploit the vulnerabilities of these VANET application systems and compromise the location privacy of the interested vehicles [1].To solve the problem mentioned above, the authors in [2][3][4][5] proposed schemes to remove the correlation between locations and identifiers by periodically or randomly updating vehicles' pseudo identifiers.

EDR: Efficient Decentralized Revocation Protocol for Vehicular Ad Hoc Networks

“…Systems based on symmetric key cryptosystems were developed in [6]- [8] to provide security to VANETs while minimizing the overhead and increasing the encryption/decryption speeds compared with those of the PKI. In [9]- [13], the group signature technique was used to provide security and privacy to VANETs. All of the foregoing systems rely on the CRL as a revocation method without considering the special characteristics of VANETs.…”
