An Efficient Pseudonymous Authentication Scheme with Strong Privacy Preservation for Vehicular Communications
2010Co-Authors: Yipin Sun, Xiaodong Lin, Student Member, Xuemin ShenAbstract:Abstract—In this paper, we propose an efficient pseudonymous authentication scheme with strong privacy preservation, named PASS, for vehicular communications. Unlike traditional pseudonymous authentication schemes, the size of Certificate Revocation List (CRL) in PASS is linear with the number of revoked vehicles and irrelated to how many pseudonymous Certificates are held by the revoked vehicles. PASS supports Roadside Unitsaided distributed Certificate Service that allows the vehicles to update Certificates on road, but the Service overhead is almost irrelated to the number of the updated Certificates. Furthermore, PASS provides strong privacy preservation to the vehicles so that the adversaries can not trace any vehicle even all Roadside Units have been compromised. Extensive simulations demonstrate that PASS outperforms previously reported ones in terms of the revocation cost and the Certificate updating overhead.

nehcm a novel and efficient hash chain based Certificate management scheme for vehicular communications
International ICST Conference on Communications and Networking in China, 2010Co-Authors: Yipin Sun, Xiaodong Lin, Xuemin ShenAbstract:In this paper, we propose a Novel and Efficient Hash-chain based Certificate Management (NEHCM) scheme for vehicular communications. In NEHCM, to protect driver privacy, each vehicle is equipped with a large set of short-time Certificates, and most importantly, serial numbers of these Certificates satisfy hash-chain relationship. As a result, the Certificate revocation becomes an easy task by simply releasing two hash chain seeds. However, without knowing the seeds, it is infeasible to reveal the linkability among these Certificates. Thus, not only vehicles can obtain enough Certificates for privacy preservation, but also the size of Certificate Revocation List (CRL) remains linear to the number of revoked vehicles, irrelative to the large number of revoked Certificates in NEHCM. Furthermore, NEHCM adopts Roadside Units (RSUs) aided Certificate Service architecture, but the Service overhead for an RSU is very low and irrelated to the number of the updated Certificates. Extensive simulations demonstrate that the proposed scheme outperforms previously reported works in terms of the revocation cost.

IEEE Transactions on Vehicular Technology, 2010Co-Authors: Yipin Sun, Xiaodong Lin, Xuemin ShenAbstract:In this paper, we propose an efficient pseudonymous authentication scheme with strong privacy preservation (PASS), for vehicular communications. Unlike traditional pseudonymous authentication schemes, the size of the Certificate revocation list (CRL) in PASS is linear with the number of revoked vehicles and unrelated to how many pseudonymous Certificates are held by the revoked vehicles. PASS supports the roadside unit (RSU)-aided distributed Certificate Service that allows the vehicles to update Certificates on road, but the Service overhead is almost unrelated to the number of updated Certificates.

DCS: An Efficient Distributed-Certificate-Service Scheme for Vehicular Networks
IEEE Transactions on Vehicular Technology, 2010Co-Authors: Albert Wasef, Yixin Jiang, Xuemin ShenAbstract:In this paper, we propose an efficient distributed-Certificate-Service (DCS) scheme for vehicular networks. The proposed scheme offers flexible interoperability for Certificate Service in heterogeneous administrative authorities and an efficient way for any onboard units (OBUs) to update its Certificate from the available infrastructure roadside units (RSUs) in a timely manner. In addition, the DCS scheme introduces an aggregate batch-verification technique for authenticating Certificate-based signatures, which significantly decreases the verification overhead. Security analysis and performance evaluation demonstrate that the DCS scheme can reduce the complexity of Certificate management and achieve excellent security and efficiency for vehicular communications.

secure and efficient key management in mobile ad hoc networks
Journal of Network and Computer Applications, 2007Co-Authors: Eduardo B Fernandez, Mohammad Ilyas, Spyros S MagliverasAbstract:In mobile ad hoc networks, due to unreliable wireless media, host mobility and lack of infrastructure, providing secure communications is a big challenge. Usually, cryptographic techniques are used for secure communications in wired and wireless networks. Symmetric and asymmetric cryptography have their advantages and disadvantages. In fact, any cryptographic means is ineffective if its key management is weak. Key management is also a central aspect for security in mobile ad hoc networks. In mobile ad hoc networks, the computational load and complexity for key management are strongly subject to restriction by the node's available resources and the dynamic nature of network topology. We propose a secure and efficient key management (SEKM) framework for mobile ad hoc networks. SEKM builds a public key infrastructure (PKI) by applying a secret sharing scheme and using an underlying multi-cast server groups. We give detailed information on the formation and maintenance of the server groups. In SEKM, each server group creates a view of the Certificate authority (CA) and provides Certificate update Service for all nodes, including the servers themselves. A ticket scheme is introduced for efficient Certificate Service. In addition, an efficient server group updating scheme is proposed. The performance of SEKM is evaluated through simulation.
