“…According to [13], to revoke a vehicle, the CRL is issued by a certification authority and broadcasted. Furthermore, in [14], the CRL is generated and distributed in a decentralized way; in [15], the rekeying process is also operated by a decentralized method. While the communication and computation overheads are reduced, and the delay in updating the CRL and keys decreased with these schemes, there is no procedure in V2V transmission for checking other party vehicles, and the integrity of the key.…”

In this paper, we propose a novel algorithm for reducing the size of certificate revocation lists (CRLs) created and distributed for IEEE 802.11s-based Smart Grid Advanced Metering Infrastructure (AMI) networks. Rather than maintaining a huge-size single CRL that introduces unnecessary search time and storage, the idea is to generate groups of smart meters (SMs) within the AMI network and create CRLs based on these groups. Creating groups is appropriate in AMI networks since the SMs are stationary in contrary to traditional mobile wireless networks. Our proposed grouping algorithm is based on the created paths from leaf SMs to the gateway as well as the immediate neighborhood of each SM. Via grouping, the length of the CRL for each SM and the corresponding distribution overhead can be reduced significantly. Simulation results have shown that our approach can maintain a balance between the size of the CRL and the number of signatures generated by certification authorities (CAs) while guaranteeing security of the communications.

“…To do so, the number of accusing neighbor users must exceed a threshold. A similar mechanism based also on vehicle voting is proposed in [34]. Again, by means of a voting scheme, a vehicle can be marked as misbehaving and then be revoked by its neighbors.…”

Abstract. Certificate revocation is a challenging task, especially in mobile network environments such as vehicular ad Hoc networks (VANETs). According to the IEEE 1609.2 security standard for VANETs, public key infrastructure (PKI) will provide this functionality by means of certificate revocation lists (CRLs). When a certificate authority (CA) needs to revoke a certificate, it globally distributes CRLs. Transmitting these lists pose a problem as they require high update frequencies and a lot of bandwidth. In this article, we propose BECSI, a Bandwidth Efficient Certificate Status Information mechanism to efficiently distribute certificate status information (CSI) in VANETs. By means of Merkle hash trees (MHT), BECSI allows to retrieve authenticated CSI not only from the infrastructure but also from vehicles acting as mobile repositories. Since these MHTs are significantly smaller than the CRLs, BECSI reduces the load on the CSI repositories and improves the response time for the vehicles. Additionally, BECSI improves the freshness of the CSI by combining the use of delta-CRLs with MHTs. Thus, vehicles that have cached the most current CRL can download delta-CRLs to have a complete list of revoked certificates. Once a vehicle has the whole list of revoked certificates, it can act as mobile repository.
