Obtaining efficient security without compromising privacy is a primary issue in vehicular communication. Though many counterparts proposed solutions in this regard, accommodating scalability, security and traceability altogether is a difficult task due to the contradictions between these qualities. Some of the previous studies suggests RSU based authentication to address the above issues, while others propose independent OBU authentication. In either scheme, any one of the entities is overloaded during key generation and verification processes. The proposed scheme addresses these issues, by distributing the workload between OBUs and RSUs to outperform other protocols. We propose a novel scheme, in which OBUs generate short-lived public keys on the fly and other vehicles can verify them with the help of RSUs. This protocol also admits certificate-less authentication, in addition to aggregated signature verification. Therefore, the total verification time can be drastically reduced in the proposed scheme. We analyze the proposed protocol significantly to demonstrate its efficiency.

“…Cryptographic mechanisms of the identity-based encryption [14] and the proxy signature [15] are often adapted in V2I communication scenarios. Choi et al [16] developed security mechanisms to protect vehicular communication. In the initial phase, vehicles and RSUs need to register their identities with the trust authority (TA) to capture their temporary key-related materials and private/public key pair of elliptic curve cryptography.…”

Vehicular networks are organized with high-mobility vehicles, which are a challenge to key agreement and secured communication among vehicles; hence, efficient cryptography schemes for lightweight ciphers are essential. Many security schemes for vehicular networks particularly take the secure propagation of traffic-related information into account. Group communication is desirable in vehicular networks, while groups of friends drive the vehicles to travel together. In this study, it is applied an asymmetric key mechanism and a group-based Elliptic Curve cryptograph to authenticate data propagation as also to individually secure group communication. The data propagation includes a flooding delay mechanism, where each vehicle participant in the propagation calculates an individual delay for propagation. As groups of vehicles move on the roadway toward same destinations, two alternative schemes of group key agreement in vehicle-to-vehicle and vehicle-to-infrastructure modes are proposed to secure group communication among the vehicles. Security analysis results present that the proposed schemes can effectively prevent malicious vehicle from participating in vehicular communications. Evaluation results show that the propagation delay mechanism can effectively reduce broadcast collision, and the delay results of the group key agreement schemes are acceptable.

“…Recent advances in the development of wireless vehicular networks have become a cornerstone of ITS. Security is a fundamental issue for vehicular networks since without security protection ITS communication does not work properly [5,6]. For large parking lots, through Wireless sensor networks and vehicular communication, a new smart parking scheme were proposed for providing the drivers with real-time parking navigation service, intelligent antitheft protection, and friendly parking information dissemination [7][8][9][10].…”

Operators of parking guidance and information (PGI) systems often have difficulty in providing the best car park availability information to drivers in periods of high demand. A new PGI configuration model based on the optimized combination method was proposed by analyzing of parking choice behavior. This article first describes a parking choice behavioral model incorporating drivers perceptions of waiting times at car parks based on PGI signs. This model was used to predict the influence of PGI signs on the overall performance of the traffic system. Then relationships were developed for estimating the arrival rates at car parks based on driver characteristics, car park attributes as well as the car park availability information displayed on PGI signs. A mathematical program was formulated to determine the optimal display PGI sign configuration to minimize total travel time. A genetic algorithm was used to identify solutions that significantly reduced queue lengths and total travel time compared with existing practices. These procedures were applied to an existing PGI system operating in Deqing Town and Xiuning City. Significant reductions in total travel time of parking vehicles with PGI being configured. This would reduce traffic congestion and lead to various environmental benefits.
