“…However, a bilinear pairing operation is used here to create the group certificates and public key, which adds complex processing to memory-constrained devices in vehicular ad hoc networks. The cost of one pairing operation is three times greater than that of a one-point multiplication operation [3]. Thus, the pairing operation adds an additional burden, increasing the processing time and memory requirements of the entities of the network.…”

“…Figure 1 expresses the general architecture of the VANET environment. According to a survey [3], by the end of 2027, almost 100% of vehicles will be equipped with OBUs. The medium through which these elements in the network communicate with each other is either through dedicated short-range communication (DSRC) or wireless access for the vehicular environment (WAVE).…”

“…The medium through which these elements in the network communicate with each other is either through dedicated short-range communication (DSRC) or wireless access for the vehicular environment (WAVE). Transport will eventually increase by 35% per decade in the upcoming three decades [3]. In a large-scale deployed network, with the challenge of open environment access, secure communication plays a very important role in terms of preserving vehicle privacy and maintaining message integrity.…”

The rapid expansion in research has led to vast interest in intelligent transport systems (ITSs), especially vehicular ad hoc networks (VANETs), which include communication among smart vehicles by using built-in sensors. Authorizing these vehicles and preserving their privacy while sharing messages play an important role in secured data transmission. Messages should be signed by vehicles and verified between legitimate entities to establish trust and decrease security risks. Traditional protocols operate in a centralized mode, where a trusted authority (TA) is tasked with authorizing secure communication between vehicles and bears the computational costs for the security operations for every entity in a VANET. Lightweight and secure solutions are important to ensure the advancement of wireless communication by preventing malicious users. This article presents a lightweight privacy-preserving signature-based authentication (LPPSA) protocol that solves the limitations of state-of-the-art protocols while reducing the computational burden on a TA. The proposed LPPSA protocol takes advantage of the short elliptic curve cryptography (ECC) parameters and leverages the Diffie-Hellman key exchange algorithm to generate shared secret keys. The roadside unit (RSU) plays a major role in assisting this authentication process and helps in reducing the overall computational complexity of a TA. The RSU provides lightweight secure authentication along with malicious vehicle revocation. The performance analysis and comparison with similar protocols show that the proposed LPPSA is more efficient, as it reduces the security risks and lowers the computational complexity of the overall system.

Secure and reliable routing expands the performance of wireless communication infrastructure of the Advanced Metering Infrastructure (AMI).This paper tries to deliver reliable routing using combination of AODV(Reactive type protocol) and DSDV(proactive type protocol) protocol considering WSN. Different kinds of Attack annoys the enactment of communication infrastructure of AMI. This paper defends communication infrastructure from DoS (Denial of service) attack. The main aim of this paper try to provide reliable routing with security. Communication infrastructure is a key element of AMI. Providing reliability and security for communication infrastructure we can improve the performance of AMI. Due to this electricity sector can save millions of dollars and we provide social awareness about importance of electricity security or Smart Grid. This paper calculates the security in terms of delay, energy consumption, throughput, PDR (Packet Delivery Ratio) and overhead. By considering these parameters we will calculate Confidentiality, Integrity, Availability and Accountability (non- repudiation). Wireless Sensor Network (WSN) considered for wireless communication infrastructure for the AMI. Sensor nodes are battered for attack. Intended for AODSD2V2 (Ad Hoc on Demand Destination Sequenced Distance Vector Routing Protocol) protects the data packets from malicious nodes and DoS attack. For the WSN network infrastructure two kinds of topologies are considered 1. Random deployment strategy 2. Grid deployment. Network Simulator2 (NS2) delivers comparatively simulation results intended for the calculation of reliability and security.

“…VCs have been classified in three classes as function of their scale, infrastructure support and communication sensitivity [30]: (a) Safe mobility: contains safety‐of‐life communications to notify drivers of dangerous situations. Such applications are localised, and are very sensitive to transmission impairments, delay and loss.…”
