Black Hole Attack ii) Worm Hole attack: In this type of attack somebody receives packets at one point within the network, tunnels them to a different purpose within the network, so replays them into the network from that time. This tunnel between two adversaries referred to as wormhole. It is often established through one long-range wireless link or a wired link between the 2 adversaries. Therefore, it's easy for the somebody to form the tunneled packet arrive before different packets transmitted over a traditional multi-hop route as shown in Figure 5.

Cybersecurity is currently a topic of utmost significance in tech sectors. The ever-evolving landscape of this field makes it particularly difficult to navigate. This paper aims to help the reader understand the complexity of network attacks and also show how we may never ‘solve’ the problem of cyber attacks. Our paper may be accessible to the layman, but a basic understanding of networking fundamentals would be desirable. Computer security, cybersecurity, or information technology security may all be used interchangeably throughout the paper. An ‘attack’ will refer to a breach in security to an online system that may cause (but is not limited to) the following: unauthorized information disclosure, theft of technology, or disruption of services.Keywordscybersecuritynetworksystemattacksecurity
... They realize the temporary certificates for vehicle-to-vehicle and vehicle-to-road communications by using a combination of permanently valid authentication integers and temporary pseudonym certificates. Kumar and Arora [18] enhance the confidentiality of data in the IoV through unicast communication in V2V (Vehicle to Vehicle) mode. Wu et al. [19] put forward a new and efficient identity-based message authentication scheme. ...
Because of a large number of vehicles in Internet of Vehicle(IoV), distributed nodes and complex driving environment, data security and certification speed are easily affected. Blockchain enables different devices that do not trust each other to work together, maintain the general state in the process of information dissemination and sharing, and protect the privacy of devices. However, at present, the speed of vehicle certification in IoV is slow, and the use of idle resources is not considered. To address this problem, this paper provides a blockchain-based vehicle identity verification scheme by using a hybrid identity code verification method to ensure the nodes in the network securely share information. Meanwhile, a task processing algorithm based on time window is proposed to optimize the utilization of idle resources. In addition, the method is evaluated by simulation experiment, and the designed scheme can reduce malicious behavior of a registered vehicle in the network, and can shorten the processing task delay.

Thanks to the rapid development in mobile vehicles and wireless technologies, Internet of Vehicles (IoV) has become an attractive application that can provide a large number of mobile services for drivers. Vehicles can be informed of the mobile position, direction, speed and other real-time information of nearby vehicles to avoid traffic jams and accidents. However, the environments of IoV could be dangerous in the absence of security protections. Due to the openness and self-organization of Internet of Vehicles, there are enormous malicious attackers. To guarantee the safety of mobile services, we propose an effective decentralized authentication mechanism for Internet of Vehicles on the basis of the consensus algorithm of blockchain technology. The simulation under the Veins framework is carried out to verify the feasibility of the scheme in reducing the selfish behavior and malicious attacks in Internet of Vehicles.

Security is one of the key important factors in ad hoc network due to the open wireless medium and dynamic topology of the network. MANET, VANET and FANET are type of ad hoc network and their applications are served the end users in real environment. VANET and FANET are next generation network and due to safety applications more attractions for end users in these networks. In this paper, we will provide the survey on security issues and challenges in the field of MANET, VANET and FANET. The successful implementation of these networks in real environment, it is require the network will be secure and end user can take benefit from their life safety applications.
