    Opis:
    In recent years, Vehicles are becomes the more intellectual system which is operated with the help of radio communications. Thus the vehicles are formed the network for communications based on the mobile Ad- hoc network (MANET) which is called as Vehicular Ad-hoc Network (VANET). However security in Vehicular Ad-hoc Networks (VANET) should become great challenges, due to communication development, because of dynamically changing protocols, high mobility of vehicles and also high partitioned network. In this paper we address the security requirements of vehicles and needed mechanisms to avoid the threats and attacks in VANET.

    Opis:
    Applications of VANET (Vehicular ad hoc Networks) networks is focused on monitoring of the safety states of vehicles or roadway by exchanging messages between vehicles and infrastructure so that the applications will be able to help a driver to handle insecure situations. They are able to warn before possible risks which can occur during the process of transportation. Essential tool for assuring of safety communications within developed applications of intelligent transportations systems are cryptography constructions on the basis of digital signature schemes. In order to assuring safety and anonymity within vehicular communications are used pseudorandom authentications methods. The authors in the paper are focused on realization of mathematical model and description of modified cryptographic constructions which are suitable for sensor networks and applications orientated to memory and performance. In these systems it is very important to use signature scheme which do not have only computational safety but must also be effective from the view of performance and must generate short digital signatures in order to communications in real time conditions.

    Opis:
    In a smart city environment, Intelligent Transportation System (ITS) enables the vehicle to generate and communicate messages for safety applications. There exists a challenge where the integrity of the message needs to be verified before passing it on to other vehicles. There should be a provision to motivate the honest vehicles who are reporting the true event messages. To achieve this, traffic regulations and event detections can be linked with blockchain technology. Any vehicle violating traffic rules will be issued with a penalty by executing the smart contract. In case any accident occurs, the vehicle nearby to the spot can immediately send the event message to Unmanned Aerial Vehicle (UAV). It will check for its credibility and proceed with rewards. The authenticity of the vehicle inside the smart city area is verified by registering itself with UAVs deployed near the city entrance. This is enabled to reduce the participation of unauthorized vehicles inside the city zone. The Secure Hash Algorithm (SHA256) and Elliptic Curve Digital Signature Algorithm (ECDSA-192) are used for communication. The result of computation time for certificate generation and vehicles involvement rate is presented.

    Opis:
    An Intelligent transportation system (ITS) focuses on application of smart vehicles. The vehicles are equipped with significant computing, communicating and sensing capabilities to provide services to travelers or the goal of providing safety massages in emergency situations. Vehicular network may also be used for Internet access, inter-passengers communications and entertainment. To understand the behavior of such networks as well as to provide good services to the travelers many issues have to be managed, some of them are: call handover between vehicles in vehicular network, speed Vs capacity, security of call, network topology, and network fragmentation. In this paper we study such vehicular networks and explain these issues and the related work. Detailed study of practical node mobility models based on mobility states and the quality of practical links based on received signal strengths are used as inputs for system capacity studies. Experiments were run in Sydney based on drive tests with mobile terminals deployed on them. Then some new ideas for managing the vehicular networks are proposed.
