Enhance the Security by using Hashing Technique and Trust Values in Vehicular Ad Hoc Networks
Vehicular Ad hoc Network (VANET) is the favorable method to enhance the safety of divers and passengers. It becomes a basic element of the Intelligent Transportation System (ITS). It has created by applying the concepts of Mobile Ad Hoc Networks (MANETs) – which is an application of a wireless network for exchanging the data – to the domain of vehicles. They become a main element of intelligent transportation systems. In existing technique drawback is the Authentication Server (AS) gives all the working to Law Executor (LE) means AS send information to RSU, RSU send this information to law executor and then login process start but if LE behave maliciously then this authentication process fail. In our propose work, we calculate the trust of each vehicle's on the basis of their behavior. Each vehicle calculates the trust of its neighbor and send this value to AS by RSU then AS update these values and then broadcast this value by RSU, now all the vehicles have a trust value of its neighboring vehicles so that send the data by using hashing technique and use trusted path to send data source to a destination so that security enhances.

Overview of Trust Management in VANET and Various Cryptography Fundamentals
International Journal of Future Generation Communication and Networking, 2016
Vehicular Ad Hoc Network (VANET) is a more influential network in which vehicles depend on each other to communicate and for the secure exchange of the messages. With the improvement in the technology, mainly the vehicles are equipped with Wi-Fi and GPS devices to improve the traffic handling and road safety. But many vehicles may broadcast the bogus messages for their own purpose, so it needs a trustful environment and an effective trust management schemes to prevent the network from the various malicious attacks. Trust establishment is very challenging as the network is highly mobile and vehicles may come in or depart at any time. In this paper, we first discuss the VANET model to describe the environment, and then the trust management schemes to secure the network and lastly the various cryptography fundamentals for the fast and safe message transfer.
Trusted computing in vehicular ad hoc network (VANET
Trust is the key part of the security and challenges task in future life safety vehicular communication. Vehicular communication is based on peer to peer communication and each peer has embedded sensor s inside and performs all computational tasks as well as security functions. The trusted Platform module (TPM) is used inside the vehicle and plays a key role to establish trust within the vehicle and also with other vehicles and network infrastructure. In this paper, a protocol is proposed which is based on a property based attestation (PBA) also known as Vehicular Property based attestation Protocol (VPP). In this proposed protocol, it is not based on the properties of the hardware and software of the vehicle; rather it depends on the static or dynamic properties of the system which has been pre configured. We would expect that the protocol will fulfil the need for a more secure and trusted mechanism for users using the safety and non-safety applications and services in the vehicular network.
Vehicular Ad Hoc Networks: An Approach to Provide Secure and Trusted Data
2012
A Vehicular Ad-Hoc Network (VANET) facilitates communication between vehicles and infrastructure. The aim of VANETs is to enable moving vehicles by providing safety and non safety messages. Due to the characteristics of VANET, the existing relative positioning techniques developed initially for Ad hoc or sensors networks are not directly applicable to vehicular networks. Vehicle-to-vehicle communications is used to collect data from neighborhood vehicle with the help of sub-VANET. In this paper we assess how can data providers earn their person's trust and provide the security, when a third party is processing sensitive data in a remote machine located in various location in the cities? A concept of utility of vehicle's data has been represented to provide the various services to the peers. Emerging technologies can help address the challenges of Security and Trust in data computing.
Forming vehicular web of trust in VANET
… (SIECPC), 2011
Today's VANET applications are vastly focused towards fulfilling users' requirements on road and making their journey safe and comfortable. In particular, safety applications will provide secure information to users and introduce mechanisms to help reduce the death rate due to road accidents. The most important aspect in such environment is the integrity of this safety information; it must be at all times prevented from being altered by attackers. Attackers try to get benefits from the nature of open wireless medium to launch different kind of attacks in the network to achieve their specific goals. Current DSRC is used as a communication medium for sending the safety and non safety messages from vehicle to vehicle (V2V) and vehicle to infrastructure (V2I). With the introduction of trusted computing several years ago, Trusted Platform Module (TPM) is a security hardware that can potentially handle the software attacks on VANET and maintain the integrity of the data within vehicular network. The main idea behind trusted computing is the hardware based TPM which contains active security modules that supports chain of trust to be built within components of the network. We propose a new model for chain of trust within vehicular to handle all types of attacks and maintain the integrity of messages. Direct Anonymous Attestation (DAA) digital group signature scheme play a key role for developing web of trust and provides security and privacy for vehicle.

A trust infrastructure based authentication method for clustered vehicular ad hoc networks
Peer-to-peer Networking and Applications, 2020
Vehicular Ad hoc Networks (VANETs) as a subset of mobile ad hoc networks which allow communication between any vehicle with other adjacent vehicles, road side units and infrastructure. In these networks, the purpose is to enhance the security, improve the management of urban and road traffic and provide services to the passenger. Due to problems such as reliability and privacy, messages that are exchanged in the network should be confidential and secure. Therefore, we need a secure topology to maintain trust, which enables the cryptographic process. In this paper, a trust based authentication method for clustered vehicular ad hoc networks is proposed. The efficient authentication method should be able to accurately detect malicious nodes and reduced delay and overhead. The main purpose of the proposed method is to create trustworthy and stable clusters that lead to the stability of the entire network. For this purpose, we estimate the trust degree of each vehicle by combining the trust between vehicles and the trust between the vehicle and Road Side Units (RSUs), and Cluster Heads (CHs) are selected based on this estimated trust degree. Cluster Heads along with verifiers are responsible for monitoring each vehicle. On the other hand, the cluster heads provide an optimal and secure route for transmitting messages. Messages are digitally signed by the sender and encrypted using a public/ private key as distributed by a Trusted Authority (TA) and decrypted by the destination; so that each message contains a certificate from a trusted authority. In this identification, the sender and receiver of the message are verified and authentication will be achieved. By simulation results, it is proves that the proposed method increases the accuracy in detecting malicious nodes and the packet delivery ratio, and decreases the delay of authentication and overhead.
