Classes of attacks in VANET

Last few years, vehicular network has been taken more attention of researchers and automotive industries due to life saving factor. Vehicular Ad hoc Network (VANET) needs security to implement the wireless environment and serves users with safety and non safety applications. Attackers generate different attacks in this life saving vehicular network. In this paper, we propose five different classes of attacks and every class is expected to provide better perspective for the VANET security. The main contribution of this paper is the proposed solution for classification and identification of different attacks in VANET.

Attacks on Security Goals (Confidentiality, Integrity, Availability) in VANET: A Survey

In recent years, the VANET has received a greater attention among researchers in academia and industry due to its potential safety application and nonsafety application. Malicious users are one of the types of attackers in VANET and create the security problems. Confidentiality, integrity and availability (CIA) are major components of security goals. The increasing research interest, potential applications, and security problem in VANET lead to the needs to review the attacks on security goals. In this paper, the aim is to present the survey of attacks on security goals and to describe in details the nature of attacks and the behaviour of attackers through different scenarios in the network. The paper also provides a better understanding of security goals and finally it provides an analysis and classifies the attacks on the basis of security goals into different threat levels that can help in the implementation of VANET in real life.

A novel vehicular SMS system (VSS) approach for Intelligent Transport System (ITS)

Road accidents and traffic jams are common problems being the target of a lot of research works to be resolved in current traffic system. Vehicular Ad hoc Network (VANET) is commonly part of Intelligent Transport System (ITS) which is directly involved in handling these problems and aims to make journey on road comfortable. In this paper, vehicular SMS system (VSS) is proposed based on cellular network to provide VANET services to users through SMS system. It has the potential of being more cost effective solution as compared to VANET but needs further research to resolve its trust and privacy issues.

New card based scheme to ensure security and trust in vehicular communications

Potential safety and non safety applications of vehicular network provide solutions to current traffic system. Dynamic topology of the vehicular communication network and high speed of the vehicles make it a challenging task of authenticating the users. Researchers have proposed different types of authentication mechanisms for secure vehicular communication. We propose a new and practical card-based scheme to make it possible for authentication of users and at the same time enable transactions with vehicle Service Provider (SP). Our proposed scheme provides secure communication environment while vehicle communicating with other vehicles (V2V) or communicating with road site unit (V2R). The SP is key module in vehicular business model in that it provides non safety services to vehicular users during their journey. Our proposed scheme will help solve the security and trust issues in authentication of the users while taking service from service providers.

Trust levels in peer-to-peer (P2P) vehicular network

Security is one of the most important issues in new life saving vehicular network, whereas trust is key component of security in vehicular applications. These applications serve users when components (user, vehicle and RSU) of the network behave in an expected manner in peer to peer vehicular communication. Whenever any component of the network unexpectedly changes their behavior then it would be harmful for other users of the network. In this paper, we are proposed three different trust levels in peer to peer vehicular network. Purpose of proposed trust levels to discuss in detail is the functionality of different component of network which circumvents the attacker and emphasizes the role of trusted users in peer to peer vehicular communication.

Towards Improving Security in VANET: Some New Possible Attacks and Their Possible Solutions

Vehicular ad hoc network (VANET) is taken more attention from the end user due to its potential safety and non-safety applications. The basic design objective of these applications to serve the users and provide safety of human lives during their journey. The role of the end user is more prominent for next generation vehicular networks. An attacker is one of type of end user, but their role in the network is negative and creates problems for other components of network. So in this paper, we will discuss two new types of attacks which are called road side traffic signal attack and also Internet attack in vehicular network. The authors will explain an attackers behaviour and how he/she will launch an attack on a road side traffic signal and Internet services and create problems for other users of network. Through different scenarios, it will explain the effect of these attacks on other components of network. Trusted Platform module (TPM) is a security hardware module and it is provided the secure communication in network, so we will discuss in detail how this security module will handle these newly address attacks in network.

Using Trusted Platform Module (TPM) to Secure Business

Safety of human life during journey is one of most important objective of intelligent transportation system (ITS). Potential safety and non -safety applications of vehicular ad hoc network (VANET) also provides safety of human lives and also comfort passengers during their journey. Comfort applications are also provided entertainment services to users and make journey more enjoyable. Comfort applications provide opportunities for business parties to setup their business near the highway. So in this paper, we are presenting the secure business communication (SBC) model and explain the components of proposed model. TPM is a security hardware module and it is used inside the smart vehicle. TPM is a core component of proposed SBC model and it will ensure secure communication between user and business parties in VANET. The core objective of secure business communication (SBC) in VANET is to serve the end users through potential applications of VANET.

Using TPM to ensure security, trust and privacy (STP) in VANET

Safety and non-safety applications of VANET provides solutions for road accidents in current traffic system. Security is one of the key research area for successful implementation of safety and non-safety applications of VANET in real environment. Trust and Privacy are two major components of security and dynamic topology and high mobility of vehicles make it more challenging task for end users in network. We propose a new and practical card-based scheme to ensure the Security, Trust and Privacy (STP) in vehicular network. Proposed scheme is based on security hardware module i-e trusted platform module (TPM). The basic objective of proposed scheme is to create trusted security environment for end users in network and user take benefits of potential application of VANET.
