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

Abstract

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.

On a simulation study of cyber attacks on vehicle-to-infrastructure communication (V2I) in Intelligent Transportation System (ITS)

“…Consequently, Raya et al [6] proposed the use of many transceivers at varying frequency bands as a feasible complement [6]. According to Sumra et al [3], attacks (e.g., DoS attacks) that severely impact the network functions -availability attacks -are more consequential/have more priority over other attacks on the remaining security goals of integrity, and confidentiality [3].…”

“…As a privacy-preserving approach, Raya et al [6] proposed the use of dynamic, anonymous, and preloaded keys that change according to a vehicles travel speed. Authorized personnel -after a judicial approval from a judge -can, however, circumvent a vehicle drivers anonymity by reconstructing key information using the uniquely identifiable electronic license plate (ELP) in order to prove liability [ [24], broadcast tampering attack [3], malware attack [3], spamming attack [3], blackhole attack [3], and Sybil attacks [7]. Attacks against availability -jamming attack in the physical layer for example -can be mitigated by periodically switching the communication channel, and/or the communication technology used [5].…”

“…Although the use of pseudonyms enhances privacy, a complementary privacy preserving measure is to only reveal enough information to other nodes as absolutely necessary to prevent tracking, and/or inference linking [2][7].Attacks on availability manifests in the form of DoS: high frequency signals can be used to jam the communication channel in order to overwhelm it or deplete other network resources[3] [21][22] [23][24], including DDoS[3] …”

SEMD: Secure and efficient message dissemination with policy enforcement in VANET

“…(1) Data confidentiality: Confidentiality is one of the major security requirements in VANET [30]. The vehicles which do not have security keys satisfying the access policy of the messages must be prevented from accessing in VANET.…”

A method for defensing against multi-source Sybil attacks in VANET

“…1. Different from the Delay-tolerant networks [2][3][4], the characteristics of fast and dynamic topology, autonomous movement and the influence of traffic rules, road and weather conditions bring many security threats to VANET [5,6]. To deal with these threats, many applications of VANET give each vehicle a unique identity, and take some security rules and methods with these identities.…”
