Significant developments have taken place over the past few years in the area of vehicular communication systems in the ITS environment. It is vital that, in these environments, security is considered in design and implementation since compromised vulnerabilities in one vehicle can be propagated to other vehicles, especially given that V2X communication is through an ad-hoc type network. Recently, many standardisation organisations have been working on creating international standards related to vehicular communication security and the so-called Internet of Vehicles (IoV). This paper presents a discussion of current V2X communications cyber security issues and standardisation approaches being considered by standardisation bodies such as the ISO, the ITU, the IEEE, and the ETSI.

Communications between vehicles are seen as a solution for road transport problems, such as accidents, inefficiencies, traffic congestions, fuel consumption, and exhaust emissions. However, before implementing such a solution, some preliminary analysis is needed. First, the most convenient communications technologies should be selected for each application and specific communications architecture should be deployed to support such services. Standardization is essential for successful deployment.[...]

“…A key limitation of the priority based schemes is their dependence on transmitter-receiver distance which could not be calculated before the packet is authenticated. Indeed, since these location information are exploited prior to their verification (using ECDSA), existing approaches can be vulnerable to various security threats, including broadcast tampering and denial of service (5), impacting thus the safety of the end-to-end ITS application.…”

“…This is especially true in high density VANETs scenarios, where each vehicle might receive several hundred (or thousand) BSMs per second from neighboring vehicles, and which could not all be verified due to the limited computational resources. As a result, several important BSMs from close by neighbors get dropped due to timeout, resulting in loss of awareness for safety applications (5). A number of techniques have been proposed in the literature to optimize verification processing time of BSMs (10; 11; 12; 13; 14; 15; 16), and thus to improve the vehicle situational awareness.…”

“…BSMs allow vehicles to extend their vision beyond line of sight and develop a local dynamic map (LDM) (4) containing a clear picture of surrounding traffic. LDM is a database that collects information from various sensors, road side units and neighborhood vehicles to facilitate various ITS applications (5), such as intersection collision warning, wrong way driving warning, approaching emergency vehicle warning application, etc.…”

Vehicular ad hoc network provides safety applications for next generation intelligent transport systems. By periodically transmitting mobility information in basic safety messages (BSMs), vehicles get an overview of the neighborhood. As applications involving vehicular networks impact human safety, reliability of BSMs is a key requirement, which however is a challenging task in heavy traffic scenarios where many BSMs are queued up simultaneously for signature verification. This results in long verification delays for many critical BSMs from nearby vehicles. To overcome this challenge, we propose two adaptive security mechanisms in this paper that can be used by the ITS applications to enhance their QoS and maintain good level of security. The first technique is a receiver-oriented technique that uses channel aware mechanism to prioritize the signature verification of BSMs from closer neighbors. The second technique is transmitter based that can adaptively select the best security level for BSMs according to cryptographic loss rate. Simulation results verify the performance enhancement achieved by the proposed framework in terms of several safety awareness metrics as compared with the existing schemes. This paper is a revised and expanded version of a paper entitled
