Comprehensive view of security practices in vehicular networks

With expectation of widespread adoption of Connected Vehicles Technology (CVT), security within the vehicular networks has come under scrutiny. Owing to the nature of CVT applications, security flaws can result not only in loss of data or network function but also in fatal accidents. Security mechanisms that can account for privacy, authentication, integrity, and non-repudiation while having an acceptable communication overhead are imperative to the functioning of CVT applications. While this field of study is rapidly evolving with a wide range of studies and security solutions being proposed for different areas of CVT security, literature documenting the comprehensive picture of current security protocols and practices is missing. This paper attempts to remedy this by documenting recent advances in CVT security with the goal of providing an efficient jumping off point for future research in CVT security development.
