A hybrid security framework for the vehicular communications in VANET

Vehicular ad-hoc Networks (VANETs) are predominantly gaining higher attention in the recent times both in the academic and industrial field. The vehicular communications that intend to take place in the wireless medium support several safety applications of the vehicle passengers. The open communication environment of VANET enables the vehicle drivers to access the ubiquitous services which have become one of the main reasons for the increase of security vulnerabilities on vehicular communications. As a result, this paper emphasises the need of securing vehicular communications in VANET and proposes a hybrid security framework. The novel approach of this framework lies in combining RSA and AES algorithms to form hybrid cryptography and this hybrid cryptography is used to secure the vehicular communications in VANET. The simulation results have validated the performance and the security levels of this hybrid cryptographic method when applied to VANET.
