Conventional and Hybrid Encryption Schemes for Security against Attacks in Vehicular Adhoc Network

Vehicular Adhoc Network (VANET) is an important technology in Intelligent Transportation System (ITS) that furnishes the communication between conveyances and the Road-Side Units (RSU) within the vehicular network. In VANET, protecting the data from several distinct security threats in an untrusted environment is still a contentious issue. These security attacks have higher possibility in disrupting the normal operations within the vehicular network and the communication between the conveyances get compromised by injecting the false data and are vulnerable to various distinct attacks into the network. This paper discusses the security issues and several distinct conventional encryption algorithms that support in preventing the various attacks during the transmission of data in the vehicular network. This paper also compares the traditional encryption mechanisms with the hybrid encryption scheme in terms of security and performance.
