I-PRE: Improved Proxy Re-Encryption Scheme for VANET
Vehicular Ad hoc Network (VANET) is a network of self organized vehicles and road-side infrastructure communicating with each other over wireless, with a view to improve tra#64259;c safety and efficiency. Data interchanged over VANETs often play a vital role in traffic safety. Such information must be accurate and truthful, as lives could depend on this application. Thus, Authentication is one of the important services for traffic safety in VANET. In this paper, we discuss various approaches of authentication in VANET such as Digital Certificates (DCA), Pairing and Proxy Re-encryption (PRE). PRE is a better solution among all existing authentication approaches but still it is vulnerable to many attacks i.e. Denial of Service. We proposed an improvement in the PRE (I-PRE) that overcome the exiting attacks on PRE. The effectiveness of the proposed scheme is analysed using OMNet++ simulator.
