A Novel approach for Implementing Security over Vehicular Ad hoc network using Signcryption through Network Grid

Abstract

Abstract-Security over Vehicular ad hoc network and identifying accurate vehicle location has always been a major challenge over VANET. Even though GPS system can be used to identify the location of the vehicle they too suffer from major drawbacks. A novel approach has been suggested by the author wherein the VANET is made more secured by using Signcryption technique and at the same time unique approach of using Network Grid to flawlessly identify the location of the vehicle has been proposed. VANET as compared to Mobile ad hoc network or MANET is highly dynamic and unsecured. Providing security and at the same time preventing the current transmission to attain loss due to frequent path breakage over VANET has always been a major challenge. Moreover, the computation cost required over VANET should be less as compared to MANET. So, even if a security protocol is to be implemented over VANET care must be taken so that the computation cost doesn"t increase. A unique public key cryptography technique Signcryption as proposed by Zengh [1] has been suggested in this paper. Signcryption is a cryptography technique which combines the two step of Digital signature and Encryption in one step and hence reduces the computation time up to great extent as compared to Signature-then-Encryption.
