A Hybrid Method for Secure Communication and Performance Analysis in VANET

Vehicular Ad-hoc network a subclass of Mobile Ad-hoc network with various features providing Vehicle-to-Vehicle communication, Vehicle-to-RSU communication, Vehicle-to-Trusted Authority Communication. VANET is gaining higher attention now days both in industry and academic area and has become a trending research topic for research but still a lot of improvements is required in this area. Security of data is one of the major challenge in VANET. Encryption of data with the help of various encryption algorithms came up as solution for securing communication in VANET. But existing encryption algorithms used to secure VANET’s are complex due to which data are not delivered on time and face a lot of problems like privacy of data ,non-repudiation and cost (i.e. communication cost, computational cost).In our proposed scheme we use a hybrid approach, which contain ECC algorithm( asymmetric algorithm).ECC algorithm is used for encryption of personal details (i.e. Speed, location, device address) and AES algorithm (symmetric algorithm ) is used for encryption for safety messages along with output of ECC algorithm. The objective of this hybrid approach is to perform double encryption on personal details for more privacy of personal data (using ECC and AES algorithm) and single encryption on safety messages (using AES algorithm) so safety messages are delivered on time and without any delay.
