Vehicle authentication and message hiding protocol for vehicle to vehicle communication

Along with the advancement in wireless communication and vehicle technology, while traveling, exchange of information, has become the most promising research field. Security is central to every major challenge, the mobility model faces nowadays. Proving the identity of one vehicle driver to another during communication, along with message sharing is the main issue to cope with. The main goal of this research is to achieve not only the confidentiality of the message, but also the authentication of vehicle drivers. In this paper, an efficient approach is adopted mainly focuses on the authentication of the vehicle drivers. In this paper vehicle to vehicle protocol is proposed. Steganography BED (Bit-level Extend and Dwindle) technique is used for hiding the message image of variable size behind the cover image. Mapping of Text Message bits with Cover Image decimal values is done, character by character, to generate the new image decimal values and is termed as Even-Odd toggle (E-O Toggle) approach. For authentication and confidentiality purpose, Elliptic Curve Cryptography (ECC) is applied to the user message image, before the embedding with the cover image.
