VANET is very useful for solving traffic related problems and provide safety to life's of Drivers and passengers moving on the road, In this paper the proposed algorithm is helpful in authenticating a user and Solving Traffic related problems and provide more efficient broadcast system by covering Large distance. According to this Approach Vehicles can communicate with RSU,but there is no Vehicle to vehicle Communication. RSU can communicate with each other and update their information to the nearest RSU (NRSU), after that the emergency broadcast is also done by the NRSU. For security reasons we consider Vehicle numbers as their pseudonym and apply a new approach to authenticate the user, So that no unauthorized user can broadcast and send any false information to RSU. The public Key Cryptography is used to encrypt the communication between Vehicles and RSU.
As the development of processing power and communication speed increasing the possibilities of many thing which where thought impossible things are possible like communication between vehicles often referred as VANET-Vehicular networking. The possibilities of intruders even like even they can bypass through normal firewalls in industries now we have a problem in our VANET as the rate of speed increases with increase in processing speed it gives a good way to manipulate and get away details very fast. So we want ensure the robustness of our system, starting from the dashboard to the server. I had used the guidelines for modelling a application that will be used in dashboard in way that it will not provide any access to unauthorised data. I had used many technologies from traditional to implemented modified method to get accurate results with less nodes and less bandwidth. As we are working on a real time network here speed of decision making should be high with accuracy. We are going to discuss about practical system setup.
As the development of computer usage increases the need for security also increases as it had changed from entertainment based to high confidential files maintaining medium. So, there was a great improvement in the field of cryptography for data transfer and these are basically text and so they are more simple to process when compared to higher level of files like image and vide. This lead to the need for encryption methods for fast and secure techniques to avoid quality and quantity of high speed encrypted data files.. There are lots of highly secure cryptographic methods but they need to be compatible with image for processing. So the project goes along with a technic called hyper chaotic encryption technique with DNA sequence for hybrid image cryptography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
