RSA BASED SECRET KEY GENERATION AND AUTHORIZATION METHOD IN CLOUD BASED VANETS

Private transportation has become a daily need for most people nowadays. Because of the increased use of private transportation by modern society, road accidents have become a major issue. Vehicular communication is one of the methods to reduce the number of dangerous accidents. It is possible to communicate between two vehicles, Known as Vehicle to Vehicle Communication (V2V). Road Side Unit (RSU) is a communication with a specific fixed unit. If communication is established between the vehicle and nearby infrastructure (V2I), accidents can be avoided. Inter Vehicular communication is the term for this type of communication. It also lets vehicles share information such as post-accident investigation, safety information for accident prevention, traffic jams, and many more. Europe and North America are at the forefronts of research to conclude vehicular communication standards. It recognizes technical specification for enabling the communication between vehicles and the road infrastructure and between the various manufacturers. In the existing method, Cloud-based VANET helps to monitor the road condition. Through the connected Vehicular Ad-hoc Network (VANET) and cloud computing technologies, the entities in VANET were able to access the valuable storage and computing services made available by some cloud service provider. The benefits cannot be given away for free because their combination introduces various privacy and security requirements for VANET applications. The authority should monitor real-time road condition using a cloud server, so sound responses to emergencies can be made on time, according to the cloudbased Road Condition Monitoring (RCoM) scenario examined here. Vehicles on site should report information if any dangerous road condition is detected, such as geologic hazards or accidents. Three major issues are discussed in RCoM. An efficient RCoM method was suggested to address these three issues to analyze its efficiency theoretically and to demonstrate its practicality through experiments. They were generated using random numbers and help us in authorization process. So, the malicious vehicles easily identity it. To resolve the issues mentioned above, one Improved Road Condition monitoring system (IRCOM) was initiated. Using the random key generator, the first sub authority delegation is performed, and by using the RSA algorithm, the vehicle registration is attained by generating individual keys. The distribution of the token is based on the individual key and time stamp assigned to each vehicle. Cloud will categorize the received report using the key, token and time stamp. Finally, the route authority will decode the reports and, if necessary, will take the appropriate action.
