Intelligent Transport System is considered as incipient technology in today’s environment. Active vehicles play an important role between IOT devices and ITS servers during communication. For the implementation and smooth functioning of ITS environment, numbers of ITS devices regularly communicate with ITS servers. Lots of data needs to be sent and received between ITS devices and ITS servers. During this journey challenges are also striking and increase the problems with real-time interaction, latency, security, quality of services, and delay across the journey of data.The main motive behind this paper is to work on mutual validation and key spreading using MNSOR (Modified Needham Schroeder and Otway Ress) Protocol in Intelligent Transport System environment to ensure timely interaction excluding clock synchronization, MITM attack protection of key given by ITS registration authority which moves from ITS Servers to ITS vehicle.
