As the cyber theft is increases, information safety and confidentiality are the major issues in wireless communications. 6G technology overcomes these difficulties to build a secured intelligent transportation system (ITS). Conventional transportation system faces high computation cost when road side unit (RSU) process each authentication vehicle request. In this chapter, to address this issue we introduced batch authentication and key exchange to secure user privacy and prevent attacks. To ensure message integrity, this system provides location-based information safely from RSU to vehicle without any changes. This system reduces the communication and computational costs. Simulation is performed using simulation of urban mobility (SUMO) simulator.
