Improving the detection of intrusion in vehicular ad-hoc networks with modified identity-based cryptosystem

Received Nov 10,2021 Revised Mar 21, 2023 Accepted Apr 30, 2023 Keywords: Identity-based cryptosystem Intrusion On-board unit Road side unit VANET ABSTRACT Vehicular ad-hoc networks (VANETs) are wireless-equipped vehicles that form networks along the road. In communicating with vehicles beyond the wireless range; intermediate vehicles or RSUs forward messages to the intended destination over multiple hops. [...]many initiatives in academic and standardization societies have been inspired by this new model of communication [5]. OVERVIEW OF VEHICULAR AD-HOC NETWORKS (VANETS) AND IDENTITY-BASED CRYPTOSYSTEM Improving the detection of intruders in VANETs with a MIBC forms the basis for this study. [...]the need to discuss the technology of VANETs and the fundamental of an identity-based cryptosystem cannot be sidelined. Development of vehicle authentication system The TA selects randomly a live session code SLc £ Z* and then generates vehicle membership authentication code to the vehicle using (5), and the control authentication key for the NCU using (6) respectively.
