BDESF-ITS: Blockchain-Based Secure Data Exchange and Storage Framework for Intelligent Transportation System

The communication in Intelligent Transportation Systems (ITS) suffers from various security and privacy related issues as several attacks, like replay, man-in-the-middle (MiTM), impersonation, data leakage and unauthorised data update attacks can be mounted by an adversary. Therefore, we need a robust security mechanism to sort out such issues, which can be further enhanced through the use of mechanism of blockchain technology. In this paper, we propose a blockchain-based secure data exchange and storage framework for the ITS (in short, we call it as BDESF-ITS). We conduct the security analysis of the BDESF-ITS to prove its robustness against various possible attacks. The practical implementation of the BDESF-ITS is also carried out to observe its behaviour with the real world settings.
