A Novel Data Security Model of D2D Communication Using Blockchain for Disaster

Multiple natural disasters cause the loss of billions of dollars, resources, and human lives. Integrated with the latest emerging technologies like Device to Device (D2D) communication and the Internet of Things (IoT) plays a significant role in the current disaster management system by extending coverage area, processing a massive volume of data, minimising the data traffic load, as well as energy-efficient communication. However, several critical security issues still exist, which have attracted many researchers’ attention. Blockchain is one of the latest technologies that could solve D2D and IoT devices’ different security issues. This paper analysed and discussed various security issues for early and post-disaster communication systems. It proposed a Hyper ledger Fabric (HLF) Blockchain-based communication model for the disaster communication system to overcome security threats and enhance the response system by providing authenticated and authorised the participant node. This paper implemented the HLF Blockchain framework to validate the proposed model and measure the system performance matrices.
