Abstract

Life has become more convenient, efficient, and productive in aspects like homes, healthcare, and other businesses’ due to applied IoT. Nonetheless, the proliferation of IoT has led to enormous data production, which has presented daunting tasks of providing sound protective security solutions. It is crucial to address the above challenges in order to protect the data assets in IoT systems. This work deals with the concern on how to extend Hyperledger Fabric to IoT, this being a very crucial aspect in allowing for secure techniques in the collection, storage and sharing of data. Hyperledger Fabric offers advanced capabilities of smart contract and offers authorized and conditional access control, and this feature alone is enough to fulfil the IoT security needs. Therefore, this paper introduces a new solution related to the existing security problems in permissioned blockchain architecture, which is based on a four-tier architecture integrated into the Hyperledger Fabric platform. As for architecture, our proposal divides it into four layers: the application layer, the blockchain platform layer, the cloud storage layer and the IoT device layer, to tackle the problems of security and efficiency of the whole process. To establish the proposed solution, a data literature review has been carried out to collate the analysis and apply the data from the different studies. This paper shows that the deployment of blockchain technology in IoT environments also optimises IoT systems in terms of security, efficiency, and capacity in terms of IoT applications. As more and more IoT solutions appear and evolve, the usage of block chain technology as a whole and the specific Hyperledger Fabric platform in particular opens the way to overcoming the rather fluid issues of this constantly developing sphere.
