Nesnelerin interneti cihazları için blokzinciri tabanlı yetkilendirme modeli

The Internet of things has many unexplored potentials. Features such as low purchasing costs, low energy consumption, and small size make the internet of things indispensable and irreplaceable. However, the fact that they only have enough processor power to run particular tasks has led to the failure of implementation of many traditional security measures to the IoT environment, which are developed to date. Moreover, the lack of knowledge of developers about the security measures needs to be taken, creates lots of security loopholes and causes unauthorized persons to seize a lot of valuable information which undermines the trust of the users. Likewise, the unpredictable and rapid growth of IoT devices highlighted the importance of scalability, authorization, and encryption issues. Although partial solutions are being suggested to address these concerns, a generally accepted solution still doesn't exist. Thanks to its tamper-resistant, decentralized, distributed, programmable structure, Blockchain-based authentication, and access control systems can be used to strengthen IoT security. In this study, an application that provides authorization control and communication confidentiality without a reliable third party over the Blockchain network on restricted devices is presented. Furthermore, the security analysis that can be provided with this application is discussed by exemplifying specific attacks and performance data related to the limited device used are presented.
