Blockchain-Based Access Control Techniques for IoT Applications

The Internet of Things is gaining more importance in the present era technology. It considered as one most important technologies everyday life. Moreover, IoT systems are ceaselessly growing with and devices. They scalable, dynamic, distributed, hence origin crucial security requirements IoT. One challenging issues that community must handle recently how to ensure an access control approach manages such a system. Traditional not suitable for large-scale distributed network structure. Most them based on centralized approach, where use trusted third party (TTP) obligatory. Furthermore, emergence blockchain technology has allowed researchers come up solution these issues. This highly used record data. Additionally, it great potential managing requests. paper proposed blockchain-based taxonomy according nature: partially decentralized fully decentralized. presents overview solutions different applications. Finally, article analyzes works certain criteria authors deem important.
