A blockchain - based access control solution for IoT

This paper proposes a security framework for Internet of Things (IoT) based on blockchain. The solution provides the two features: (1) Access control for IoT devices, which allows users to pay a fee to the device’s owner to access the device for a certain period of time. | Huynh Thanh Tam Nguyen Dinh Thuc Tan Hanh A BLOCKCHAIN-BASED ACCESS CONTROL SOLUTION FOR IoT Huynh Thanh Tam Nguyen Dinh Thuc Tan Hanh Posts and Telecommunications Institute of Technology HCM Vietnam University of Science VNU-HCMC Vietnam Abstract This paper proposes a security framework for In this paper we propose a decentralized security Internet of Things IoT based on blockchain. The solution framework for IoT in which owners can manage and allow provides the two features 1 Access control for IoT devices users to connect their devices in a period of time depending which allows users to pay a fee to the device s owner to access on the amount of payment. Moreover because of the the device for a certain period of time. When the access time expires the connection will automatically be denied by a limited storage space in the owners servers they may proxy of the owner And 2 Decentralized storage service conduct a payment to store long term in the peer-to-peer providing storage space for IoT data. Device owners have to storage system the total amount of payment depends on pay for the system to rent storage space. The total amount of the size of the data and storage time. Particularly payment depends on the size of the data and storage time. considering in the context of a smart home area where has The stored data on the storage system are automatically some public areas such as kindergarten sport areas discarded when the storage time has expired. We also present a mechanism for privacy-preserving data sharing on peer-to- parking park. In the kindergarten the owner has camera peer networks between owners and the storage system. We devices to monitor children. Parents can access the camera use blockchain technology to manage IoT devices access to view their children s activities by submitting a information and data storage information. The Proof of transaction to the owner. The deadline is fixed when the Authentication consensus is used to provide a lightweight .
