HyperIoT: Securing Transactions in IoT through Private Permissioned Blockchain
M A Nithin, S Shraddha, Nishita Vaddem, V Sarasvathi · 2020
The Internet of Things (IoT) is growing at a lightning pace every year. There are more connected devices on the internet than people in the world today. However, the security and privacy of these networks are a primary concern for IoT applications which still faces some enormous challenges. The rise in the number of connected devices has led to more access points in the network making the systems vulnerable to cyber-attacks. Most customers are also typically uninformed of how much data is collected and how the data is used by the service providers. We propose HyperIoT as a decentralized, distributed, private blockchain network on the current IoT architecture to address these issues. The proposed architecture is based on Hyperledger Fabric framework. The model uses the concept of Fabric organizations and channels to create private sub-network per confidential domain where only permitted peers may subscribe to, thus restricting access to data. In addition to this, the proposed model has other security features such as permissioned membership, digital identity, and access control policies. The architecture proposed makes IoT data and transactions more secure, restricted, and transparent over a traditional IoT network.
