Abstract

The entire Internet of Things (IoT) industry is anticipating advancements in network architecture and the creation of novel security methods that will make it possible to control and access Internet of Things (IoT) devices in a flexible, reliable and secure manner. Smart devices are susceptible to assaults due to low processing power and storage capacity because current security or cryptography techniques are ineffective. Blockchain technology is used in this project along with Internet of Things (IoT) for security authentication and verification purposes.
Blockchain's decentralization, anonymity, and proof-of-security features can stop centralized servers from colluding and collapsing in a single spot due to single point failure. In this project, a novel Multi-Input Data Concatenation (MIDC) technique is implemented to concatenate the multiple inputs for optimizing the blockchain storage. Here, the blockchain network checks for authenticity when a user requests access and then approves the request based on the data that has been stored. The integration of Blockchain into the Internet of Things (IoT) system can be able to remove the barriers preventing the advancement of Internet of Things (IoT) design and security. The proposed work outperforms existing cutting-edge methods by offering enhanced security performance, decreased Central Processing Unit (CPU) utilization time and power consumption, decreased cost, and decreased memory usage.

Keywords: Advanced Encryption System, Blockchain, Encrypted Data, Multi-Input Data Concatenation, Security authentication.
