【Abstract】With the advent of the Internet of Things (IoT), smart devices have now changed their dimensions to provide applications in different domains such as medical, agriculture, and Industry 4.0. Although IoT provides more diversified applications, enhancing the security in IoT remains on the darker side of the research. Traditional IoT systems involve a third party to secure sensitive data during transmission in an IoT environment which can lead to complex and serious problems. To overcome security issues and eradicate third-party involvement, Blockchain technology is the modern-day solution in an IoT environment. In the context of a Secured IoT system, we proposed a novel chaotic encryption-based blockchain-IoT architecture to clinch the security and privacy of data. Since smart sensors and image sensors are used widely in an IoT environment, the proposed scheme was tested with different image sets to evaluate performance metrics such as Number of Pixel Change Rate (NPCR), Unified Averaged Changed Intensity (UACI), Correlation Coefficients, and entropy under different attack scenarios. We obtained an NPCR of 99.65%, a UACI of 34%, and an entropy value close to 8. These values incite that the novel chaotic encryption-based blockchain-IoT architecture will be safe from IoT attacks. Results showed that integrating chaotic encrypted blockchain architecture with IoT could be more effective in defending attacks.
