Cryptography and blockchain technology are super important for keeping all our smart devices safe in the Internet of Things (IoT) which can be considered as social security. As more and more of our gadgets connect to the internet, we really need to make sure they’re secure. This article talks about how we can use blockchain technology with IoT devices. Introduction and literature survey provides the challenges of having cryptography and blockchain technology in relation to Internet of Things, the proposed methodology provides the limited internet speed, and how blockchain affects how fast our devices can work and compare the cryptography attributes and blockchain technologies with the IoT world. To maintain the data safe and securely and provide the integrity and provide the high throughput, the Weight Allocation Authority (WAA) gives priority to users based on their characteristics. The Secure Hash Algorithm-512 helps make bigger data smaller. This work deals with the Hybrid Weighted Algorithm (HWA) and how IoT devices can improve the faster data transmission securely. WAA and HWA algorithms canalso create a safe and decentralized system that can quickly stop any bad transactions.
