|dectelization within IoT eliminate the need to use distributed networks within IoT to communicate only with servers that may face difficulties related to the internet, vulnerabilities, DDOS, or hijacked, merging blockchain with IoT converted IoT system into decnterlized with many benefits outcomes from this conversion.|
An encryption scheme homomorphic technique (HE) is a method that encrypts the cipher data without the need to decrypt it,paillier encryption method is used.
This paper aims to propose a system that integrates Paillier cryptosystem homomorphic technology with IoT and blockchain technology to provide decentralization to the IoT environment and improve security. The proposed system results in improving the IoT device’s work environment by solving the main challenges of security using blockchain, privacy using homomorphism, and data volume using blockchain, this system evaluated using standard terms using to evaluate the blockchain such as throughput, transaction per second, and Block latency time to ensure the effectiveness of the system.
