Nowadays, smart cities are playing a significant role in high society, and each smart device is working in smart cities. The effort aims to store and maintain data securely by using AES and blockchain technology. The blockchain technology used to protect the IoT data hosted within the cloud. The block contains the data and timestamp. It allows peoples to access IoT data more securely from anywhere. We recommend a user verificationmethodemploying AES blockchainenablers in which enableredge to Ethereum smart contracts to validate users to retrieve IoT devices. Blockchain is essentially a distributed, shared, and entire database ledger that stores registry of resources and connections across the networks. It keeps data from attackers. The data is encrypted before outsourcing to the cloud and whenever required, decrypted by the cloud service provider.
