Abstract
The Internet of Things (IoT) is an important area of next-generation information technology, and its value and significance are widely recognized. While providing development opportunities, the IoT also presents major challenges. Security and privacy have become severe issues that cannot be ignored in the development of the IoT in this paper, so we will propose an IoT information security protection scheme based on blockchain technology. The scheme utilizes the security features of the blockchain combined with the AES encryption algorithm to encrypt the original IoT information, and the ciphertext distributed storage can effectively solve the IoT data storage problem. Experiments shown in this scheme could reduce the operation and credit cost of centralized network. At the same time, the blockchain-based IoT information security protection scheme combined with cryptography knowledge can effectively solved the big data management and trust faced in the development of the IoT, security and privacy issues.
