Abstract
Internet-of-Things (IoT) began to be widely used in smart city, smart agriculture, and smart factories. However, security issues have always threatened the development of the IoT. Blockchain is the current promising technologies, which uses several security mechanisms to protect system. In this paper, we propose a security architecture for IoT based on blockchain. Sensor data in IoT are collected by border-router, and is sent to blockchain network. The communication of IoT system is encrypted by AES algorithm. Smart contracts are used to build the access control mechanisms. Finally, theoretical analysis shows that the proposed architecture can secure against different attacks, as well as low latency.
