As an extension of cloud computing, fog computing environment as well as fog node plays an increasingly important role in internet of things (IoT). This technology provides IoT with more distributed and efficient applications and services. However, IoT nodes have so much variety and perform poorly, which leads to more security issues. For this situation, we initially design a security scheme for the IoT fog environment. Based on the combination of Blockchain and Trusted Execution Environment (TEE) technologies, the security of data storage and transmission from fog nodes to the cloud are ensured, thus ensuring the trustworthiness of the data source in the fog environment.
