Trusted Internet of Things Based on Trusted Computing

Thanks to the rapid development of mobile Internet, the application and popularity of the IoT are becoming wider and wider. However, new security threats and attacks are constantly emerging, IoT has the characteristics of massive terminal devices, diversification and intelligence of devices. Therefore, it becomes a hot research direction to ensure the security and trustworthiness of the IoT computing environment today. Trusted IoT applies trusted computing technology to IoT scenarios to ensure trustworthiness. The software and hardware resources are limited in IoT scenario, such that low power consumption and availability are required. Therefore, the design and implementation of a trusted IoT will confront many security challenges. This paper summarizes the research ideas and states of the trusted IoT from three aspects: the lightweight root of trust system, software attestation, and secure code update, and introduces representative research results for trusted IoT.
