The data of Internet of Things(IoT) perception layer is diversified and heterogeneous, which leads to a large security risk in IoT perception layer and can cause great loss once it is attacked by network hackers. Trusted computing technology is applied to the security design of the IoT perception layer to improve the security of the IoT system. Meanwhile, the trusted connection of IoT perception layer is analyzed and the trusted chip is designed based on the composition of IoT and trusted computing. The trusted chip is applied to identity authentication and data transmission, which effectively protects the identity information and sensor data information of IoT perception layer nodes and secures the IoT perception layer nodes and servers. This research has a reference value for better using trusted computing to ensure the security of IoT perception layer.
