LoRa Wireless network technology is a network communication technology that is widely used on the Internet of Things platform,providing long-distance connectivity facilities with ultra-low power consumption.Because AES-128 en-cryption is used for payload transport from the end device to the application server,it provides strong security features.Due to the design of its own network architecture,gateway is the weak point in the network,which provides an opportunity for attackers.This paper proposes a new certificate authentication technique to protect the gateway in the network.In this paper,the experimental simulation environment of LoRa wireless network technology is constructed for effective verification,which greatly improves the security of LoRa wireless network technology.
