摘要：This article introduces the security risks of the commonly used MQTT protocol in the Internet of Things and the security risks caused by smart door lock vulnerabilities, aiming to solve the problem of public MQTT agent leaking smart lock data, causing attackers to use the sensitive data to physically locate and remotely control the connection to the smart door lock supplier Any lock issues in the cloud infrastructure. This paper presents a wireless sensor network authentication encryption method based on SM9 algorithm. By implementing and deploying sensor network authentication encryption in practical applications, it avoids the leakage of sensitive information from public data exposed on the Internet.
