Abstract: The development of the Internet of things (IoT) has led to the emergence of a large number of smart home devices on the market, which greatly improved the quality of our lives. As the key entry device in smart home and the first line of defense for home security, smart door locks have become the focus of security researchers. Smart door locks are essentially fixed devices that require authentication credentials to be opened, and integrate multiple digital authentication technologies. They are also an excellent object to study the security of identity authentication for IoT devices. In this paper, smart door lock is taken as an example to analyze the security of identity authentication through attack experiments. According to the analysis results, several security risks faced by identity authentication are summarized, and security recommendations are given for these security risks.
