With the rapid development of the Internet of Things (IoT), a vast number of devices are now connected to networks. While edge computing has enhanced data processing efficiency, it also introduces new security challenges. Traditional security architectures can no longer meet the complex requirements of IoT devices, and the zero trust security concept, which emphasizes 'never trust, always verify,' offers a new direction. This paper focuses on issues such as identity forgery, data leakage, and network attacks in IoT devices under edge computing. By constructing a zero trust security architecture that includes identity authentication, access control, data encryption, and security monitoring, this paper aims to enhance device security and stability and reduce security risks.
