IoT gateway device capable of securely authenticating physical perception devices and access method thereof

Abstract

The invention discloses an Internet of Things gateway device capable of securely authenticating a physical perception device and an access method thereof. The device comprises: a device fingerprint extraction module, which can extract device fingerprint information of the connected physical perception device; a fingerprint processing module, which can extract the device fingerprint information of the connected physical perception device; The device fingerprint information extracted by the device fingerprint extraction module is processed into a fingerprint field with a fixed number of digits corresponding to the connected physical sensing device; the identification generation module can use the fingerprint field corresponding to the connected physical sensing device as the physical sensing device. Generate a unique device identifier containing a fingerprint field; the authentication module is respectively connected with the identification generation module, the physical perception device and the cloud server, and uses the unique device identifier containing the fingerprint field generated by the identification generation module to interact with the cloud server to access the Physically aware devices perform two-way authentication. It can use the unique device identifier constructed by the device fingerprint of the physical sensing device to realize two-way authentication and improve the security of the communication of the physical sensing device.

Description

technical field [0001] The invention relates to the field of Internet of Things devices, in particular to an Internet of Things gateway device and an access method thereof capable of safely authenticating physical perception devices. Background technique [0002] The Internet of Things is based on carriers such as the Internet and traditional telecommunication networks, and interconnects physical devices that can be independently addressed. The Internet of Things can be regarded as the use of communication technologies such as the Internet and local area networks to connect sensing devices, machines, and users, forming a new form of human-things, things-things connection. With the rise of the IoT industry, IoT technology has gradually entered production and life, bringing many new application forms from smart cities to smart factories to smart homes. and efficiency load issues are also increasingly prominent. [0003] The devices connected to the Internet of Things are not...
