Abstract

The invention relates to an Internet of Things smart home security gateway system. The system comprises a user side, a security gateway and a terminal node. The user side and the terminal node each comprise a data encrypting / decrypting module used for encrypting / decrypting a sent control order and received data through a preset encrypting program on a remote client side or the terminal node; the security gateway comprises a safety communication module, a user access control and node identity authentication module, a credible platform module and a log audit and alarm module; the safety communication module achieves data safety filtering, reconstructing and forwarding and guarantees safety of the bi-direction transmission; the credible platform module is used for achieving system safety authentication, user behavior credibility analysis, data sealing storage and free decoupling and can be independently maintained and upgraded; the log audit and alarm module is used for recording user access and node authentication behaviors, carrying out safety audit on the operation of viewing logs and giving a timely alarm for an abnormal phenomenon found in the gateway system safety monitoring process. By means of the Internet of Things smart home security gateway system, the safety performance of a smart home system and the running efficiency of a gateway can be improved, and a safety guarantee is provided for Internet of Things smart home.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things network security measurement and control and trustworthiness, and relates to an Internet of Things smart home safety gateway system. Background technique [0002] Existing smart home systems mainly focus on remote or local control of household devices and indoor environment monitoring based on Internet of Things technology. They have not yet provided guarantees for information transmission security, control security, and user privacy. There are security risks and are vulnerable to attacks. As the control center of the smart home system, the gateway is the necessary node for external attacks to enter the smart home system. It is responsible for the core task of information exchange inside and outside the network. It faces many security threats from outside the smart home system. Home system access control, a key part to ensure the security of smart home systems. On the other hand, limit...
