Abstract

The invention provides an Internet of Things terminal safety protection device and method and relates to the technical field of safety protection. The Internet of Things terminal safety protection device comprises an intrusion detection circuit and a safety module, wherein the safety module comprises an intrusion detection circuit interface, a signal filtering circuit, a safety chip and a communication interface; the security chip performs communication data interaction with the functional circuit through the communication interface; the intrusion detection circuit detects whether a Mesh circuit on the Internet of Things terminal is damaged or not and whether the Internet of Things terminal is disassembled or not to generate an intrusion signal, and sends the intrusion signal to the signalfilter circuit through the intrusion detection circuit interface; the signal filtering circuit is used for filtering the invasion signal; and the security chip receives the filtered intrusion signal,and clears security data stored in the security chip based on the filtered intrusion signal. According to the device, high response real-time performance of the intrusion signal can be realized, false triggering can be prevented, safety of important data of the Internet of Things terminal is improved, and reliability is high.

Description

technical field [0001] The present invention relates to the technical field of safety protection, in particular to an Internet of Things terminal safety protection device and method. Background technique [0002] At present, various terminals related to information security, although some terminals have a passive mechanical anti-tampering mechanism, they do not have the intrusion detection function. The detection module is not directly connected to the security chip, so that the security response of the terminal is low in real time and poor in reliability. Therefore, regardless of whether the terminal adopts a mechanical tamper-proof mechanism or a simple intrusion detection method, it will bring serious security risks such as important data leakage to the terminal and reduce the stability of the terminal. Contents of the invention [0003] The purpose of the present invention is to provide a security protection device for an Internet of Things terminal, so as to alleviat...
