Intelligent household equipment and system, and visitor password acquisition method

Abstract

The invention discloses an intelligent household equipment. The equipment includes a micro control unit (MCU) and a safety chip; the MCU is connected to the safety chip; the safety chip is used for receiving a generation visitor password management instruction sent by a remote server, and verifying the management instruction through a prestored public key certificate; and the safety chip is also used for generating a visitor password and storing after successfully verifying the management instruction, performing encryption on the visitor password through the prestored public key certificate and uploading the visitor password to the remote server. The problems in the prior art, that intelligent household equipment is easy to suffer external attacks so that passwords can be stolen and equipment safety is in danger, can be solved. A visitor password acquisition method, related equipment and a system are also disclosed.

Description

technical field [0001] The invention relates to a smart home device and system and a visitor password acquisition method. Background technique [0002] With the development of information systems and Internet of Things technology, some devices in daily life have become intelligent, such as: surveillance cameras, smart door locks, etc. Verification is used to ensure the safety of intelligent equipment and prevent illegal operations by unscrupulous personnel. Due to its convenient operation performance and advanced technical experience, intelligent equipment is changing people's quality of life and bringing people a convenient experience. People can control the smart device through password access by entering the target password into the smart device in advance. However, the currently used smart devices are connected to the network, and there is a risk of being attacked by the network. People's concerns about security have affected the popularity of smart devices to a certai...

AI Technical Summary

Problems solved by technology

However, the currently used smart devices are connected to the network, and there is a risk of being attacked by the network. People's concerns about security have affected the popularity of smart devices to a certain extent.

At the same time, in the current smart devices, the target password stored by the MCU is usually a fixed password, and the MCU has the risk of being attacked by the outside. If the MCU is attacked or accessed illegally, resulting in the leakage of the password, it will Threatening the user's work or living safety, bringing unnecessary troubles to the user's production and life

When a visitor needs to temporarily operate the smart device, inform the visitor of the fixed password. It may happen that the visitor uses the fixed password to operate the smart device multiple times without the knowledge of the manager of the smart device.
