A method for improving public Wi-Fi network security based on WPA / WPA2PSK multiple passwords. The invention belongs to the field of information security. Limited by WPA / WPA2PSK, Wi-Fi networks in public places can usually only set a single public password at present. People within the coverage area can steal user information through packet capture and decryption, forged phishing APs, intranet packet capture, and intranet man-in-the-middle attacks, which will bring hidden dangers to user information security. The present invention sets multiple sets of different WPA / WPA2PSK passwords for users to use through a single Wi-Fi network. Users do not know other people's passwords and are isolated from each other, thereby preventing user data from being stolen and improving the confidentiality of Wi-Fi users surfing the Internet in public places And the security of online transactions, while keeping the user's hardware, software, and connection methods unchanged, ensuring compatibility with the original user-end equipment.

The invention discloses an ultra-thin non-woven fabric for cable and optical cable expansion water-blocking tape and a production method of the ultra-thin non-woven fabric. The ultra-thin non-woven fabric comprises a polyester fiber layer, through holes and a hydrophilic water absorbing expansion material. The upper surface and the lower surface of the polyester fiber layer are each provided withthe through holes. The hydrophilic water absorbing expansion material is arranged in the polyester fiber layer and on the upper surface and the lower surface of the polyester fiber layer. The ultra-thin non-woven fabric for the cable and optical cable expansion water-blocking tape is prepared by conducting opening, carding, lapping, carding again, hot rolling, puncturing, coiling and material soaking through a non-woven device. In this way, a cable rapidly expands when the cable encounters water and tidal gas enters the cable so that water can be prevented from entering, the safety effect is achieved, and the cost of a package material of the cable and the optical cable is greatly reduced.

The invention discloses a scooter tap position control system and a tap position control method thereof. The method comprises the steps: pressing a multifunctional button so as to enter a tap position setting mode; pushing and pulling a remote-control upper cover back and forth so as to adjust a movement tap position of a scooter to an expected tap position; pressing the multifunctional button again so as to exit the tap position setting mode. According to the scooter tap position control system and the tap position control method thereof, the multifunctional button is controlled by using fingers, the operation is convenient, the velocity of movement of the scooter is detected through monitoring a sensor moving component and a sensor fixing component, and a tap position of the scooter is controlled through pushing and pulling the remote-control upper cover; due to the provided technical scheme, the control is more user-friendly, a safe effect is achieved, and no additional operation and burden is increased.

A security terminal machine comprises a housing, a base-band processing and logic control circuit, a man-machine interface, a shielding housing, a high-frequency head, a built-in antenna, a high-frequency socket, a high-frequency plug, an antenna switch, a single shielded antenna, a dual-shielded antenna, a shielded antenna with three antennas, and an exposed antenna. The security terminal machine is different from a conventional terminal machine in that: high-frequency radio frequency and intermediate frequency circuits of the high-frequency head of the security terminal machine and all circuits generating electromagnetic waves are shielded and isolated by a metal radome, and strong harm of electromagnetic fields to a human body is avoided; and only a display or touch screen is not shielded. According to the invention, a plurality of shielded antennas are arranged, the electromagnetic waves are guided to the position far away from the human body for exchanging signals with a ground station, so that the problems of strong harm to the human body and blind areas of the conventional terminal machine are solved; in addition, only by inserting the exposed antenna into the machine, the security terminal machine can be used as the conventional terminal machine, the usage is very convenient, and a good effect is achieved.

The invention provides a heating type automatic control device and a control method thereof, which relate to artistic creation tools such as calligraphy and painting. It includes a heater body, one end of the heater body is provided with a heater head, and a heater core is fixed inside the heater head. A microprocessor control module is also arranged inside the heater body. Use the human body infrared sensor module to identify whether the user needs to start creating, to control the heating of the heater core in the device. When the human body leaves the device, it can provide a warning light flashing and a buzzer prompt, and automatically cut off the heating. If the human body tissue When approaching the heating core, there will be a rapid buzzing warning and a high-frequency warning light flashing, and the heating will be turned off at the same time, which achieves a safe effect while intelligently saving power.

The invention discloses a scooter speed control system with a safety mechanism and a control method. The method includes the following steps that: a finger is used to control a speed adjustment operation area to control the movement state of a scooter; a remote control upper cover is pushed and pulled backwards and forwards, so that the movement speed of the scooter can be adjusted; after the scooter moves, a sliding mechanism moves relative to a remote control lower cover; and a scooter speed detector monitors the induction signals of an inductor mobile component and an inductor fixed component. According to the scooter speed control system with the safety mechanism and the control method of the invention, the speed adjustment safety mechanism according to which the finger is used to touch the speed adjustment induction area, is adopted; only when the finger touches the induction area, and the remote control upper cover is pushed and pulled, the speed of the scooter can be adjusted, otherwise, the speed of the scooter cannot be adjusted, and therefore, operation is convenient; the movement speed of the scooter can be detected through monitoring the inductor mobile component and the inductor fixed component; and the operating speed of the scooter is controlled through pushing and pulling the remote control upper cover. With the scooter speed control system with the safety mechanism and the control method provided by the technical schemes of the invention adopted, control is more humane, a safety effect can be achieved, and any additional operation and burden are not increased.

A method and system for enhancing the security of a converged IP message, the method comprising: after adding sensitive attribute information in a CPM message to be sent by a converged IP message CPM client, sending the CPM message to a receiving terminal through a CPM system; the CPM system , and / or after receiving the CPM message, the receiving terminal performs subsequent processing on the CPM message according to the sensitive attribute information carried therein. Compared with the prior art, since the CPM message of the present invention carries sensitive attribute information, when the CPM message reaches the recipient, the recipient can perform subsequent processing according to the indication of the sensitive attribute information, thereby achieving the effect of information security and improving user experience .

A method, device, and storage medium for sharing and assigning frequency band resources between satellite communication devices, using the websocket protocol, including the steps: according to the relationship of "device ID-data type-user coloring mark", for satellite terminal devices obtained from satellite links including equipment The data of ID and data type is added with corresponding dye marks or default marks, which are used as permission marks and public marks respectively; broadcast the data to different websocket addresses according to the added dye marks or default marks; For data presentation, the websocket subscription refers to dynamically subscribed websocket addresses of authority data including authority tags and public data websocket addresses including public tags after a connection is established between the websocket server and the websocket client. It realizes the authority control with higher real-time performance and more flexible processing method, and improves the confidentiality and security of satellite network data transmission.
