Bluetooth smart lock how to use? Bluetooth smart lock safe? Bluetooth smart lock is also a major branch of the smart lock series. Users can conveniently control the door lock function through Bluetooth. In the continuous exploration and development of smart locks, there have been many new technologies and new products. Bluetooth smart locks that are attracting attention are among them. Users can check whether the locks are closed at any time, and can also implement cloud key sharing functions.
After the user selects the corresponding key on the mobile phone side, the mobile phone is vertically close to the door lock, and then the vertical mobile phone is rotated by 90° to realize the door opening. Is this novel? If the user forgets to carry the mobile phone or the mobile phone happens to be out of power, the door lock is also equipped with a touch screen, and the user can unlock according to the previously set 4-8-digit Arabic number password, and there is no problem.
If there is a visitor in the home and no one happens to be in the house, there is no need for a long time behind the pit. The digital key of the Bluetooth smart door lock can be shared with the guests. When the guest opens the door through the shared key, the device can notify the user. , Then the user can cancel it. Of course, the user can also specify that the shared key should be used at a predetermined time. If it is not reached or is out of date, the key cannot be used for opening the door.
In addition, a key can be used to unlock multiple locks, and the number of users holding the key is not limited, but the lock can only store up to 12 different sets of access codes.
Of course, each manufacturer's product use is different, please refer to the specification for details.
How Bluetooth Smart Lock WorksBluetooth technology is a short-range, low-cost wireless connection technology. It is an open interface system that enables wireless transmission of voice and data. Bluetooth devices operate in 2.4GHz industrial, scientific, and medical frequency bands, and this band can be used without application.
The use of Bluetooth technology not only effectively simplifies the communication between mobile communication terminal devices such as PDAs, laptops, and mobile phones and mobile phones, but also successfully simplifies the link between the above electronic devices and the Internet, thereby enabling these modern communication devices. Data transfer with the Internet has become more efficient and efficient.
The Bluetooth lock is mainly used for real-time monitoring of the working status of electronic devices (such as database devices) equipped with vital data and various information security control devices, whether they are being moved or attacked.
The system has the following main functions: 1) It can be embedded in the monitored system; 2) When the system is attacked or moved, it can notify the monitoring center and issue an order to destroy the vital information module; 3) Inform the monitoring center in time Effective information and control status; 4) Ability to identify the monitoring object; 5) Perform ciphertext query on the monitoring target working status; 6) Use full-duplex communication.
Compared with traditional door locks or combination locks, one of the innovations of smart door locks is through Bluetooth technology, with smart phones and supporting applications, open the door directly through the phone. The main advantage of smart door locks is that door lock management and remote authorization opening can be achieved.
One-touch cell phone binding, full cell phone management, convenient and efficient humanization; expired permissions automatically expire, renewal automatically generate new permissions; permissions at any time manually recovered, renewal or new lease re-issued permissions; assign real-time permissions or apply for temporary Password, want to see the look at that, the work efficiency is increased by 200%; the password is assigned by the mobile phone, the password is replaced by the whole password; the corporate background, the user automatically orders online to obtain the time password; use the phone to unlock or unlock the password, go out without having to Key;
Bluetooth smart lock security performanceSecurity is a complex issue that needs to be combined by many factors, including mechanical components and combinations, electronic components and combinations, network and transmission process control, system security settings, usage methods, and habits. The safe use of smart locks. The security problem of Bluetooth Smart Latching also exists in non-Bluetooth locks.
For example: Fingerprint lock fingerprints can be copied, Wi-Fi is decoded, password cracking, mechanical lock cylinders are easily opened, the lock panel can be easily opened and other issues, and other smart locks also have problems.
The security of the Bluetooth lock, in addition to the security issues of the Bluetooth transmission and reception process, there are also many other security issues. Therefore: a high-end security smart lock in addition to electronic information encryption and decryption, there are a lot of work to do well, otherwise the security is also useless.
According to Digital Trends, at the annual DEF CON hacking conference held in Las Vegas, two researchers found that 75% of Bluetooth low energy smart door locks are vulnerable to hackers. What is even more disturbing is that problematic manufacturers such as Ceomate, Vians, Quicklock, etc. do not show due importance to the safety issues of their products.
Anthony Rose and Ben Ramsey were the two researchers who discovered the problem. They tested 16 different Bluetooth smart door locks and found that 12 of them have varying degrees of wireless authority that can be obtained by hackers; some brands Wireless permissions are easily accessible, while others are relatively difficult. Among them, 4 smart door locks can easily reveal passwords under the attack of hackers. Quicklock’s Doorlock and Padlock products even send passwords to hackers several times, and allow hackers to modify the original passwords so that the owner cannot use the locks. .
According to Rose's disclosure to Tom's Guide, he and his partner contacted 12 smart lock manufacturers after discovering vulnerabilities, but these manufacturers did not care about the problem of loopholes.
Bluetooth Smart Lock How to Avoid Security VulnerabilitiesFor users who have purchased a problematic Bluetooth smart door lock, Rose recommends shutting down the Bluetooth connection on the smartphone when not in use. He also said that when manufacturers make Bluetooth smart door locks, the priority is physical security, not wireless security.
