Which brand of smart lock is the best and most secure? Caddis, Huawei, Deschmann, Xiaomi, Luke

What is the key to smart lock security?

1. Physical security

The physical structure and material of a smart lock are crucial to its security. Good smart lock are made of high-strength alloy materials, strong and durable, even if someone wants to use brute force to open the lock, it is not easy to succeed. And the lock tongue needs to be longer and harder so that it can be firmly inserted into the door frame and not easily opened.

2. Encryption technology

Communication encryption: Smart locks usually communicate with mobile phones and other devices wirelessly, such as Bluetooth, NFC, etc. In order to prevent information from being stolen or tampered with during communication, strong encryption technology is required. For example, some smart The lock uses NFC technology, which not only encrypts the information channel, but also uses fingerprint recognition to confirm whether the owner is operating it, which is safer.

3. Identity authentication mechanism

That is, how to prove that you are you,There are several methods in smart locks. The most common ones are fingerprint recognition and password. It needs to be set more complicatedly. Do not set it to 123456 for your convenience.It is also convenient for others, including using cards to open doors, vein identification, etc.

Of course, these alone are not enough, there must be ways to deal with those who want to sneak around. For example, it must be able to prevent someone from copying your key or authentication information; it must be able to detect someone trying to reuse previous authentication information to open the door; and it must be able to resist those who keep trying passwords. If they try too many times, the lock will It has to automatically alarm or lock for a period of time.

4. Anti-attack ability

Anti-repeated attacks: Smart locks need to be able to detect and prevent repeated attacks, i.e. prevent The attacker repeatedly sends previously captured authentication information to open the lock. Technologies such as timestamps and random numbers can be used to prevent repeated attacks.

Anti-brute-force cracking: Smart locks need to be able to resist brute-force cracking attacks, such as trying a large number of passwords, fingerprints and other authentication information to open the lock. Technologies such as limiting the number of authentications and alarming can be used. Prevent brute force attacks

This involves the strength of the software. This is why everyone buys smart locks from big brands. Small brands of smart locks do not have so much money invested in this. stage.

5. Software security

APP security: For smart locks controlled by mobile APP, APP security It is very important. The APP needs to be securely hardened to prevent reverse engineering, tampering, etc. The mobile APP we use and the software in the lock must also be safe and updated frequently to prevent loopholes from being exploited by bad people. In this way, our smart locks can truly protect our homes. Our security.

From the above five aspects, a safe smart lock must firstSolid materials, this is at the physical level. Secondly, it must beHigh-quality hardware configurationTo support, finally, there must be strong R&D and software capabilities StrengthTo ensure security in terms of algorithms, software, and networks.

So, such a smart lock is destined not to be too cheap, and it must be a big brand to meet the requirements. It is recommended to pay attention to the following 5 brands

1. Kaadas

Technical advantages: Kaidis smart lock uses advanced encryption technology, which can effectively prevent information leakage and hacker attacks. Its products have a variety of unlocking methods, such as fingerprint recognition, password unlocking, mobile APP remote control, etc., to satisfy users Different needs.

Lock cylinder and material: It adopts C-level lock cylinder, which is the type of lock cylinder with higher security level at present and has strong anti-prying, anti-drilling and anti-smashing properties. The lock body is mostly made of high-quality metal, which is strong and durable and can resist violent opening. For example, some high-end products of Caddis are also equipped with anti-pry alarm devices, which will immediately sound an alarm when the lock body is pried by external force.

2. Dessmann

Intelligent protection: Deschman smart locks do a very good job in security protection and have a variety of intelligent alarm functions, such as trial and error alarms, anti-pry alarms, etc. Once someone tries the wrong password multiple times or uses violent means to pry, Lock, the door lock will automatically sound an alarm and notify the user in time. Chip and algorithm: Its products adopt national secret algorithm security chips, which can effectively resist electromagnetic interference attacks such as small black boxes, ensuring the normal use of locks and user information security . Moreover, Deschmann\’s fingerprint recognition technology is also relatively advanced, with fast recognition speed and high accuracy, and can quickly and accurately identify user fingerprints.

3. Xiaomi

Data security: Xiaomi smart lock focuses on product safety and stability, using advanced technology and materials in terms of data transmission and storage. , has strict encryption measures to ensure user information security. For example, Xiaomi smart door locks can be connected to Mijia APP through the APP. The status and operation records of the door lock can be viewed in real time, while the safe transmission of data is also ensured.

Lock body structure: The lock cylinder of Xiaomi smart lock is also a C-level lock cylinder, and the main control chip is located on the rear panel, which can effectively prevent riots and demolition. and electromagnetic interference. Intelligent sensors are also added around the lock tongue, which can alarm in time if the door is not closed tightly or is left open.

4. Lockin

Identification technology: Luke Intelligence The lock uses advanced fingerprint recognition technology and encryption algorithms to ensure home security. Its fingerprint recognition module can quickly and accurately identify user fingerprints, and has a strong ability to identify fake fingerprints, effectively preventing fingerprints from being copied or forged.

Linkage protection: Luke also provides a wealth of intelligent linkage functions, which can be linked with smart cat eyes, smart doorbells and other devices to achieve all-round home security protection. For example, when someone stops at the door, the smart cat eye will automatically capture photos or videos and send the information to the user\’s mobile phone, allowing the user to understand the situation at the door at any time.

5. Huawei

Encryption and authentication: Huawei smart door locks have built-in EAL4+ security chips, adopt national secret algorithms, have financial-level security protection, and can prevent hackers box attack. At the same time, Huawei\’s smart door locks can be remotely managed through the Huawei Smart Life APP and linked with HILink devices to facilitate users to operate and manage door locks.

Door lock design: The keyhole of Huawei\’s smart door lock is under the panel. It has a safe and riot-proof design, and supports multiple methods such as one-touch unlocking with a mobile phone, fingerprint unlocking, password unlocking, etc. It is easy to use and has high security performance.
