Security companies should pay attention to the technical security of smart locks

HC Security Reuters childhood we are often the key hanging rope around his neck, swinging expect any key between walking home, the key to unlock the door of clicks also filled with childhood memories ...... now the era of intelligent locks are quietly Coming, maybe a few years later the children will play the mechanical lock as an antique.

The safety of traditional mechanical locks faces challenges

According to relevant data, about 60% of the current lock cylinders still use the marble lock cylinders that were popular in the 1990s. Due to their long circulation time in the market, most thieves have already mastered the internal structure of the lock and the principle of unlocking. The unlocking skills have been It can be described as a pure fire, and the unlocking time can vary from a few minutes to a few seconds. Such a lock is invisible in front of the thief, posing a serious safety hazard to the family. Most of the current locks are still A-class locks, and many locks for developers to pay for the fashion are A-class locks. This type of lock has only one row of marbles. The keys have only one row of card slots and one row of bullet holes. They can be opened with tools such as master keys and even wire and tin foil.

Smart locks are flying into the homes of ordinary people

Smart locks are the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The use of human biometrics for identity security identification and authentication means that it is irreplaceable, non-replicable and unique. It adopts high-tech digital image processing, biometrics and DSP algorithms, and is a new generation of access control that meets modern security requirements. Equipment, widely used in government agencies, banks, high-end apartments and other places that require absolute security and privacy. Compared with the traditional mechanical lock, the biometric lock is safer and more convenient. It can also integrate virtual password, anti-theft alarm, smart home and other functions to protect the anti-theft. Below we will introduce some of the more common types of biometric locks.

The fingerprint lines of different people are different in pattern, breakpoint and intersection, and they are unique and permanent. The fingerprint lock is to match the fingerprint with the person through the unique fingerprint feature of each person, and to identify the identity when opening the door. And because of the convenience, speed, accuracy and other characteristics to attract more and more audiences. In recent years, the development of fingerprint locks has also shown a variety of development trends: the number of fingerprint lock manufacturers is increasing; the product standards are gradually improving; the products are developing in diversified directions; the fashion elements in the appearance are more and more, and the real estate projects are also The market potential of pulling fingerprint locks.

But the fingerprint lock has other hidden concerns behind the seemingly beautiful scenery. First of all, the recognition rate of the fingerprint identification lock needs to be improved, because about 1%-5% of the people can not use the fingerprint lock, or need multiple recognition to pass, if the success rate of fingerprint recognition can reach more than 99%, the promotion difficulty It will be smaller and accept more people. Secondly, the battery life is different. The high energy consumption function, the scientific design of the circuit, the reasonableness of the leakage protection, the number of users and the frequency are all important factors affecting the power supply. . For the battery life of the fingerprint lock, the manufacturer generally indicates that it can be used for one year, but the lock can only be used for half a year, and the household owner will not be prompted to replace the battery before the battery is exhausted. Smart locks happen outside the door. Finally, some manufacturers have insufficient fingerprint lock stability. Therefore, when you are prompted to buy a fingerprint lock, you should purchase a regular manufacturer's product. Do not blindly purchase the standard.

The iris lock is also a member of the smart lock field that has to be mentioned. Iris lock is a kind of intelligent lock with human iris as the identification carrier and means. The gene expression of the human body determines the shape, physiology, color and total appearance of the iris. The iris morphology can be kept basically unchanged for several decades. On the other hand, the iris is externally visible, but at the same time it belongs to the internal tissue, behind the cornea. To change the appearance of the iris, it requires very fine surgery and the risk of visual impairment. The uniqueness, stability and unchangeable characteristics of the iris are the material basis for the identification of the iris. These features also make the iris recognition technology surpass the fingerprint recognition technology and become the most accurate identification technology for current applications.

However, iris locks also have their own drawbacks. For example, if a person has the right to unlock the iris at different occasions, its biological information is left in a different place, and the risk of being copied is increased. To resolve the risk, the password card must be applied at the same time. The use of irises with different PIN cards for locks reduces security risks, but at the same time it is less convenient.

The security problem of smart locks is also urgently needed to be solved by security companies.

Through the above illustration of the fingerprint lock and the iris lock, we can see that the mechanical lock has become safer with the use of various technologies, and the smart lock that will become popular in the future will one day take up the family guards. The burden of a line of defense, but we are also good at all kinds of smart locks, but also pay attention to the anti-destructive performance, network security, information security and other issues after the lock is intelligent. For the entire field of smart locks, we should pay attention to the following issues.

First of all, most of the smart locks circulating on the market are basically not subjected to secondary locking, so the lock core can be destroyed by tools such as a hammer, a knife, and a screwdriver. Secondly, in order to reduce production costs, most enterprises will not make a high-level encryption system, but only blindly speculate on "smart", but under such "intelligence" it is difficult to hide security risks. Researchers at the Weizmann Academy near Tel Aviv and Dalhousie University in Canada have experimented with Philips' Hue smart bulbs, and hackers can infect them without having to access them directly: researchers are 229 feet away from a building (about 70 The place where the car was driven by was enough to make the network inside the building infected with malware. Similarly, hackers can also disable smart locks through malware. Finally, when a hacker attacks a smart lock, it may also steal personal information including passwords, which is another security risk of smart locks. At the same time, because the smart latch is in the individual case of identifying failures, some smart locks will introduce two sets of unlocking schemes, and when the user can meet one of the schemes, they can enter the house, and their safety performance will be greatly reduced.

HC Security Network Conclusion: The progress of the times and the development of science have prompted our locks to be constantly updated, but the promotion of each kind of smart products requires developers to pay attention to the new security issues brought by the products. In the era of smart locks, our security companies must make more innovations in security technology, so that every family can use the security of the smart locks in the future.
