Which wireless communication protocol is best for smart homes ? ZigBee is doing what you want. In recent years, in order to compete for the potential of the smart home market , the debate surrounding various wireless protocol standards is constant, but it is undeniable that ZigBee has earned enough attention and is highly regarded and trusted. In the smart home field, compared to Bluetooth, WiFi, Z-Wave, RF and other technical agreements, ZigBee has always been dazzling, and there are few negative news. It is well-known and well-received, and many people have defaulted to the most suitable smart home agreement. standard.
The reason for this is that it is inseparable from the ZigBee protocol itself, and on the other hand, thanks to the strong enthusiasm and publicity of some companies.
——Technology, ZigBee is not born for smart home, but long for smart home. Smart home equipment needs to have sufficient security, stability, operational fluency, strong equipment carrying capacity and low power consumption, and ZigBee can meet and meet the requirements, so even ZigBee is mainly used in industry. The field now does not affect its charm in the smart home field.
—— At the promotion level, many well-known companies have adopted them, and some powerful companies have vigorously promoted them. If some people in the village use the ZigBee protocol, you may sneer at it, huh, no words, let alone trust, but if Samsung, LG, Texas Instruments, Logitech, Philips, Xiaomi and other well-known companies have adopted it? Will ZigBee feel good? Not only that, but the vigorous promotion of some companies is also very important. For example, members of the ZigBee Alliance Board of Directors and the early adopters of ZigBee’s IoT leader, IoT Sensing, will emphasize ZigBee’s advanced encryption algorithm in terms of promotion and security. Consumers are deeply rooted and have established a good reputation for ZigBee, thus promoting the development of ZigBee in China.
Therefore, no matter from which point of view, the ZigBee protocol has sufficient reasons to be welcomed by smart home manufacturers. However, just after the ZigBee Alliance announced that Samsung's brand SmartThings became a member of the board of directors after the IOT Sensing, less than a week, the Black Hat Conference poured a cold water, cool and cool cold water: smart home using ZigBee protocol There is a serious vulnerability in the device.
It is said that security researchers (Cognosec) have found that there are serious vulnerabilities in the devices using the ZigBee protocol. How serious is it? Hackers have the potential to invade smart homes, manipulate networked door locks, alarm systems, and even switch lights. According to past news, this kind of thing should happen to WiFi, Bluetooth or Z-Wave. How did ZigBee recruit?
——Black Hat Conference is recognized as the world's highest level of information security industry and the most technical information security conference. Every year, many professional teams and private experts participate. They can enjoy all the technology products, no need to be merciless, of course, the purpose is to exchange technology and improve the safety of enterprise products. Cognosec published a paper at the conference, pointing out a flaw in the implementation of the ZigBee protocol. The company said the flaw involved multiple types of devices, and hackers could harm the ZigBee network and "take over control of all connected devices within the network."
- If it is Cognosec, it will not be the case, especially the problem is very good - "Black Hat Conference broke the news, there are serious loopholes in the smart home equipment using ZigBee protocol" (the specific content please Baidu brain supplement), the reader can not see It doesn't matter if you look at the content. Just look at the title and you will understand: ZigBee smart home devices have serious vulnerabilities.
Description of Stacked D-Sub I/O Connectors
