According to media reports, hackers steal passwords for home WiFi through smart water bottles, which makes the security of smart home products using WiFi technology return to the public's field of vision.
This is an experiment done by a foreign technical team. The object of the experiment is a smart kettle that can be remotely controlled by a specific smartphone application. The technician only uses some social worker data, directional antennas, and some network devices to easily obtain the WiFi password currently accessed by the smart kettle. The technician can then locate the user's geographic location by intercepting the WiFi password, intercept the user's router, and even hijack the victim's device to a malicious website, implanting malware into their device. It can be seen that the hacker breaks the user's home WiFi network through smart devices, and the consequences are bad.
The issue of smart home security has always been one of the most concerned topics for users. Although smart homes can bring convenience to users, first of all, we must ensure the safety of users at home. Is WiFi suitable as a communication technology for smart homes? Everyone has their own opinions. The large amount of WiFi users, the wide range of popularization, and the ease of use are the advantages of WiFi, but security issues cannot be guaranteed. Here, in fact, there is no need to enumerate the encryption technology of WiFi, and there is no need to list news similar to WiFi being hacked. There are such cases around us. Uninformed, the phone connected to the unfamiliar WiFi, causing the user's traffic to be lost for no reason. If the smart home products using WiFi technology are attacked, the damage will be even more serious.
In fact, at the 2015 Internet of Things and Smart Home Global Summit Forum, the Internet of Things Internet Café also discussed the issue of IoT smart home security. Zhu Jungang, president of IOT, also mentioned WiFi technology. In the current smart home industry , many companies choose WiFi modules. From a technical point of view, the security of WiFi devices cannot be guaranteed. Especially in the smart home field, if WiFi is attacked, then the home appliance may be controlled by others, and there is no secret in user privacy. WiFi also has hidden dangers in many aspects such as device carrying capacity, power consumption, and health. As far as the current status of WiFi is concerned, WiFi is not an excellent solution for solving smart home systems .
In addition to withstanding the test of security, WiFi technology must withstand the test of power consumption, equipment carrying capacity, health and so on. In terms of power consumption, WiFi power consumption is currently the most energy-consuming in wireless technology, and it will cause more trouble for users in the smart home field. Moreover, the number of devices carried by WiFi is limited, and it is impossible to assume more intelligent devices for building a complete smart home system. In terms of health, it may also pose potential hidden dangers for users. As mentioned by Mr. Zhu Jungang, President of the Forum on the Internet, although the current threat to WiFi has not been exposed, the WiFi radiation is large. When there are more WiFi devices in the home, even if there are many WiFi devices in each household, The damage to human radiation is enormous.
WiFi wants to become the mainstream smart device module, many of the problems mentioned above are the challenges that WiFi has to face. Moreover, at the 2015 Internet of Things and Smart Home Global Summit Forum, many experts and scholars have identical views on IoT communication technology. Everyone agrees on the advantages of ZigBee technology in the Internet of Things industry, especially the impact and change brought to the smart home industry. Moreover, ZigBee technology is also the first choice of many smart device manufacturers. For example, the world's top 500 Philips, using ZigBee technology to bring changes to the user's lighting. The well-known smart home manufacturer in China, and also a member of the ZigBee Alliance Board of Directors, is the promoter of ZigBee technology in the Chinese market. IoT has widely used ZigBee technology in its smart home systems. Practice has proved that ZigBee has truly played its advantages and has obvious advantages over WiFi technology.
In the existing market, WiFi has a lot of competitors, and WiFi is facing more tests. When it can provide good security, it is the first step for WiFi to enter smart home. Moreover, under the impact of the prior art, when will WiFi be able to stand in the smart home industry?
