Now the WPA2 security protocol for large-scale use has been cracked for a long time and the security of WiFi has been precarious. Finally, the WiFi Alliance announced the WPA3 encryption protocol, which has improved the Internet of Things, improved the encryption strength, prevented violent attacks, and public WiFi. Great security. Finally you can rest assured that you can use WiFi to access the Internet. To enjoy the most secure WiFi network, wireless devices in your hands must exchange blood.
The market is incalculable Consumer-grade products prior to enterprise-level deployment
Since the formal commercial use of WiFi in 2002, it has experienced 16 years of development. There is no accurate device number in this market. However, according to the data released by the WiFi Alliance, there are currently a few billion devices using the WiFi connection network. Visible WPA3 The wave of equipment replacement will be a huge market.
At present, Qualcomm said that it will first support the WPA3 encryption protocol in the Xiaolong 845 chip in June. Other devices that support the WPA3 protocol will be announced at the upcoming Computex exhibition. On devices that support WPA3, there will be 'WiFiCertifiedWPA3'. Labels. Devices that support the WPA3 protocol will be backwards compatible with the WPA2 protocol. However, to support the WPA3 protocol upwards, new devices will need to be replaced. Given that many users rarely care about the security of routers, the adoption of the WPA3 protocol requires widespread adoption of devices. a period of time.
WPA2 loopholes cause serious consequences for people
'Set WiFi password'
'Select encryption method WPA2'
I believe that friends who have set up a wireless router must be very familiar with the above two steps. However, since the WPA security protocol was cracked for several years, WPA2 was also cracked last year. Hackers can crack WPA2 security through a security hole named 'KRACK'. The agreement to get the wireless router's WiFi password.
Every day, billions of devices around the world use the WPA2 security protocol. The consequences of being compromised are unthinkable. However, from the user to the vendor, no measures have been taken against WPA2 being cracked. Even many people do not know that WPA2 has been Crack, still think it is the most secure encryption protocol. The user did not modify the password of their own routers, 12345678 is still the most used password in 2017. The manufacturer also upgraded the firmware of the next product, telling the user that the vulnerability has been blocked.
To know that the KRCK attack directly affects the wireless router as the hub of the home network, this is more terrible than the virus on the PC. The attack on the PC, the service provider will promptly push the latest repair patch to protect the user from attack. In the home and small micro There are no such repair capabilities at all over the enterprise's hundreds of millions of routers or APs. On the other hand, after users install the router, they rarely go to the management background to upgrade the device. They cannot update the latest firmware to protect themselves. Security.
WPA3 Debuts Four Major Safety Improvements
Fortunately, the WiFi Alliance is still working hard for users to use WiFi securely. The organization recently announced the WPA3 encryption protocol, the new WPA3 encryption protocol will bring four major security improvements.
1. More powerful encryption algorithm. WPA3 has a stronger encryption algorithm than WPA2. It can deal with security encryption applications in the industrial field, defense field and government field.
2. Prevent brute-force cracking. WPA3 will not be attacked by KRACK because of the Dragonfly protocol. And WPA3 strictly limits the number of users guessing WiFi passwords. Hackers use their own 'dictionaries' to brute force password attacks. invalid.
3. Improve the security of IoT devices. Nowadays, more and more smart home devices are connected to wireless routers. WPA3 supports one-click settings, and networking can be achieved only by pressing a button, making IoT devices more securely connected.
4. Protect public WiFi. WiFi in public places such as airports, coffee shops, and shopping malls does not require a password connection. There are security concerns, but many people do not care about its security. WPA3 uses special encryption technology to allow access devices. The connection to the wireless router has a unique key. Even with open WiFi, the data transmitted between the device and the router will not be exposed to the network.
Conclusion: The emergence of the WPA3 security protocol will undoubtedly make WiFi more secure. However, the WPA2 protocol will also co-exist with WPA3 for a long time. Although there are still many people who do not take WiFi security seriously, as a standard for the WiFi Alliance mandatory certification, With the constant replacement of user equipment, WPA3 will penetrate into everyone's devices.
