The 14-year-old WPA2 encryption protocol has to say goodbye to everyone, because the next-generation wireless encryption protocol, WPA3, is expected to land on various wireless terminal devices by the end of this year. In October last year, it experienced WPA2 protocol vulnerability (logical defect). The little friend can finally feel free to arbitrarily free Wi-Fi, and my mother will never worry about your Wi-Fi security anymore.
How big is the market for renewal?
Although the Wi-Fi Alliance has officially launched the WPA3 encryption protocol, in fact, if you really want to use the device with this new encryption protocol, you still have to wait patiently. This is not only because the Wi-Fi Alliance has not announced which devices are supported. WPA3, and wireless vendors do not want to launch WPA3 only through firmware upgrades, so many do not (mei) plan (qian) count (zhuan).
How much does it cost to change a router/AP? It depends on how big the overall size of the overall wireless market is. According to IDC, the overall revenue of the global consumer and enterprise wireless LAN (WLAN) market in the first quarter of 2018 is as high as 2.24 billion US dollars. And this is only the revenue scale of this quarter, the previous wireless equipment market stock, the natural volume is even larger. In addition, statistics show that enterprise WLAN growth has maintained a steady growth of 5.7% throughout 2017. The rate also makes the wireless manufacturers earn a lot of money.
Therefore, although it is theoretically possible to implement WPA3 upgrade through firmware update, it is necessary to spend money to re-apply for WPA3 certification, and secondly, it is not profitable. So most wireless device manufacturers are more inclined to invest resources to develop new ones. Wireless hardware.
How long will it take to use WPA3?
Since the new generation encryption protocol WPA3 has emerged, when will the majority of users use it? It is reported that Qualcomm has already produced new wireless chips supporting WPA3 for mobile phones and tablets, but it will take some time to integrate into new devices. Cisco has also announced that it will provide WPA3-enabled devices. However, all of these devices must be certified by the Wi-Fi Alliance to be labeled as 'Wi-Fi CERTIFIED WPA3'.
According to the Wi-Fi Alliance, devices that support WPA3 will be unveiled at the end of 2018, and everyone should look forward to it.
It is important to note that in order to obtain WPA3 next-generation wireless encryption, you must not only have a wireless router that supports WPA3, but also client devices that support WPA3, such as laptops, mobile phones, and other wireless terminals, in order to play WPA3 security. Advantage.
Once all devices support WPA3, you can create a more secure wireless connection by disabling WPA2 encryption on the router, just like disabling WPA and WEP connections.
How much is WPA3 encryption?
First, WPA3 supports 'Wi-Fi Enhanced Open' technology to improve the security of public Wi-Fi connections. When the terminal is connected to an open Wi-Fi network, the technology's Opportunistic Wireless Encryption algorithm is used. Even if you do not enter a password when connecting, the traffic between the device and the Wi-Fi access point is encrypted. This will make the public open Wi-Fi network connection more private.
Secondly, it can prevent brute force cracking. WPA3 encryption uses the equal value simultaneous authentication (SAE) algorithm instead of the PSK algorithm in WPA2. In the attack scenario of Wi-Fi, usually the attacker will use the automated tools to quickly and continuously try each A password is used to guess the password of the Wi-Fi network. The SAE algorithm can effectively prevent this brute force cracking method and block the authentication request after multiple attempts to verify the failure.
In addition, the risk of leakage caused by traffic monitoring is prevented. Due to the use of WPA2 and previous encryption protocols, devices can be attacked by man-in-the-middle attacks and tamper with communication content. However, WPA3 introduces a 'Forward Secrecy' mechanism to ensure Session key independence, even if an attacker gets a Wi-Fi password, it can't decrypt the traffic of other users on the network, and the security is greatly improved.
Finally, it simplifies the security configuration. WPA3 also adds the 'Wi-Fi Easy Connect' feature for quick and secure access to wireless networks for smart speakers, smart sockets and smart light bulbs without a keyboard and display. And I heard that the follow-up will also introduce this feature on the WPA2 protocol.
current,
Regardless of the open Wi-Fi network that can be found in airports, hotels, coffee shops and other public places, the traditional encryption protocols below WPA2 are used, which leads to certain security risks. I believe that with the new generation of WPA3 wireless encryption protocol Come, everyone's Wi-Fi security can be further strengthened and become more secure. So, will you buy new equipment for wireless communication security? If you have nothing, you can think about it in advance.
