Wi-Fi can be described as common in modern life, and even become a basic public Internet service in many restaurants, hotels and other places.
However, the security problems of Wi-Fi in these years are also getting more and more serious. The probability that WPA2 encryption that has been used in the 802.11 protocol for 13 years has been cracked is getting higher and higher.
According to ZDNet reports, Wi-Fi Alliance announced on Monday, The popular WPA3 encryption protocol will be available by the end of this year.
WPA3 encryption to enhance the main three points:
1, For open Wi-Fi scenes without encryption in cafes, restaurants, etc., the communication data of each device will be encrypted;
2, increasing the difficulty of dictionary password violence cracked, at the same time, if the password repeatedly wrong, will lock the attack;
3, using the new handshake retransmission method to replace the WPA2 four handshake.
Last October, WPA2 completely cracked the news spread like wildfire, the loophole is that an attacker can by inducing multiple installation of the same key, thereby resetting the random number and replay counter used by the encryption protocol, that is, although Do not know the password, but the password is rewritten as 0, to achieve crack.
As with any previous encryption method, WPA3's popularity will inevitably have a pain, that is, the old router and new device compatibility issues.
