1. Access WiFi 1.1 wireless peer-to-peer Security WEP (Wired Equivalent Privacy) WEP adopts RC4 symmetric encryption technology at the link layer. The user's encryption key must be the same as the AP's key to allow access to network resources, thus preventing unauthorized user listening and unauthorized user access. WEP provides a 40-bit and 128-bit key mechanism, but it still has many defects. For example, all users in a service area share the same key, if a user loses a key, the entire network

environment and in public places. Another way is to keep the key unchanged, which makes the user vulnerable to attacks. Due to interoperability problems, academic environments and public places have never been able to use proprietary security mechanisms. The most powerful wireless encryption technology "WPA2" WPA2 is an IEEE 802.11i standard authentication form verified by the WiFi alliance.

famous tables is Rainbow.Tables is a rainbow table that is often mentioned in the security community. It uses the lm/NTLM hash column of the Windows User Account as the cracking object. WPA-PSK hash tables Tables creation is not as easy as you think. In terms of creation itself, tables is very inefficient. In addition, you need to specify the pre-attack AP.To create a set of WPA-PSK hash for all common ac

WPA2-PSK (AES) of wireless network encryption technology) After the publication of 802.11i, the Wi-Fi Alliance launched WPA2, which supports AES (Advanced Encryption Algorithm). Therefore, it requires new hardware support, it uses CCMP (full code protocol for block Chain messages in counter mode ). In

places have been unable to use WEP. The disadvantage of WEP is that its encryption key is a static key and not a dynamic key. This means that in order to update the key, IT personnel must personally access each machine, which is not possible in an academic environment or public place. Another option is to keep the key unchanged, which makes the user vulnerable to attack.

LAN authentication, you can use WPA2 to ensure the confidentiality and integrity of wireless data. If WPA2 is not deployed, for example, because of legacy devices, WAP is used. 802.1X is recommended for use with WPA/WPA2 because it not only provides user authentication support, but also provides an automatic key distribution mechanism. If 802.1X is not deployed
