4-way handshake of WPA
When the WPA system is working, the AP first publishes its own WPA support to the outside, and uses the newly defined WPA information element in beacons, probe response, and other reports ), these information elements contain AP security configuration information (including encryption
Enable WPA certification support on UbuntuLinux-Linux Enterprise Application-Linux server application information. For more information, see the following. Applicable environment: Ubuntu Linux "Dapper Drake" 6.06 LTS

very secure, so we can try to use the WPA2 encryption method to improve the security of the wireless network. More security protocols related to WPA2 will be launched in the future, such as more reliable standard wpa xp, wpa kb Preview, WPA beta official version, and WPA official version SP1, these standards and proto
universal key. WPA also adds functions and authentication functions to prevent data tampering in the middle. With these features, the disadvantages of WEP that were previously criticized have to be completely solved.
WPA includes temporary Key Integrity Protocol (Temporal Key Integrity Proto)Col, TKIP) and 802.1x. Together with 802.1x, TKIP provides dynamic key
long period of time, and users will not just for the security of the network to abandon the original wireless equipment, so the wireless industry Alliance before the new standard launch, but also on the basis of the 802.11i draft WPA (Wi-Fi procted Access) Wireless encryption protocol. WPA uses TKIP (temporal key Integrity Protocol, Temporal Key Integrity Protocol), and its encryption algorithm is still t
With the gradual maturity of wireless technology and the popularization of the price of wireless devices, more and more families are using WLAN to surf the Internet anytime, anywhere. However, the network security problem also emerged. Although some users with certain computer and network security levels began to use WEP or WPA keys to encrypt transmitted data packets, WEP cracking is quite easy, it is said that foreign professionals can intercept WEP
. Here the specific input commands are as follows:Parameter explanation:-0 using Deauth attack mode, followed by the number of attacks, here I set to 1, we can be set according to the actual situation of 10;-A followed by the MAC address of the AP;-C followed by the client's MAC address;When you enter, you will see the display of the Deauth message sent as shown in 26.Figure 26At this point back to the Airodump-ng interface view, in 27 we can see the "WPA
Configure WPA encryption in tp link 802.11n to improve Wireless Network Security:
Currently, WPA is the safest way to encrypt wireless networks, and there are no solutions to this problem, so at the end of this article, I will introduce how to configure WPA encryption in the tp link 802.11n package to improve wireless network security.
Tip: In our tp link 802.11n
signals. 3. Click wireless security settings-select WPA-PSK/WPA2-PSK.(1) authentication type: automatic selection, WPA-PSK, WPA2-PSK, the three are basically no difference. (2) encryption algorithm: automatic selection, TKIP, and AES. We recommend that you use the AES encryption algorithm. If you select TKIP, the following interface is displayed, it is prompted
First, WPA introduction
Wi-Fi Protected Access (WPA) is a protocol and algorithm for improving the security of the keys used by WEP. It changes the way the key is generated and transforms the key more frequently to get security. It also increases the message Integrity check feature to prevent packet forgery. The function of WPA is to replace the existing WEP (Wi

Explanation: WPA is a standards-based, interoperable WLAN security enhancement solution that greatly enhances the level of data protection and access control for existing and future wireless LAN systems. WPA is derived from the ieee802.11i standard being developed and will be maintained forward compatible. When deployed properly, WPA guarantees that da
Currently, WPA encryption Wireless network is the most secure, there are no solutions, so this article describes how to configure WPA encryption in the TP link 802.11n suite to enhance wireless network security.
Tip: In our TP link 802.11n Suite, the wireless router provides an encryption method called WPA/WPA2, but this way of encryption requires a RADIUS serve

Failure phenomena:The two SSID emitted on the same AP, but the two SSID is in a different network interface, but it is found that the user will have a 54M rate when connected to the SSID1, but if the client is connected with SSID2, then the 11n or 11a rate will occur.Problem Analysis:First of all, see why all users Only connect to SSID 1 will appear 54M, because the network protocol is connected to 11a, and the connection to the SSID 2 will occur after the rate of 108m, because the network proto

Have you ever wondered how to make your wireless network more secure? Some people say that a large amount of information about Wi-Fi security can be found on the Internet, such as using WPA or WPA2, disabling SSID broadcast, and changing the default settings. However, this alone is not enough. We will share with you four advanced technologies that make wireless networks safer.
1. Switch to enterprise-level encryption

In a wireless WPA encryption environment, after obtaining a WPA handshake verification package, attackers can use the brute-force cracking mode to crack WPA passwords. In addition, they can also establish targeted dictionaries in advance, and then conduct dictionary cracking (attacks ). This will be an effective method for most Wireless Access Point APs. It turns
