How many keys does WPA2 have?
A WPA2 Pre-Shared Key uses keys that are 64 hexadecimal digits long. This method is commonly used on home networks.
What are the advantages of the dynamic encryption key as in WPA2 over a static key as in WEP )?
Wi-Fi Protected Access (WPA and WPA2) provides much greater security than WEP, but requires a separate authentication protocol, such as RADIUS, be used to authenticate all users. WPA uses a dynamic key that constantly changes, as opposed to the static key that WEP uses.
What is group temporal key?

Can WiFi password have symbols?
The shortest password allowed with WPA2 is 8 characters long. WPA2 passwords can be up to 63 characters long. Of course, it is better to include both upper and lower case letters along with numbers. WPA2 passwords can also contain a host of special characters.
What is the main difference between WEP and WPA?
WEP stands for Wired Equivalent Privacy, and WPA stands for Wireless Protected Access. WPA2 is the second version of the WPA standard. Using some encryption is always better than using none, but WEP is the least secure of these standards, and you should not use it if you can avoid it.
Is TKIP still used?
Temporal Key Integrity Protocol (TKIP /tiːˈkɪp/) is a security protocol used in the IEEE 802.11 wireless networking standard. However, TKIP itself is no longer considered secure, and was deprecated in the 2012 revision of the 802.11 standard. …

How is WPA2 used in the corporate world?
Wireless networks using WPA2-Enterprise security with 802.1X authentication are a common sight in corporate environments. It provides a secure way for devices to communicate over the air. While studying for the CWSP exam, I became familiar with the mechanisms of WPA2-Enterprise authentication.
What is the group integrity key for TKIP?
GIK (Group Integrity Key): Key used for data auth (used only by Michael for TKIP). Thanks for contributing an answer to Information Security Stack Exchange! Please be sure to answer the question.
Can a WPA key be reset to 3600?
Unless there is a specific need to lower the key renewal timer, 3600 should be fine (it is default for most routers) – as long as you have a strong WPA key. In case the router resets to the default values; this means all the changes are removed including the security settings and the server access password.
