What size initialization vector is used in WPA2?What size initialization vector is used in WPA2? CCMP uses 128-bit AES encryption with a 48-bit initialization vector.
What size is the initialization vector IV for the temporal key integrity protocol TKIP used in the WPA standard?WPA uses Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys by using a hashing algorithm and adds an integrity-checking feature that verifies that the keys haven't been tampered with. WPA improves on WEP by increasing the Initialization Vector (IV) from 24 bits to 48.
What is the bit size of the IV for WEP?Encryption details
Standard 64-bit WEP uses a 40 bit key (also known as WEP-40), which is concatenated with a 24-bit initialization vector (IV) to form the RC4 key.
How many possible unique IV's can the WEP protocol use?The IV being sent in clear text is vulnerable to attackers that can capture the encrypted frames and derive their content. An IV is 24 bits long and provides 16,777,216 possible values.
