proposed TKIP (Temporal Key Integrity Protocol) or AES (Advanced
Encryption Standard) encryption schemes are applied.
TKIP: TKIP uses an encryption algorithm which is more stringent
than the WEP algorithm and also uses existing WLAN calculation
facilities to perform encryption operations. TKIP verifies the security
configuration after the encryption keys are determined.
AES: AES is a symmetric 128-bit block data encryption technique
which works simultaneously on multiple network layers.
64/128-bit versus 40/104-bit
The following section explains low-level (64-bit) and high-level (128-
bit) WEP Encryption schemes:
