TKIP - TKIP (Temporal Key Integrity Protocol) is a WEP expanded encryption technique. TKIP has
greatly improved WEP’s weaknesses by rotating secret keys between every packet. TKIP uses
WPA-PSK (pre-Shared Key).
Characteristics:
- The Initialization Vector is expanded from 24-bits to 48-bits.
- The Initialization Vector is randomized.
- Uses a different RC4 key for every packet.
AES - AES further improves TKIP by using AES (Advanced Encryption Standard) encryption
method. Due to its hardware co-processor, AES uses the toughest encryption without sacrifi cing
throughput like WEP and TKIP.
TKIP & AES require an 8 to 63 character passphrase in ASCII or 64 digits hexadecimal key.
Example 1: [ airstation -WPA-PSK ]
Example 2: [0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef]
WPA Group Rekey Interval - When TKIP is selected, the encryption key is renewed at this inter-
val. This interval is in seconds; the range of acceptable values is 0-3600.
If 0 is entered, the key is never renewed.
■ Note: The lower the rekey interval, the more often a rekey occurs. Setting a low rekey interval
may affect performance negatively.
