*R100 supports AES and TKIP encryption for WPA.

Utilities .3

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.
