Security

CISCO Wireless Security Suite supporting WPA and WPA2, including:
Authentication:
802.1X support, including CISCO LEAP, EAP-FAST, PEAP-GTC, PEAP-MSCHAPv2), and EAP-TLS to yield mutual authentication and dynamic per-user, per-session encryption keys (WPA and WPA2)
MAC address and standard 802.11 authentication mechanisms
Encryption:
AES-Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP) encryption (WPA2)
TKIP encryption enhancements: key hashing (per-packet keying), message integrity check (MIC), and broadcast key rotation via CISCO TKIP or WPA TKIP
Support for static and dynamic IEEE 802.11 WEP keys of 40 and 128 bits
