Security Architecture Client Authentication and Encryption

Cisco Wireless Security Suite supporting WPA includes:

  • Authentication
  • Provides 802.1X support, including Cisco LEAP, EAP-Flexible Authentication via Secure Tunneling (EAP-FAST), Protected EAP-Generic Token Card (PEAP-GTC), PEAP-Microsoft Challenge Authentication Protocol Version 2 (PEAP-MSCHAP), EAP-Transport Layer Security (EAP-TLS), EAP-Tunneled TLS (EAP-TTLS), and EAP-Subscriber Identity Module (EAP-SIM) to yield mutual authentication and dynamic, per-user, per-session encryption keys (WPA).
  • Provides MAC address and standard 802.11 authentication mechanisms.
  • Encryption
  • TKIP encryption enhancement: 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.
