WLAN security standards

• IEEE 802.11g standard: 54 Mbits/s on 2.4 Ghz

  • Approved by the working group in February 2003

• IEEE 802.11i standard: security in 802.11* networks

  • Use IEEE 802.1X port access control (April 2001)
  • CCMP (Counter-Mode/CBC-MAC Protocol)
  • TKIP (Temporal Key Integrity Protocol)
    • Dynamic key generation for WEP (Wired Equivalent Privacy)
  • WRAP (Wireless Robust Authenticated Protocol)
  • Key management specific to IEEE and replacement of RC4 by AES
  • Rely on IETF EAP and Radius standards
    • Synchronisation and coherence need time

• Security issues of 802.11b (Wi-Fi) are solved with this new generation

• Security remains a voluntary choice : it must be configured
