Carter 2 IEEE 802.11 Security • No key distribution specified • Supports one way authentication – Open – Shared key • Supports Encryption – 40 bit key length – Uses RC4 for Pseudo-Random Numbers – Station-to-station, not end-to-end 13 Nov 2000 Iowa State University CprE 537X James W. Carter 3 IEEE 802.11 Authentication Requesting Station Authenticating Station Authentication Frame Challenge Text Encrypted Challenge Text Authentication Frame Success or Failure Use WEP and Secret Key 13 Nov 2000 Iowa State University CprE 537X James W.
