AES (Advanced Encryption Standard) An encryption algorithm for securing sensitive but unclassified material by U.S. Government agencies and that is being increasingly used for commercial transactions in the private sector. Used in WPA2 security. AP (Access Point) A transceiver or radio component in a wireless LAN that acts as the transfer point between wired and wireless signal, and vice versa.
  • Page 39 networks using the 802.11b specification employ CCK to operate at data speeds of up to 11 Mbps in the radio-frequency band at 2.400 GHz to 2.4835 GHz. Networks using the 802.11g specification employ CCK when operating at 802.11b speeds. At higher speeds (up to a theoretical maximum of 54 Mbps), 802.11g WLANs use a more sophisticated modulation scheme called orthogonal frequency division multiplexing (OFDM).

Encryption changes a data stream of bits from information to something that appears random." Anyone who intercepts the encrypted data gets a data stream that doesn't represent any information.
