See NAT.

whether power to the unit is on or off.
Odyssey
An 802.1X security and access control application for wireless LANs (WLANs), developed by
Funk Software, Inc.
OFDM
Orthogonal frequency division multiplexing. A modulation technique that sends data across
a number of narrow subcarriers within a specied frequency band. The wireless networking
standards IEEE 802.11a and IEEE 802.11g are based on OFDM.
orthogonal frequency division multiplexing

See PMK.
pairwise transient key
See PTK.
PAT
Port address translation. A type of network address translation (NAT) in which each computer
on a LAN is assigned the same IP address, but a different port number. See also NAT.
PEAP
Protected Extensible Authentication Protocol. A draft extension to the Extensible Authentication
Protocol with Transport Layer Security (EAP-TLS), developed by Microsoft Corporation,
Cisco Systems, and RSA Data Security, Inc. TLS is used in PEAP Part 1 to authenticate the
server only, and thus avoids having to distribute user certicates to every client. PEAP Part 2
performs mutual authentication between the EAP client and the server. Compare EAPTLS.
PEM
Privacy-Enhanced Mail. A protocol, dened in RFC 1422 through RFC 1424, for transporting
digital certicates and certicate signing requests over the Internet. PEM format encodes
the certicates on the basis of an X.509 hierarchy of certicate authorities (CAs). Base64
encoding is used to convert the certicates to ASCII text, and the encoded text is enclosed
between BEGIN CERTIFICATE and END CERTIFICATE delimiters.
