M
MAC
Media Access Control address. A unique 48-bit number used in Ethernet data
packets to identify an Ethernet device such as an access point or your client
adapter.
Message Integrity
Code (MIC)
A cryptographic checksum, designed to make it computationally infeasible for
an adversary to alter data. This is usually called a Message Authentication Code,
or MAC, in the literature, but the acronym MAC is already reserved for another
meaning in this standard.
modulation
Any of several techniques for combining user information with a transmitter’s
carrier signal.
multipath
The echoes created as a radio signal bounces off of physical objects.
multicast packet
A single data message (packet) sent to multiple addresses.
O
omni-directional
This typically refers to a primarily circular antenna radiation pattern.
Orthogonal
Frequency Division
Multiplex (OFDM)
A modulation technique used by IEEE 802.11a-compliant wireless LANs for
transmission at 6, 9, 12, 18, 24, 36, 48, and 54 Mbps.
P
packet
A basic message unit for communication across a network. A packet usually includes routing
information, data, and sometimes error detection information.
pairwise
Two entities that is associated with each other; an access point and one associated station, or a pair of
stations in an IBSS network, used to describe the key hierarchies for keys that are shared only between
the two entities in a pairwise.
Pairwise Master Key
(PMK)
The key that is generated on a per-session basis and is used as one of the inputs into the PRF to derive
the Pairwise Transient Keys (PTK). For EAP-TLS authentication, the Pairwise Master Key is the key
from the RADIUS MS-MPPE-Recv-Key attribute. For Pre-Shared Key authentication, the Pairwise
Master Key is the Pre-Shared Key.
PMKID
PMK identification
Pairwise Transient
Key (PTK)
A value that is derived from the PRF using the SNonce and ANonce, and is split up into as many as
five keys (Temporal Encryption Key, two Temporal MIC Keys, EAPOL-Key Encryption Key,
EAPOL-Key MIC Key) for use by the rest of the system.
Pre-Shared Key
(PSK)
A key that is distributed to the units in the system by manual means. Legacy WEP systems without
authentication used Pre-Shared Keys as the WEP keys. The Robust Security Network (RSN)
specification allows a system to use a Pre-Shared Key if there is no other authentication method
available, but using a Pre-Shared Key is not as secure.
