This document uses the following terms:
access point: A network access server (NAS) that is implementing [IEEE802.11-2012], connecting wireless devices to form a wireless network.
ad hoc network: A self-configuring wireless network of mobile routers (and associated hosts) that are connected by wireless links, the union of which form an arbitrary topology. See [IEEE802.11-2007].
Authentication Protocol (AP) exchange: The Kerberos subprotocol called the "authentication protocol", sometimes referred to as the "Client/Server Authentication Exchange", in which the client presents a service ticket and an authenticator to a service to establish an authenticated communication session with the service (see [RFC4120] section 3.2).
basic service set (BSS): A collection of devices controlled by a single coordination function that joined a common IEEE 802.11 wireless network, as defined in [IEEE802.11-2007] section 3.7.
hash: A term that refers to either a hash function, the value computed by such a function, or the act of computing such a value.
Hash-based Message Authentication Code (HMAC): A mechanism for message authentication using cryptographic hash functions. HMAC can be used with any iterative cryptographic hash function (for example, MD5 and SHA-1) in combination with a secret shared key. The cryptographic strength of HMAC depends on the properties of the underlying hash function.
independent basic service set (IBSS): A basic service set (BSS) that is an autonomous network, as defined in [IEEE802.11-2007]. An IBSS does not provide access to a distribution system.
information element (IE): A unit of information transmitted as part of the management frames in the IEEE 802.11 [IEEE802.11-2012] protocol. Wireless devices, such as access points, communicate descriptive information about themselves in the form of one or more IEs in their management frames.
keyed-hash Message Authentication Code: A symmetric keyed hashing algorithm used to verify the integrity of data to help ensure it has not been modified while in storage or transit.
Medium Access Control (MAC) protocol data unit (MPDU): The unit of data exchanged between two peer MAC entities using the services of the physical layer.
Message Authentication Code (MAC): A message authenticator computed through the use of a symmetric key. A MAC algorithm accepts a secret key and a data buffer, and outputs a MAC. The data and MAC can then be sent to another party, which can verify the integrity and authenticity of the data by using the same secret key and the same MAC algorithm.
Message Authentication Code sublayer management entity (MLME): An entity that provides the layer management service interfaces through which layer management functions can be invoked.
namespace: An abstract container that provides context for the items (names, technical terms, or words) that it holds and allows disambiguation of items that have the same name (residing in different namespaces).
octet: A group of 8 bits often referred to as a byte.
organizationally unique identifier (OUI): A unique 24-bit string that uniquely identifies a vendor, manufacturer, or organization on a worldwide l basis, as specified in [IEEE-OUI]. The OUI is used to help distinguish both physical devices and software, such as a network protocol, that belong to one entity from those that belong to another.
service access point (SAP): An identifying label for network endpoints that are used in Open Systems Interconnection (OSI) networking. The SAP is a conceptual location at which one OSI layer can request the services of another OSI layer.
station: Any device that implements LLTD.
station (STA): Any device that contains an IEEE 802.11 conformant medium access control and physical layer (PHY) interface to the wireless medium (WM).
station management entity (SME): In general, a station management entity (SME) is regarded as responsible for functions such as the gathering of layer-dependent status from the various layer management entities and setting the value of layer-specific parameters. An SME would typically perform such functions on behalf of general system management entities and would implement standard management protocols.
Unicode: A character encoding standard developed by the Unicode Consortium that represents almost all of the written languages of the world. The Unicode standard [UNICODE5.0.0/2007] provides three forms (UTF-8, UTF-16, and UTF-32) and seven schemes (UTF-8, UTF-16, UTF-16 BE, UTF-16 LE, UTF-32, UTF-32 LE, and UTF-32 BE).
Uniform Resource Identifier (URI): A string that identifies a resource. The URI is an addressing mechanism defined in Internet Engineering Task Force (IETF) Uniform Resource Identifier (URI): Generic Syntax [RFC3986].
MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
