seed (1) An input to a pseudorandom number generator (PRNG), that is
generally the combination of two or more inputs. (2) The Wireless
Switch (WX) that distributes information to all the WX switches in a
Mobility Domain™ group.
SentrySweep™ A radio frequency (RF) detection sweep that runs continuously on the
disabled radios in a Mobility Domain™ group. See also RF detection
session A related set of communication transactions between an authenticated
user (client) and the specific station to which the client is bound.
service set identifier See SSID.
SHA Secure hashing algorithm. A one-way hashing algorithm used in many
authentication algorithms and also for key derivation in many
algorithms. A SHA produces a 160-bit hash.
shared secret A static key distributed by an out-of-band mechanism to both the
sender and receiver. Also known as a shared key or preshared key
(PSK), a shared secret is used as input to a one-way hash algorithm.
When a shared secret is used for authentication, if the hash output of
both sender and receiver is the same, they share the same secret and
are authenticated. A shared secret can also be used for encryption key
generation and key derivation.
SIP Session Initialization Protocol. A signaling protocol that establishes
real-time calls and conferences over IP networks.
SSH Secure Shell protocol. A Telnet-like protocol that establishes an
SSID Service set identifier. The unique name shared among all computers
and other devices in a wireless LAN (WLAN).
