GL
RSN
(Robust Security Network) A secure wireless LAN (WLAN) based on the
developing IEEE 802.11i standard. See also, 802.11i.
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 pre-shared key (PSK), a shared secret is
used as input to a one-way hash algorithm. When a shared secret is used for
authentication and the hash output of both the sender and the receiver match,
they share the same secret and are authenticated. A shared secret can also be
used to generate encryption key. See also, PSK.
SNMP
(Simple Network Management Protocol) A standard protocol that regulates
network management over the Internet. SNMP uses TCP/IP to communicate
with a management platform, and offers a standard set of commands that make
multi-vendor operability possible. SNMP uses a standard set of definitions,
known as a MIB (Management Information Base), which can be supplemented
with enterprise-specific extensions. See also, MIB.
SNTP
(Simple Network Time Protocol) A a simplified version of NTP. SNTP can be
used when the ultimate performance of the full NTP implementation described
in RFC 1305 is not needed or justified. See also, NTP.
spread spectrum
A modulation technique that spreads a signal's power over a wide band of
frequencies. The main reason for the technique is that the signal is much less
susceptible to electrical noise and interferences then other techniques.
SSH
(Secure SHell) A Telnet-like protocol that establishes an encrypted session.
