GLOSSARY 695

PTK

Pairwise transient key. A value derived from a pairwise master key

 

(PMK) and split into multiple encryption keys and message integrity

 

code (MIC) keys for use by a client and server as temporal session keys

 

for IEEE 802.11i robust security. See also 802.11i.

public key

In cryptography, one of a pair of keys, one public and one private, that

 

are created with the same algorithm for encrypting and decrypting

 

messages and digital signatures. The public key is made publicly

 

available for encryption and decryption. See also PKI; private key.

infrastructure

 

PVST+

Per-VLAN Spanning Tree protocol. A proprietary Cisco protocol that

 

supports a separate instance of the Spanning Tree Protocol (STP) for

 

each virtual LAN (VLAN) in a network and maps the multiple spanning

 

trees to a single tree, to comply with the IEEE 802.1Q specification. See

 

also STP.

QoS

Quality of service. A networking technology that seeks to measure,

 

improve, and guarantee transmission rates, error rates, and other

 

performance characteristics, based on priorities, policies, and reservation

 

criteria arranged in advance. Some protocols allow packets or streams

 

to include QoS requirements.

quality of service

See QoS.

RA

See registration authority (RA).

radio profile

A group of parameters, such as the beacon interval, fragmentation

 

threshold, and security policies, that you configure in common across a

 

set of radios in one or more Managed Access Points (MAPs). A few

 

parameters, such as the radio name and channel number, must be set

 

separately for each radio.
