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

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

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
specication. See also STP.
