694GLOSSARY

pre-master secret	A key generated during the handshake process in Transport Layer
	Security (TLS) protocol negotiations and used to derive a master secret.
preshared key	See PSK.
PRF	Pseudorandom function. A function that produces effectively
	unpredictable output. A PRF can use multiple iterations of one or more
	hash algorithms to achieve its output. The Transport Layer Security (TLS)
	protocol defines a specific PRF for deriving keying material.
Privacy-Enhanced	See PEM.
Mail
private 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 private key is provided to only the
	requestor and never shared. The requestor uses the private key to
	decrypt text that has been encrypted with the public key by someone
	else. See also PKI; public key.
PRNG	Pseudorandom number generator. An algorithm of predictable behavior
	that generates a sequence of numbers with little or no discernible
	order, except for broad statistical patterns.
Protected Extensible	See PEAP.

Protocol Independent	See PIM.

PSK	Preshared key. The IEEE 802.11 term for a shared secret, also known as
	a shared key. See shared secret.
