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.

PEM
.
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.

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

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
