692GLOSSARY

PEAP	Protected Extensible Authentication Protocol. A draft extension to the
	Extensible Authentication Protocol with Transport Layer Security
	(EAP-TLS), developed by Microsoft Corporation, Cisco Systems, and RSA
	Data Security, Inc. TLS is used in PEAP Part 1 to authenticate the server
	only, and thus avoids having to distribute user certificates to every
	client. PEAP Part 2 performs mutual authentication between the EAP
	client and the server. Compare EAP-TLS.
PEM	Privacy-Enhanced Mail. A protocol, defined in RFC 1422 through
	RFC 1424, for transporting digital certificates and certificate signing
	requests over the Internet. PEM format encodes the certificates on the
	basis of an X.509 hierarchy of certificate authorities (CAs). Base64
	encoding is used to convert the certificates to ASCII text, and the
	encoded text is enclosed between BEGIN CERTIFICATE and END
	CERTIFICATE delimiters.

Tree protocol
PIM	Protocol Independent Multicast protocol. A protocol-independent
	multicast routing protocol that supports thousands of groups, a variety
	of multicast applications, and existing Layer 2 subnetwork technologies.
	PIM can be operated in two modes: dense and sparse. In PIM dense
	mode (PIM-DM), packets are flooded on all outgoing interfaces to
	many receivers. PIM sparse mode (PIM-SM) limits data distribution to a
	minimal number of widely distributed routers. PIM-SM packets are sent
	only if they are explicitly requested at a rendezvous point (RP).
PKCS	Public-Key Cryptography Standards. A group of specifications produced
	by RSA Laboratories and secure systems developers, and first published
	in 1991. Among many other features and functions, the standards
	define syntax for digital certificates, certificate signing requests, and key
	transportation.
PKI	Public-key infrastructure. Software that enables users of an insecure
	public network such as the Internet to exchange information securely
	and privately. The PKI uses public-key cryptography (also known as
	asymmetric cryptography) to authenticate the message sender and
	encrypt the message by means of a pair of cryptographic keys, one
	public and one private. A trusted certificate authority (CA) creates both
	keys simultaneously with the same algorithm. A registration authority
	(RA) must verify the certificate authority before a digital certificate is
	issued to a requestor.
