Public-Key Cryptography Standards
<cryptography, standard> (PKCS) A set of standards for
public-key cryptography, developed by RSA Data Security,
Inc. in cooperation with an informal consortium, originally
including Apple, Microsoft, DEC, Lotus, Sun and
MIT. The PKCS have been cited by the OSI Implementers'
Workshop (OIW) as a method for implementation of OSI
standards.
PKCS includes both algorithm-specific and
algorithm-independent implementation standards. Many
algorithms are supported, including RSA and Diffie-Hellman
key exchange, however, only the latter two are specifically
detailed. PKCS also defines an algorithm-independent syntax
for digital signatures, digital envelopes, and extended
digital certificates; this enables someone implementing any
cryptographic algorithm whatsoever to conform to a standard
syntax, and thus achieve interoperability.

public-key encryption
<cryptography> (PKE, Or "public-key cryptography") An
encryption scheme, introduced by Diffie and Hellman in 1976,
where each person gets a pair of keys, called the public key
and the private key. Each person's public key is published
while the private key is kept secret. Messages are encrypted
using the intended recipient's public key and can only be
decrypted using his private key. This is often used in
conjunction with a digital signature.
The need for sender and receiver to share secret information
(keys) via some secure channel is eliminated: all
communications involve only public keys, and no private key is
ever transmitted or shared.
Public-key encryption can be used for authentication,
confidentiality, integrity and non-repudiation.
RSA encryption is an example of a public-key cryptosystem.

Public Key Infrastructure
<cryptography, communications> (PKI) A system of public key
encryption using digital certificates from Certificate
Authorities and other registration authorities that verify
and authenticate the validity of each party involved in an
electronic transaction.
PKIs are currently evolving and there is no single PKI nor
even a single agreed-upon standard for setting up a PKI.
However, nearly everyone agrees that reliable PKIs are
necessary before electronic commerce can become widespread.
