Glossary of CDSA Terms and Acronyms

OID/value pair

An abstract identifer representing a data type and the corresponding value

of that data type.

Optimal Asymmetric Encryption Padding (OAEP)

A method of encoding a message with a masked random number, then

encrypting it.

Open Group

A software standards organization sponsored by major software vendors to

develop and foster industry standards for software interfaces. Open Group

standards include UNIX program interfaces and SQL, a data base query

language.

Pretty Good Privacy (PGP)(TM)

A program used to encrypt and decrypt data using a public key system.

Public Key Cryptography Standards (PKCS)

A set of protocols enabling secure informaiton exchange on the Internet.

PKCS was developed by RSA Labs.

Public Key Infrastructure (PKI)

Protocols, services, and standards used for managing public keys, often

through use of a Certiﬁcate Authority.

RC2

A variable key-size block cipher, with a block size of 64 bits and said to be

2-3 times faster than DES. (Export use of RC2 limits the RC2 key size.) RC2

was developed by RSA Labs.

RC4

A variable key-size stream cipher with byte-oriented operations, whose

algorithm is based on use of a random permutation. RC4 was developed by

RSA Labs.

RSA Public Key Cryptosystem

A popular form of public key cryptography, whose inventors’ surnames

(Rivest, Shamir, and Adleman) form the acronym for a body of algorithms.

SHA-1

A hash function speciﬁed in FIPS 180-1 and typically used with the DSA

signature algorithm.
