RSA is part of many official standards worldwide. The ISO
(International Standards Organization) 9796 standard lists RSA as a
compatible cryptographic algorithm, as does the Consultative Committee
in International Telegraphy and Telephony (CCITT) X.509 security
standard. RSA is part of the Society for Worldwide Interbank Financial
Telecommunications (SWIFT) standard, the French financial industry's
ETEBAC 5 standard, and the ANSI X9.31 draft standard for the U.S.
banking industry. The Australian key management standard, AS2805.6.5.3,
also specifies RSA.
RSA is found in Internet's proposed PEM (Privacy Enhanced Mail) standard
(see Question 3.8.7) and the PKCS standard for the software
industry (see Question 3.8.9). The OSI Implementors' Workshop
(OIW) has issued implementers' agreements referring to PKCS and PEM, which
each include RSA.
A number of other standards are currently being developed and will be announced over the next couple of years; many are expected to include RSA as either an endorsed or a recommended system for privacy and/or authentication.
