- The National Institute of
Standards and Technology (NIST) has been working with industry and the
cryptographic community to develop an Advanced Encryption Standard (AES).
The overall goal is to develop a Federal Information Processing Standard
(FIPS) that specifies an encryption algorithm(s) capable of protecting
sensitive government information well into the next century. The algorithm(s)
is expected to be used by the U.S. Government and, on a voluntary basis,
by the private sector.
Elliptic Curves
- August 1999 - NIST recommends
(but does not require) the following set of Elliptic Curves for Federal
government use. These curves have been generated and reviewed by the government
and include key sizes that are commensurate with the AES and other
FIPS approved cryptographic algorithms. Providing this limited set of
recommended curves will address interoperability and testing concerns.
The Elliptic Curves are provided in Postscript
, PDF and Word
formats. For general information about elliptic curves, you may
refer to ECDSA
(select "Technical Reports" and scan for "The Elliptic Curve Digital Signature
Algorithm (ECDSA)" by D. Johnson and A. Menezes).
Key Management/Exchange
- August 1997 - Electronic
Comments submitted to NIST, regarding NIST's Federal Register announcement
proposing a new FIPS for public-key based cryptographic key management
and exchange.
Digital Signatures
- February 15, 2000 -
NIST announces
FIPS
186-4, Digital Signature Standard (DSS), which supersedes FIPS 186-1.
New items in this FIPS include 1) the approval of Elliptic Curve DSA (ECDSA)
as specified in ANSI X9.62, 2) a list of recommended elliptic curves for
Federal Government use, and 3) an allowance for the continued acquisition
of implementations of PKCS#1 for a transition period of eighteen (18)
months.
- This project was developed
to support emergency access to encrypted data where required to support
federal agencies needs. The most promising mechanisms for such access
require a security management infrastructure. Today, the project is focused
on the development of a public key infratructure (PKI) for the Federal
government. Such an infrastructure can support emergency access to encrypted
data for those agencies that require it, but does not impose additional
requirements on agencies that do not require it.
- The National Institute of
Standards and Technology (NIST) is taking a leadership role in the development
of a Federal Public Key Infrastructure that supports digital signatures
and other public key-enabled security services. NIST is coordinating with
industry and technical groups developing PKI technology to foster interoperability
of PKI products and projects.
DES, Triple DES
- November 17, 1999
- NIST announces
the approval by the Secretary of Commerce of FIPS
46-3, Data Encryption Standard (DES). This revision to the standard
specifies the use of Triple DES, as described in ANSI X9.52. (Comments
were sought on draft FIPS 46-3 earlier in 1999.)
