Subject: NIST Publication Announcements

NIST announces the completion of two NIST Special Publications (SPs): SP
800-56B, Recommendation for Pair-Wise Key Establishment Schemes Using
Integer Factorization Cryptography, and SP 800-102, Recommendation for
Digital Signature Timeliness. Both publications are available at

SP 800-56B provides specifications of key establishment schemes that are
appropriate for use by the U.S. Federal Government, based on a standard
developed by the Accredited Standards Committee (ASC) X9, Inc.: ANS
X9.44, Key Establishment using Integer Factorization Cryptography. A key
establishment scheme can be characterized as either a key agreement
scheme or a key transport scheme. This Recommendation provides
asymmetric-based key agreement and key transport schemes that are based
on the Rivest Shamir Adleman (RSA) algorithm.

SP 800-102 is intended to address the timeliness of the digital
signatures generated using the techniques specified in Federal
Information Processing Standard (FIPS) 186-3. Establishing the time when
a digital signature was generated is often a critical consideration. A
signed message that includes the (purported) signing time provides no
assurance that the private key was used to sign the message at that time
unless the accuracy of the time can be trusted. SP 800-102 provides
methods of obtaining assurance of the time of digital signature
generation using a trusted timestamp authority that is trusted by both
the signatory and the verifier.
