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 http://csrc.nist.gov/publications/PubsSPs.html. 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. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majord...@metzdowd.com
