NIST announces the release of draft Special Publication 800-106, Randomized Hashing Digital Signatures. This Recommendation provides a technique to randomize the input messages to hash functions prior to the generation of digital signatures to strengthen security of the digital signatures. Please submit comments to quynh.dang@nist.gov with "Comments on Draft 800-106" in the subject line. The comment period closes on September 17, 2007. ******** NIST announces the release of draft Special Publication 800-107, Recommendation for Using Approved Hash Algorithms This Recommendation provides guidance on using the Approved hash algorithms in digital signatures applications, Keyed-hash Message Authentication Codes (HMACs), key derivation functions (KDFs) and random number generators. Please submit comments to quynh.dang@nist.gov with "Comments on Draft 800-107" in the subject line. The comment period closes on September 17, 2007. ****** NIST announces the release of D raft Federal Information Processing Standard (FIPS) 198-1 Publication, The Keyed-Hash Message Authentication Code (HMAC). The draft FIPS 198-1 is the proposed revision of FIPS 198. The draft specifies a keyed-hash message authentication code, a mechanism for message authentication using cryptographic hash functions and shared secret keys. Comments will be accepted through September 10, 2007. Comments should be forwarded to the Computer Security Division, Information Technology Laboratory at NIST or submitted via email to proposed198-1@nist.gov with "Comments on Draft 198-1" in the subject line. Click here to review the Federal Register Notice for Draft FIPS PUB 198-1. ***** NIST announces the release of Draft Federal Information Processing Standard (FIPS) 180-3 Publication, Secure Hash Standard (SHS). The draft FIPS 180-3 is the proposed revision of FIPS 180-2. The draft specifies five secure hash algorithms (SHAs) called SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 which are used to condense input messages to fixed-length messages, called message digests. These algorithms produce 160, 256, 384, and 512-bit message digests, respectively. Comments will be accepted through September 10, 2007. Comments should be forwarded to the Computer Security Division, Information Technology Laboratory at NIST or submitted via email to Proposed180-3@nist.gov with "Comments on Draft 180-3" in the subject line.
