Budoucnost hashovacích funkcí - aktivita NIST

Cryptographic Hash Workshop
NIST Gaithersburg, MD (Green Auditorium)
Oct. 31-Nov. 1, 2005
Submission Deadline: July 15, 2005 (Workshop without Proceedings)

Recently a team of researchers reported that the SHA-1 function offers significantly less collision resistance than could be expected from a cryptographic hash function of its output size. NIST plans to host a Cryptographic Hash Workshop on Oct. 31-Nov. 1, 2005 to solicit public input in how best to respond to the current state of research in this area. The workshop has the following goals:

· Assess the status of the current NIST-approved hash functions, i.e., the SHA-256 and SHA-512 families in addition to SHA-1;
· Discuss short term actions to mitigate the potential problems with the various applications of the approved hash functions;
· Discuss the conditions that would warrant an early transition away from any of the approved hash functions;
· Discuss the potential replacement options for any of the approved hash functions;
· Clarify the properties of unkeyed cryptographic hash functions required for different applications such as digital signatures, key derivation, message authentication, and random number generation.

NIST solicits papers, presentations, case studies, panel proposals, and participation from any interested parties, including researchers, systems architects, vendors, and users. NIST will post the accepted papers and presentations on the workshop web site and include these in a workshop handout. However, no formal workshop proceedings will be published. NIST encourages presentations and reports on preliminary work that participants plan to publish elsewhere. Topics for submissions are included in the attached document, and details about the workshop will be available at the following web site shortly: http://www.nist.gov/hash-function
