Second Cryptographic Hash Workshop

August 24 - 25, 2006
Santa Barbara, CA

NIST solicits research, surveys, discussion papers, presentations, case studies, panel proposals, and participation from all interested parties, including researchers, system 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. To avoid the possible duplication of papers accepted for this workshop and Crypto 2006, submissions will NOT be considered for this workshop if they are substantially similar to the submissions accepted for Crypto 2006. Topics for submissions should include, but are not limited to, the following:

Mathematical Foundations

  • Iterative structures, i.e., Damgård-Merkle or alternatives;
  • Compression function constructions, e.g. Davies-Meyer;
  • Hashing modes, e.g. randomized hashing or keyed hashing;
  • Formal properties.

Analysis and Design

  • Analysis and design of hash functions and their components;
  • New cryptanalytic techniques against hash functions;
  • Security report on existing hash functions, especially SHA-2;
  • Tools for designing and analyzing compression functions;
  • Provable properties of compression functions, e.g., reductions to hard problems.

Practical Uses and Pitfalls

  • Uses of hash functions in applications and protocols;
  • Properties of hash functions that are assumed, required, or obtained in practice;
  • Vulnerabilities of hash functions caused by unexpected properties or misuse;
  • Desirable properties for future hash functions.

  • Submission Deadline: May 12, 2006
  • Authors Notified: June 23, 2006
  • Workshop Handout Version Deadline: July 21, 2006

Submissions should be provided electronically, in PDF, for standard US letter-size paper (8.5 x 11 inches). Paper submissions must not exceed 15 pages (single space, two column format with 1" margins using a 10 pt or larger font) and have no header or footer text (e.g., no page numbers). Proposals for presentations or panels should be no longer than five pages; panel proposals should include possible panelists and an indication of which panelists have confirmed their participation.

Please submit the following information to

  • Name, affiliation, email, phone, postal address for the primary contact author
  • First name, last name, and affiliation of each co-author
  • The finished paper, presentation, or panel proposal in PDF format as an attachment.

All submissions will be acknowledged.

General information about the workshop including the registration and accommodation information will be available at the workshop website:
