NIST - výb?r nového módu pro blokové šifry
15.04.2005As part of NIST's ongoing effort to update and develop modes of operation for use with the AES algorithm, NIST intends to recommend either the Galois Counter Mode (GCM) or the Carter-Wegman + Counter (CWC) mode. GCM and CWC are modes for authenticated encryption with associated data, combining Counter mode confidentiality with authentication that is based on a universal hash algorithm. Both GCM and CWC are parallelizable, and as far as NIST is aware, neither GCM nor CWC is encumbered by intellectual property. The submission documents specifying GCM and CWC are available through the modes home page. NIST invites comments on these two modes by June 1, 2005.
