In July 2000, NIST announced an initial public workshop for the presentation and discussion of block cipher modes of operation. The papers, presentations, and discussions from that workshop are summarized in a workshop report.
NIST received a number of public comments in response to its announcement of the "Modes of Operation" effort.
The table below contains links to the papers and presentations from the first workshop.
