*** RIJNDAEL *** Selected by NIST
for the Proposed AES
October 2, 2000
[Note: Apparently, one of our NIST servers was down
for while today, making the webcast inaccessible. It
also has led to a delay in these AES pages being
updated. We will try to make the "archived" webcast
available as soon as possible.]
