3.3.3 What was the schedule for the AES?

RSA Labs' FAQ 4.1

(Revised January 2003)

It would have been surprising if the process for choosing something as important as a block cipher standard for the next 20-30 years (which is the intended lifetime of the AES) were not long and involved. June 15, 1998 was the last day to submit an algorithm. Following that, there was a period of review before five candidates (see the previous question) were chosen for further, more involved scrutiny. From these five, the winner, Rijndael, was chosen in October 2000. FIPS PUB 197, which specifies the standard, was published in November 2001.
