DESCRIPTION:Prof. Joan Daemen\nAbstract: Imagine there’s no block cipher
 s\, it’s easy if you try:-) A (cryptographic) permutation can be thought
  of as a block cipher (like AES or DES) without a key (or with a fixed key
  if you prefer). During the SHA-3 competition it became clear that permuta
 tion-based hashing\, e.g.\, by using the sponge construction\, is superior
  to block-cipher based hashing (as in MD5\, SHA-1 and SHA-2). By including
  a key in the sponge input\, it can readily be used for message authentica
 tion (MAC) and by exploiting the arbitrarily long sponge output even for s
 tream encryption. The duplex variant of sponge widens the spectrum to\, am
 ong other\, authenticated encryption and reseedable pseudorandom generatio
 n and was adopted by a dozen submissions to the CAESAR competition for aut
 henticated ciphers. The disadvantage of the sponge and duplex construction
 s is that they are inherently serial. To address this\, we introduced a fu
 lly parallel counterpart of the sponge\, called Farfalle and propose a bra
 nd new permutation called Xoodoo. Clearly\, there is a lot going on in per
 mutation-based crypto and this talk will get you up to date.
