Paulo S. L. M. Barreto

Paulo S. L. M. Barreto (born 1965) is a Brazilian cryptographer and one of the designers of the Whirlpool hash function and the block ciphers Anubis and KHAZAD, together with Vincent Rijmen. He has also co-authored a number of research works on elliptic curve cryptography and pairing-based cryptography, including the eta pairing technique, identity-based cryptographic protocols, and the family of Barreto-Naehrig (BN) pairing-friendly elliptic curves (together with Michael Naehrig). More recently he has been focussing his research on post-quantum cryptography, being one of the discoverers of quasi-dyadic codes (together with Rafael Misoczki). His paper "Efficient Algorithms for Pairing-Based Cryptosystems", jointly written with Hae Y. Kim, Ben Lynn and Mike Scott and presented at the Crypto 2002 conference, has been identified in March 2005 as a "Hot Paper", and in December 2005 as "Fast Breaking Paper", by Thomson ISI's Essential Science Indicators, by virtue of being among the top one-tenth of one percent (0.1%) most cited papers and by having the largest percentage increase in citations in the Computer Science category.
