My (now very outdated) list of research publications, including preprints, reports, manuscripts, talks, Ph.D. thesis, as well as distinctions, activities in program committees of conferences, and the list of my co-authors. For more up-to-date information, I recommend my Lattes or ResearcherID pages.

Algorithms

Some cryptographic algorithms I colaborated to design. Follow the links to get specifications, test vectors and reference implementations (see also the software section below).

Software

All software published here is either in the public domain or distributed under the GPL.

Software	Language
The ηT approach to the Tate pairing, and supporting (supersingular) elliptic curve arithmetic in characteristic 3 (plus very experimental code in characteristic 2). This implementation is distributed under the GPL. You will need to install the MIRACL library for extended precision integer arithmetic. BEWARE: this software is for research purposes only, NOT for actual deployment!	C++
The AES block cipher, the GCM and EAX authenticated encryption with associated data modes of operation, and the CMAC (originally OMAC) message authentication code, in C++ and Java.	C++, Java
The Aspiring Cryptanalyst's Toolkit (ACTK), old version.	C
The Skipjack block cipher.	C
The SQUARE block cipher.	C, Java
Elliptix Lite (elliptic curve cryptography), old version.	Java
