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).

The ANUBIS Block Cipher	The KHAZAD Block Cipher	The WHIRLPOOL Hash Function	The BKLS/GHS Pairing Algorithm

Software

All software published here is either in the public domain or distributed under the GPL, but notice that some algorithms may be themselves covered by patents.

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.    N.B. You will need to install the MIRACL library for extended precision integer arithmetic.	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
