Here are some informations about the experimental results of our paper An improved threshold ring signature scheme based on error correcting codes
Efficient implementation of a CCA2-secure variant of McEliece using generalized Srivastava codes
5 March 2012, by Cayrel, Gerhard Hoffman
This document will outline the details for the source codes of the above
publication. It is our hope that it might help people interested in code-based cryptography to put this subject further by another step.

Implementation of code-based hash-functions and stream-ciphers
20 April 2011, by Cayrel, Matthias Boll and Thorsten Peter
These are the results of a cryptography lab project of Thorsten
Peter and Matthias Boll in winter semester 2010/2011. The lab project contains two main parts: the implementation (C and Java) and performance comparison of several code-based cryptographic schemes.
Implementation of code-based zero-knowledge identification schemes
19 April 2011, by Cayrel, Felix Günther and Holger Rother, Gerhard Hoffman
In the context of the Cryptography Lab in the winter term 2010/2011, our task was to implement three different code-based zero-knowledge identification schemes, namely the ones proposed by Stern in 1993, Véron in 1996, and Cayrel, Véron, and El Yousfi in 2010.

We implemented these three schemes in C and Java.

This article gives a brief overview over the implementation including some timing results; a detailed report of our work as well as the complete source code are attached.
