I just received my assignment for the Cryptography Lab at TU Darmstadt.

Implementing a re-encryption mix net

In order to offer publicly verifiable vote counting in eVoting the link between voters and their vote has to be broken. In this context mix nets are widely-used to make encrypted votes anonymous. After the mix net performs its operations the correctness of the produced data has to be shown. The goal of this project is to program a re-encryption mix net (consisting of just one node) and the mix net verification method proposed in “Efficient Mix Net Verification by Proofs of Random Blocks” (available on request). The used encryption scheme will be exponential elGamal and the proofs are done using the Schnorr Identification Protocol. Because in eVoting efficiency is also significant a measurement of the performance would be desirable.

I just set up this website to document and publish information about my development projects and publications on which I work during my studies at the department of computer science of the Technische Universität Darmstadt. I will also publish information about the major projects I conduct at my company TMC-Systems GmbH.
