Implementation of a Threshold Paillier Cryptosystem distributed key generation protocol without trusted party described by Takashi Nishide and Kouichi Sakurai in their paper "Distributed Paillier Cryptosystem without Trusted Dealer".
A patch for the Paillier Treshold Encryption Toolbox by UT Dallas is also provided to allow this toolbox to work with our generated keys.
The implementation is still incomplete and wasn't yet properly reviewed. Therefor, it shouldn't be considered as secure or used in some security-critical systems.
Maven is used to manage dependencies and compiling. The following command lines will run the provided local test:
git clone https://github.com/ChristianMct/thresh-pailler-wo-td.git
cd thresh-pailler-wo-td
mvn package
cd target
java -cp classes/:test-classes/:libs/* ProtocolTest
