ABSTRACT:
A mix network with superior privacy and robustness is provided. An apparatus comprising a duplicator and first and second operation modules is disclosed. The first and second operation modules are each comprised of first and second processors. Each processor is comprised of a partial operation device. The duplicator preferably duplicates a vector of encrypted inputs, and provides first and second substantially similar duplicated vectors, to the first and second operation modules, respectively. The partial operation device of the first processor of the first operation module partially operates on the first duplicated vector, then supplies the result to the partial operation device of the second processor of the first operation module which partially operates on it to provide a fully operated on first duplicated vector. Likewise, the partial operation device of the first processor of the second operation module partially operates on the second duplicated vector, then supplies the result to the partial operation device of the second processor of the second operation module which partially operates on the partially operates on the second duplicated vector to provide a fully operated on first duplicated vector. A means for comparing compares the fully operated on first duplicated vector with the fully operated on second duplicated vector.
