stadium's Issues

Change deployment of cluster to receive config instructions from Coordinator and report back round results to Coordinator

Config instructions like: message number, message size, number of servers, chain length

Allows multiply rounds testing different things to be strung together with a Coordinator config file.

Message entry and de-duplication scheme

Forward secrecy

Consider adding forward secrecy to onion encryption via ephemeral keys (e.g., using x25519).

This might not be important depending on how often servers rotate their keys.

Message content should be hybrid encrypted.

Add GPU support to Groth shuffle

Sending message content along with mailbox ids

-Message content is stored in separate message batch that is not verifiably monitored
-Message content batch is hybrid encrypted (symmetrically encrypted with symmetric key encrypted with public key of next server)

Add support to shuffle interface to return permutation right away and do shuffle in background

Returning the permutation immediately allows messages to be passed to the next server. Servers will more effectively utilize their cores generating all shuffle proofs for a mixing round at once.

Distribution verification

-Currently requests paths from senders to self-verify batch that it received

TODO
-Verify random server batches
-Verify merkle paths of sender merkle trees to make received messages are honest
-Verify merkle paths of receiver merkle trees to show senders messages were incorporated

Problem replicating benchmark - signal SIGFPE: floating-point exception

Hello,

I'm trying to replicate your studyresults on my own thesis and I came across this problem.

First some background, I'm running this on the cloud of a german provider (Hetzner) and to run it on Ubuntu 16.04 I've executed the following steps:

    apt-get update;
    apt-get install git make g++ libssl-dev libgmp3-dev libboost-all-dev libtool libtool-bin;
    wget http://www.shoup.net/ntl/ntl-9.8.1.tar.gz;
    gunzip ntl-9.8.1.tar.gz;
    tar xf ntl-9.8.1.tar;
    cd ntl-9.8.1/src;
    ./configure NTL_THREADS=on NTL_GMP_LIP=on NTL_THREAD_BOOST=on SHARED=on;
    make;
    make install;
    export LD_LIBRARY_PATH=/usr/local/lib/:\$LD_LIBRARY_PATH;
    cd /tmp;
    wget https://dl.google.com/go/go1.15.1.linux-amd64.tar.gz;
    tar -xvf go1.15.1.linux-amd64.tar.gz;
    mv go /usr/local;
    export PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/go/bin:$HOME/go/bin;
    export GOPATH=$HOME/go;
    mkdir -p $GOPATH/src;
    cd $GOPATH/src;
    git clone https://github.com/nirvantyagi/stadium.git;
    cd stadium/groth;
    make clean; make lib;
    export LD_LIBRARY_PATH=/usr/local/lib/:$HOME/go/src/stadium/groth;
    cd stadium/groth/;
    chmod +x libshuffle.so;
    sudo cp libshuffle.so /usr/local/lib/;
    export CGO_CXXFLAGS_ALLOW=".*"; 
    export CGO_LDFLAGS_ALLOW=".*";
    export CGO_CFLAGS_ALLOW=".*";
    go get stadium/groth stadium/stadium stadium/coordinator stadium/server;
    go install stadium/groth stadium/stadium stadium/coordinator stadium/server;

Running make test and ./test goes without error but as soon as I try the 3-server example I run into this:

server -conf config/three-server.conf -id 1
