Transputation Framework

Transputation allows secure computation researchers to focus on the protocol details without worrying about the networking aspects of the implementation.

This code is provided as an experimental implementation. We cannot guarantee security or correctness

Getting Started

Compiling

Compilation of the is straight forward.

cd transputation
make

Installing

Simply run (as root)

make install

Using the Framework

Transputation is written in C++ and must be used with a C++ compiler.

Minimal working example client:

#include <stdio.h>
#include <transputation/transputation.h>

using namespace transputation;

int main(int argc, char *argv[]) {
  uint8_t data[256];

  for (uint16_t i = 0; i < 256; i++) {
    data[i] = i;
  }

  Packet *packet = new Packet(256, data);
  Transport *t = Transport::GetTransport("TCP");

  t->SetupClient("127.0.0.1", 1234);
  t->Connect();
  t->Send(packet);
  t->Close();
}

Compile with c++ -o client client.cc -ltransputation -lpthread

Minimal working example server:

#include <stdio.h>
#include <transputation/transputation.h>

using namespace transputation;

int main(int argc, char *argv[]) {
  uint8_t data[256];

  for (uint16_t i = 0; i < 256; i++) {
    data[i] = i;
  }

  Packet *expected = new Packet(256, data);
  Transport *t = Transport::GetTransport("TCP");

  t->SetupServer("0.0.0.0", 1234);
  t->Accept();
  Packet *packet = t->Recv();

  if (packet->Equals(expected)) {
    printf("Packets match.\n");
  } else {
    printf("Packets differ.\n");
  }

  t->Close();

Compile with c++ -o server server.cc -ltransputation -lpthread

Example uses

We made an experimental fork of libscapi using the transputation framework. It can be found at https://github.com/Fraunhofer-SIT/transputation_libscapi
