3p-circuit-oram-prac-repro/prac

Generating the data for 3P-Circuit ORAM for the PRAC paper

Building the docker

• cd ../docker
• Build the docker image with ./build-docker
• Start the dockers with ./start-docker (This will start three dockers, each running one of the parties.)

Setting the network parameters

• ./set-networking 30ms 100mbit

Generating raw data for the binary search experiments

• cd ../prac

• Run the reproduction script ./repro with one of the following arguments:

  • ./repro test: Run a short (about 30 seconds) "kick-the-tires" test. You should see output like the following:

    Running test experiment...
    Wed Nov  1 03:59:19 PM EDT 2023: Running 16 1 ...
    
    # Test output
    
    CircuitORAMOnln read 16 1 6.289 s
    CircuitORAMOnln read 16 1 355.3125 KiB
    CircuitORAMTotl read 16 1 7.145 s
    CircuitORAMTotl read 16 1 2478.5 KiB  
    
    # End test output
    

  The last four lines are the output data points, telling you that a Circuit ORAM read test on an ORAM of size 2¹⁶, with a network configuration of 1us latency and 100gbit bandwidth, performing 1 read operation, took 6.289 s of online time and 7.145 s of total (precomputation plus online) time, and 355.3125 KiB of online bandwidth and 2478.5 KiB of total bandwidth. If you've run the test before, you will see means and stddevs of all of the output data points. When you run it, the time of course will depend on the particulars of your hardware, but the bandwidths used should be exactly the values quoted above.

  • ./repro all numiters: Run all of the tests, doing numiters iterations of each.

When you're done

Stop the docker:

• ../docker/stop-docker
