VeriFL

Preface

This repository provides two IntelliJ IDEA projects for VeriFL. The project Client involves the Android benchmark for clients participating in VeriFL protocol. The project Server involves the benchmark of the whole VeriFL protocol (see Server/src/java/com/va/server/Main.java and Server/src/java/com/va/server/SimAggregationServer.java for detail).

Requirements

  • OS: Ubuntu 16.04 LTS
  • IDE: IntelliJ IDEA Community Edition 2019.1.3
  • GCC, G++: version 7.4.0
  • JAVA: 1.8.0_211
  • Cmake: version 3.15.3

To Benchmark VeriFL

To run the VeriFL benchmark program in Server folder, download this repository and run the following commands in shell.

cd Server/src/cpp/build
cmake .. && make
cd ../../..

The parameters required to run the benchmark are listed as follows.

Parameters Description
-logR Set the bit length of the modulus R for the quotient ring Z_R
-d Set the dimension of gradient vectors
-N Set the number of clients
-t Set the threshold of secret sharing
-batch Set the batch size in amortization verification
-maskedColl Set dropouts in the MaskedInputCollection round (e.g., 0,10,2,30 represents there are 10 dropouts in the 0-th epoch and 30 dropouts in the 2-th epoch)
-decom Set the number of clients that drop out in the Decommitting round

For example, in Server/ directory, run

java -Xmx8192m -Xms8192m -Xss8192m -jar Server.jar -logR 24 -d 10000 -N 100 -t 25 -batch 1 -maskedColl 0,0 -decom 0

Note that our simulation requires a large amount of memory and the heap size should be large enough.
