Alpha-ESF

Feature

This is an implementation of an efficient private identity verification method $\alpha$-ESF, where the server-side dataset can amount to billion scale. In the processing of PIV, the client can learn the PIV result, while the server should not learn any additional information. We also provide an example on synthetic dataset below.

Environment

• Ubuntu 18.04
• g++ 9.4.0
• cmake 3.24.0

Required Libraries

• NTL 11.5.1
• GMP 6.2.1
• Boost 1.77.0
• CryptoTools
• Henc

Compilation

mkdir build && cd build
cmake ..
make
cd ..

Test

• Bucket-ESF index construction

  mkdir index
  ./main --build --path data/psi_200.txt --Ns 200 --B 10 

• Start up server

  ./main --r 0 --endpoint localhost:1212 --Ns 200 --Nc 100 --Alpha 10 --B 10

• Start up client

  ./main --r 1 --path data/psi_100.txt --endpoint localhost:1212 --Ns 200 --Nc 100 --Alpha 10 --B 10

• For more information, you can use --help flag

  ./main --help
