Tools for creating some shares and commitments for computation

How to build

cmake . -B build
cd build
make -j

Prerequisite before running

• Move the generators.txt into the build directory.
• Move adv-gen-sc.sh and adv-gen-sc-interactive.sh into the build directory.

Generate local verification materials for verification

• Run bash adv-gen-sc.sh BIDDER-NUM BUCKET-NUM DIR-TO-STORE-SHARES DIR-TO-STORE-COMMITMENTS from build directory.
  • The script also generates three files, each containing all file names of share1, share2 and commitments, with a prefix $ADV_NUM-$BUCKET_NUM-.
  • DIR-TO-STORE-SHARES is the directory where the generated shares are stored and DIR-TO-STORE-COMMITMENTS is the directory where the generated commitments are stored.
  • To generate materials of non-interactive, 2-round-interactive, 4-round-interactive variants, set BUCKET-NUM to 10000, 100, and 10 respectively.

Generate materials for throughput evaluation

• Run bash adv-gen-sc-interactive.sh $BIDDER-NUM $BUCKET $SHARE_DIR $COMMIT_DIR $round to generate shares and commitments locally.
  • BUCKET-NUM should be set to 100 and 10 for interactive protocol of 2-round and 4-round respectively. BUCKET-NUM here refers to the number of buckets the servers use to compute in each round of interactive protocol.
  • SHARE_DIR is the directory where the generated shares are stored and COMMIT_DIR is the directory where the generated commitments are stored.
  • The script creates a directory ${ROUND}-interactive-id, where there are 3*ROUND files, each containing all file names of share1, share2 and commitments materials for r round, $r-round-s1-idx, $r-round-s2-idx, and $r-round-commit-idx.

Generate materials for local computation costs of interactive variants

Follow the instruction of Generate materials for throughput evaluation.

Generate materials for local computation costs of non-interactive protocol

Follow the instruction of Generate local verification materials for verification, but only need to set BUCKET-NUM to 10000.
