Ibex: Privacy-preserving ad conversion tracking and bidding

This repository contains the codes of the paper "Ibex: Privacy-preserving ad conversion tracking and bidding" in CCS 2022.

Setup

Please refer to install.md.

Code organization

• Private histogram

  • aggregation/aggregation-micro: microbenchmarks of private histogram aggregation protocol.
  • aggregation/throughput: evaluation of throughput of using Ibex's private histogram protocol and non-private method.

• Oblivious bidding

  • bidding/libs: implementation of libraries used in the oblivious bidding protocol. We used and modified the original Microsoft's SealPIR codebase.
  • bidding/microbench: microbenchmarks of oblivious bidding protocol.
  • bidding/end-to-end: evaluation of end-to-end latency of oblivious bidding protocol and non-private method.
