Tandem HTTP Client Benchmarks

This directory contains benchmarks for the Tandem engine, communicating over HTTP and running from the client's side.

All benchmark groups start their server based on configured handlers, providing the contributor's input for the Tandem engine. The evaluator's input is also provided in the benchmark. Hence, benchmarks are self-contained and can be run with the usual command cargo bench.

All benchmarks were implemented with Criterion.rs.

circuits.rs

This file includes 4 benchmarks with only AND gates and 4 benchmarks with only XOR gates.

Function	Gates
and_10	10 AND
and_100	100 AND
and_1000	1k AND
and_10000	10k AND
xor_10	10 XOR
xor_100	100 XOR
xor_1000	1k XOR
xor_10000	10k XOR

credit_scoring.rs

This file contains a benchmark based on an integration test, simulating a real use case of the Tandem engine. This example takes a credit scoring algorithm as the contributor's input and a user's data and credit history as the evaluator's input. Keeping the algorithm and the user informations private, the Tandem engine calculates the user's credit score.

Function	Gates
credit_scoring_benchmark	24k XOR, 10k NOT, 33k AND

multiplications.rs

This file contains 2 benchmarks, with both AND and XOR gates, generated from simple Garble functions that multiply the contributor's input by the evaluator's input 1 and 10 times.

Function	Gates
mul_1	16k AND, 16k XOR
mul_10	160k AND, 161k XOR
