Cryptography Private-ID

Overview

Private-ID

Private-ID is a collection of algorithms to match records between two parties, while preserving the privacy of these records. We present two algorithms to do this---one of which does an outer join between parties and another does a inner join and then generates additive shares that can then be input to a Multi Party Compute system like CrypTen. Please refer to our paper for more details.

Build

Private-ID is implemented in Rust to take advantage of the languages security features and to leverage the encryption libraries that we depend on. It should compile with the nightly Rust toolchain.

The following should build and run the unit tests for the building blocks used by the protocols

cargo build, cargo test

Each protocol involves two parties and they have to be run in its own shell environment. We call one party Company and another party Partner.

Private-ID

This protocol maps the email addresses from both parties to a single ID spine, so that same e-mail addresses map to the same key.

To run Company

env RUST_LOG=info cargo run --bin private-id-server -- \
--host 0.0.0.0:10009 \
--input etc/example/email_company.csv \
--stdout \
--tls-dir etc/example/dummy_certs

To run Partner

env RUST_LOG=info cargo run --bin private-id-client -- \
--company localhost:10009 \
--input etc/example/email_partner.csv \
--stdout \
--tls-dir etc/example/dummy_certs

PS3I

This protocol does an inner join based on email addresses as keys and then generates additive share of a feature associated with that email address. The shares are generated in the designated output files as 64 bit numbers

To run Company

env RUST_LOG=info cargo run --bin cross-psi-server -- \
--host 0.0.0.0:10010 \
--input etc/example/input_company.csv \
--output etc/example/output_company.csv \
--no-tls

To run Partner

env RUST_LOG=info cargo run --bin cross-psi-client -- \
--company localhost:10010 \
--input etc/example/input_partner.csv \
--output etc/example/output_partner.csv \
--no-tls

PS3I XOR

This protocol does an inner join based on email addresses as keys and then generates XOR share of a feature associated with that email address. The shares are generated in the designated output files as 64 bit numbers

To run Company

env RUST_LOG=info cargo run --bin cross-psi-xor-server -- \
--host 0.0.0.0:10010 \
--input etc/example/input_company.csv \
--output etc/example/output_company.csv \
--no-tls

To run Partner

env RUST_LOG=info cargo run --bin cross-psi-xor-client -- \
--company localhost:10010 \
--input etc/example/input_partner.csv \
--output etc/example/output_partner.csv \
--no-tls

Private Join and Compute

This is an implementation of Google's Private Join and Compute protocol, that does a inner join based on email addresses and computes a sum of the corresponding feature for the Partner.

env RUST_LOG=info cargo run --bin pjc-client -- \
--company localhost:10011 \
--input etc/example/pjc_partner.csv \
--stdout \
--tls-dir etc/example/dummy_certs

env RUST_LOG=info cargo run --bin pjc-server -- \
--host 0.0.0.0:10011 \
--input etc/example/pjc_company.csv \
--stdout \
--tls-dir etc/example/dummy_certs

SUMID

This is an implmentation of 2-party version of Secure Universal ID protocol. This can work on multiple keys. In the current implementation, the merger party also assumes the role of one data party and the sharer party assumes the role of all the other data parties. The data parties are the .csv files show below

To run merger

env RUST_LOG=info cargo run --bin suid-create-server -- \
        --host 0.0.0.0:10010 \
        --input etc/example/suid/Example1/DataParty2_input.csv \
        --stdout \
        --tls-dir etc/example/dummy_certs

To run merger

env RUST_LOG=info cargo run --bin suid-create-client -- \
     --merger localhost:10010 \
     --input etc/example/suid/Example1/DataParty1_input.csv \
     --input etc/example/suid/Example1/DataParty3_input.csv \
     --stdout \
     --tls-dir etc/example/dummy_certs

The output will be ElGamal encrypted Universal IDs assigned to each entry in the .csv file

Changes to support a wasm32 target (abstract RNG, parallelism, timers)
Types of changes

[x] Bug fix (non-breaking change which fixes an issue)

[x] New feature (non-breaking change which adds functionality)

[ ] Breaking change (fix or feature that would cause existing functionality to change)

[ ] Docs change / refactoring / dependency upgrade

Motivation and Context / Related issue

WebAssembly (wasm32) can now compile directly from the rust code in this repository. And, with the help of the appropriate JavaScript wrappers, the Private-ID algorithm can be run in any web browsers that supports WebAssembly.

Rust rand_core::OsRng is not supported in WebAssembly. An abstracted version is used instead and impliments the trait rand_core::RngCore required by ECCipher.

A web browser can only do multithreading through web workers. Unfortunately Rust's Rayon library doesn't translate to wasm32, so we fall back to ECRistrettoSequential when compiling for the web.

Rust's default timing library fails in the browser, so we conditionally ignore it during compilation. JavaScript can hook the protocol stages and time natively if needed (see private-id-web).

How Has This Been Tested (if it applies)

The original test suite passes without warnings/errors. The new functionality is tested externally at https://github.com/nthparty/private-id-web, because the system-level examples still behave exactly the same, they just happen to compile from code that can now also be compiled to WebAssembly. There are a few new functions to load and dump records to and from JSON formatted strings, but I don't believe these need their own tests beyond the end-to-end tests in the private-id-web repository which depend on them.

Add run_id to PID binaries.

Summary:

Context

For Centralized Logging, we will use a unique run_id to identify a PL/PA run, this run_id will be generated on the partner side and will be consumed by publisher side during instance creation. This run_id will be included in all the multiple ENT instances involved in the run and will also be shared with all the backend components (thrift, PCS, PCA binaries). Design Doc https://docs.google.com/document/d/1vZNOq8GUT1D_7-MjSh2yNpUKVEsvpsYeFx1PjceyelQ/edit?usp=sharing RunID Format RunId will be in UUID format. Ex - 2621fda2-0eca-11ed-861d-0242ac120002

The following test was run locally with and without the newly added option --metric-path and the creation of the output metric file was confirmed.

Add unit tests for calculate_set_diff and set_encrypted_company
Summary:

What

Use automock to mock tests.

Mockall provides tools to create mock versions of almost any trait or struct. They can be used in unit tests as a stand-in for the real object.

The ways to mock

Add #[automock] to the trait

In your test, instantiate the mock struct with its new or default method.

Set expectations on the mock struct. Each expectation can have required argument matchers, a required call count, and a required position in a Sequence. Each expectation must also have a return value.

Supply the mock object to the code that you’re testing. It will return the preprogrammed return values supplied in the previous step. Any accesses contrary to your expectations will cause a panic.

Why

need to improve code coverage
