awesome-mpc

The list format was inspired from awesome list and after a fruitful lunch discussion at TPMPC. It is designed to have a central place where everyone can find open-source software designed for MPC as well as introductory material to this topic.

Moreover, the list is given alphabetically and divided into categories of libraries which are actively maintained or recently developed.

Please feel free to do a pull request with any MPC software or resource you know and it is not on the list. The current classification might not be most suitable one and I am open to any suggestions.

Theory

Books

• A Pragmatic Introduction to Secure Multi-Party Computation - A broad introduction to the field of secure multi-party computation, covering both the fundamental constructions and many of the recent improvements. The book emphazises the intuition and ideas behind the protocols rather than rigorous proofs.
• Applications of Secure Multiparty Computation - Collection of MPC protocols for several real-world tasks such as statistics.
• Efficient Secure Two-Party Protocols - Comprehensive study of efficient protocols and techniques for secure two-party computation – both general constructions that can be used to securely compute any functionality, and protocols for specific problems of interest.
• Secure Multiparty Computation and Secret Sharing - Comprehensive treatment of unconditionally secure techniques for multiparty computation (MPC) and secret sharing.

Courses

• Cryptographic Computing Course - Course on MPC, Homomorphic Encryption and related topics given by Claudio Orlandi at Aarhus University.
• FHE-MPC Advanced Grad Course - 'Informal grad course' in FHE and MPC.
• Secure Computation - Secure Computation course offered by Indian Institute of Science covering secret sharing schemes, oblivious transfer to impossiblity results and zero-knowledge proofs.
• Secure Multi-Party Computation at Scale - Boston University course that covers mathematical and algorithmic foundations of MPC, with an additional focus on deployment of state-of-the-art MPC technologies.

Tutorials

• Getting Started with MPC - Light compilation of basic resources for getting started in MPC study and research.
• How To Simulate It - A Tutorial on the Simulation Proof Technique.
• OSU Bibliography - An Annotated Bibliography of Practical Secure Computation.
