Beyond Honest Majority: The Round Complexity of Fair and Robust Multi-party Computation
Fairness and Guaranteed Output Delivery MPC Round Complexity
2019/9/5
Two of the most sought-after properties of Multi-party Computation (MPC) protocols are fairness and guaranteed output delivery (GOD), the latter also referred to as robustness. Achieving both, however...

2019/6/26
Classification of personal text messages has many useful applications in surveillance, e-commerce, and mental health care, to name a few. Giving applications access to personal texts can easily lead t...
Improved Building Blocks for Secure Multi-Party Computation based on Secret Sharing with Honest Majority
cryptographic protocols secret sharing
2019/6/19
Secure multi-party computation permits evaluation of any desired functionality on private data without disclosing the data to the participants and is gaining its popularity due to increasing collectio...
MPCircuits: Optimized Circuit Generation for Secure Multi-Party Computation
Multi-party computation secure function evaluation logic synthesis
2019/3/13
Secure Multi-party Computation (MPC) is one of the most influential achievements of modern cryptography: it allows evaluation of an arbitrary function on private inputs from multiple parties without r...
