Fair and Robust MPC Using a Global Transaction Ledger

Explore a conference talk from Eurocrypt 2016 that delves into Fair and Robust Multi-Party Computation (MPC) using a Global Transaction Ledger. Examine the potential of cryptocurrency technology for cryptographic applications, focusing on Secure Function Evaluation (SFE) with fairness and robustness compensation. Learn about the challenges in SFE with fair compensation and discover a novel approach to SFE with robust compensation. Understand the construction idea behind this approach, which involves compiling a semi-honest SFE protocol and imitating the GMW protocol. Gain insights into the security aspects of SFE with robust compensation and grasp the key takeaways from this innovative research in cryptography.
