The latest version of MP-SPDZ adds two protocols with function-dependent protocols. Also in the bag is functionality that helps finding papers and code locations relevant to the computation at hand.

My latest paper investigates the relationship between semi-honest 3PC with replicated secret sharing and similar schemes with function-dependent preprocessing, and I conclude that the additional cost is unlikely to justify the benefits of the latter.

Rep3 denotes the implementation of semi-honest three-party computation with an honest majority in MP-SPDZ (CCS'20). It uses replicated secret sharing with one message per multiplication and party as...

Peer review never sleeps: A student discovered that my code underlying a five-year-old paper uses the wrong curve.

Hi, The curve in P256 element is secp256k1, but the curve for P256 is actually secp256r1 (https://neuromancer.sk/std/nist/P-256) Thank you
