RondoMPC: Asynchronous MPC with G.O.D. made More Practical (opens in new tab)

Asynchronous multi-party computation (AMPC) en- ables a set of mutually distrustful parties to securely compute any joint function on their private inputs under arbitrary network delays. The guaranteed output delivery (i.e., G.O.D.) property is essential for availability, but can be very challenging to achieve in practice. HoneyBadgerMPC (CCS 2019), the first practical AMPC protocol, follows Beaver’s paradigm that generates Beaver triples offline to simplify online computation. One of the und...
