Abstract

Many modern actively secure multi-party computation protocols make use of a function- and input-independent pre-processing phase. This pre-processing phase is tasked with producing some form of correlated randomness and distributing it to the parties. Whilst the “on-line” phase of such protocols is exceedingly fast, the bottleneck comes in the pre-processing phase. In this paper we examine situations in which the computing parties in the online phase may want to outsource the pre-processing phase to another set of parties, or to a sub-committee. We examine how this can be done, and also describe situations where this may be a benefit.
