Summary

Protocols for secure multiparty computation enable a set of parties to carry out a joint computation on private inputs, correctly and without revealing anything but the output. Example applications are online auctions, privacy-preserving surveys, and elections. In all these, the outcome depends on the users private inputs, which are supposed to remain secret. Over the last decade, there has been a tremendous effort to make secure multiparty protocols fast enough to be run in practice. Most of the most efficient secure multiparty protocols require many rounds of interaction, and thus their performance drops significantly in high latency networks, such as the internet. In this talk, I will go over some recent advances in concretely efficient constant round secure multiparty protocols based on garbled circuits, which aim to optimize the running time of secure multiparty computation over high latency networks, such as the internet.
