As a highlight, even a general purpose transport layer protocol, such as SABUL, improves the run-time of 2PC over TCP on EU-Australia connection for circuits with > 10 6 Boolean gates by a factor of 8. ...
Although significantly improved, the performance of 2PC is still prohibitive for practical systems. ...
Though our work only considers Boolean circuits, we note that a framework for mixed protocol was implemented in ABY [17] : this framework combines arithmetic sharing, boolean sharing and garbled circuits ...
