Garbled circuit optimization
Webbled circuits but require a particular instantiation of garbled circuits that expands the wire-labels through secret-sharing. We leave it as interesting open work to investigate whether recent optimizations to standard garbled circuits can be sim-ilarly applied to these protocols, and to compare the practi-cal e ciency of malicious-secure variants.

WebJan 8, 2016 · Unlike the optimization techniques of [21, 22, 29, 34], our technique achieves asymptotic reduction of the size of the garbled circuits. Also, unlike the information-theoretic garbled circuit technique of [ 19 ], our technique encodes input in such a way that the size of the encoded input is independent of the depth of the circuit. Webknown as garbled circuits or Yao circuits [52]. A garbled circuit protocol allows two semi-honest parties, a circuit generator and a circuit evaluator, to compute an arbitrary function f(a;b), where a and b are private inputs from each party, without leaking any information about their respective secret inputs beyond what is revealed by the func-
