WebNov 13, 2024 · Garbled Circuit (GC) is the main practical 2PC technique, yet despite great interest in its performance, GC notoriously resists improvement. Essentially, we only know how to evaluate GC functions gate-by-gate using encrypted truth tables; given input labels, the GC evaluator decrypts the corresponding output label. WebJun 8, 2024 · It is important to realize that a garbled circuit differs from a regular Boolean circuit. In a Boolean circuit, semantic and syntax are basically the same: we are assigning to each wire two possible semantic values, namely True or False, which we will syntactically denote as a signal with 1 or 0 values respectively.
