Garbled circuit是什么

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.
