WebOct 14, 2024 · The researchers proposed the state-of-art technology of optimizing garbled circuit. Their main idea is to divide the AND gate into two half-gates. c = a ∧ b = a ∧ ( r + r + b) = ( a ∧ r) + ( a ∧ ( r + b)) As far as I can see, it seems that the generator half-gate is enough for an AND gate. based on the input value that the garbler has ...
