WebGarbled circuits were famously introduced by Yao in the 1980s [Yao86]. Since that time they have become an invaluable technique for both practical and theoretical cryptographic constructions. Most notably, garbled circuits form the conceptual core for the most practical approaches to secure two-party computation. 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 ...
