FleXOR: Flexible garbling for XOR gates that beats free-XOR

WebJan 8, 2016 · A major line of research on the garbled circuit technique is the reduction of the size of garbled circuits. Since the main efficiency bottleneck of garbled-circuit-based two-party computation protocols is usually network bandwidth, reducing the size of garbled circuits typically leads to a big improvement of efficiency in practice. Footnote 1 WebRecall, row reduction [19] is a technique for \compressing" a standard garbled gate from a size of 4 ciphertexts down to either 3 or 2. Free-XOR is compatible with the milder 3-ciphertext row re-duction (which we call GRR3), but not with the more aggressive 2-ciphertext variant (GRR2). The problem is that gates garbled under GRR2 will have ha ha juice wrld lyrics https://odlin-peftibay.com
