摘要
Share mismatch is detected with a small amount of communication. N inconsistency detection devices generate and publish random numbers si. The n mismatch detection devices generate a shared random number s that is the sum of random numbers s0,..., sn-1. n inconsistency detectors calculate share [c] i. When n inconsistency detection devices are restored, a share [r] i that generates a random number r is generated. When n inconsistency detection devices are restored, the share [d] i that becomes the judgment value d is calculated. One inconsistency detection device receives shares [d] 1,..., [D] n-1 from n-1 inconsistency detection devices. One inconsistency detection device restores n-k shares [d] 'k, ..., [d]' n-1 from k shares [d] 0, ..., [d] k-1. One inconsistency detection device determines whether share [d] j and share [d] ′ j match for j = k,..., N−1. [Selection] Figure 3
