A weighted voting protocol that can keep weight secret has been proposed. However, this protocol has a problem that a tallying cost is large when there are many voters, since a management server must re-encrypt and permute all votes. In this paper, we propose a weighted voting protocol with tallying cost reduced.}, title = {集計時の負荷を軽減した重み付き電子投票プロトコル}, year = {2004} }
