          <dc:description>重み付き投票とは，株主総会における議決権行使に代表されるように，１人が複数票を投票可能な投票である．従来，重み情報を秘匿できる重み付き電子投票プロトコルが提案されている．しかし，このプロトコルでは集計の際に各投票の最暗号化とランダムな置換を行わなければならないため，投票者数が多い場合，集計に時間を要する．そこで本稿では，集計時の負荷を軽減した重み付き電子投票プロトコルを提案する．</dc:description>
          <dc:description>A weighted voting is a system such that a voter submits a vote with a weight, e.g., voting in stockholders' meetings. 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.</dc:description>
