Threshold Elliptic Curve Digital Signature Algorithm (Threshold ECDA)
, 2007 橢圓曲線數位簽章演算法 (ECDSA) 是被廣為應用的簽章標準。我們推演出了門檻式的橢圓曲線數位簽章演算法。在我們提出的機制中，原本的 ECDSA 簽署者被分散成 n 個成員的群體。在 t<n/2 的前提下，該群體以秘密分享的方式共享某個橢圓曲線私密金鑰。 簽署一個合法的簽章需要群體中至少 t 個成員，任何少於 t 的共謀將無法偽造簽章也無法獲得其他成員的部分私密金鑰。 即使在某些成員企圖破壞運算過程的情況下，其他的成員可藉著互動式零知識驗證的技巧辨識出欺騙者。我們的機制混合了可驗證秘密分享 ...
