| 摘 要： | 有向门限群签名方案可以在同一个签名过程内完成有向签名和门限群签名,代价远小于对签名进行加密或进行交互式验证。提出了一种基于椭圆曲线的有向门限群签名方案,结合了改进的ECDSA方案、门限群签名思想和可验证秘密分享方案,只有指定接受者可以验证签名。并对方案的正确性和安全性进行了分析,指出该方案比基于大数分解和离散对数问题的门限群签名方案更安全更实用。

| Abstract: | Directed threshold signature scheme can complete directed signature and threshold signature in one process of signature,while its cost is smaller than encrypting the signature or interactive verification.In this paper,a directed threshold signature scheme based on elliptic curve is proposed,which integrated an improved ECDSA scheme,threshold signature and a verifiable threshold signature scheme,only specific receiver can verify the truth of signature.The truth and security of the scheme is analyzed and discussed. |
