摘要： 在椭圆曲线可验证门限签名的基础上，结合Feldman可验证秘密共享和一种新型的可验证密钥重分派算法，提出一种具有前摄安全性、参数可调节的椭圆曲线可验证门限签名方案。该方案通过周期地在不同的访问结构中重新分派密钥分片，增强了签名密钥的安全性，同时使签名方案中的门限和签名服务器个数都可动态调整，增强了灵活性和可伸缩性。

Abstract: A proactive secure and adjustable threshold signature scheme for Ad Hoc network is proposed based on the verifiable threshold elliptic curve digital signature algorithm, using the Feldman verifiable secret sharing scheme and a new verifiable secret redistribution scheme. In the proposed scheme, security is enhanced through the periodically redistributed secret shares. Furthermore, the threshold and the number of servers can be adjusted easily.
