| 摘 要： | 在多秘密共享方案中,存在子秘密的生命期较长的问题。为了防止子秘密的泄漏,基于椭圆曲线离散对数问题的难解性,提出一种双重更新的多秘密共享方案,该方案能共享任意多个秘密,能对各子秘密进行定期更新,对处于更新周期内泄漏的子秘密,进行即时更新,双重更新有效提高了系统的安全性。此外,还对系统的实现效率进行了讨论。

| Abstract: | In multi-secret sharing schemes,the shares have a long utilization period.By means of the intractability of ellipse curve discrete logarithm problem,a multi-secret sharing scheme with double renewing is proposed.In the scheme,the shares can be repeatedly used for the reconstruction of multiple secrets,the share of every participant can be renewed periodically,the shares which are betrayed can be renewed instantly.Besides,the efficiency of the scheme is discussed. |
