| 摘 要： | 在动态安全的多秘密共享方案中,存在更新周期难以确定的问题。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。双重更新不仅有效提高了系统的安全性,而且能方便更新周期的选取。

| Abstract: | In proactive secure multi-secret sharing schemes,it is difficult to determine the renewal period.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.The scheme has the advantage of high security.The renewal period is selected conveniently in the scheme. |

| Keywords: | multi-secret sharing periodic renewing instant renewing proactive security |
