Abstract

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.

Key words: multi-secret sharing, periodic renewing, instant renewing, proactive security

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。
