门限秘密共享体制的一种防欺诈设计

Design to Identify Cheaters in the Threshold Secret Sharing Scheme

文章给出了一种可以防止在门限秘密共享体制中发生的欺诈行为的方案,并分析了其防欺诈的性能。此方案是通过限制门限体制中的密钥空间而设计的,可操作性强,信息率高,是一个比较实用的秘密共享体制。

This paper proposes a threshold secret sharing scheme to identify cheaters, whose properties are analyzed in detail. The scheme is designed by imposing restriction on the set of secrets in a threshold secret sharing scheme. The scheme is efficient, practical and of higher information rate.
