摘要:

基于Stinson的秘密共享模型,研究了无条件安全下的严格 -欺骗免疫秘密共享。对任意给定的正整数 ,构造了严格 -欺骗免疫秘密共享,并且秘密共享的定义函数具有任意的代数次数,弹性度为 ,且满足 次强扩散准则。

关键词: 秘密共享;(强)扩散准则, 相关免疫函数, 弹性函数

Abstract:

The work addresses the problem of cheating prevention in secret sharing. For any integer , strictly - cheating immune secret sharing scheme under the unconditionally secure is given. It is concluded that the defining function of strictly secret sharing scheme is -resilient and also is -strengthened propagation criterion. Furthermore, its degree is high. So it has better cryptographic properties than that of the known results.

Key words: secret sharing, (strengthened) propagation criterion, correlation immune functions, resilient functions
