| 摘 要： | 为抵抗通常的攻击，用于密码体制的函数应具有高的代数次数. 基于Stinson的秘密共享模型，研究了无条件安全下的欺骗免疫秘密共享. 利用级联满足一定条件的线性函数，构造了代数次数大于2的〖JP9〗k-〖JP〗欺骗免疫秘密共享的定义函数，所给出的函数是关免疫度为k的平衡函数，而且满足〖JP9〗k-〖JP〗强扩散准则.

| Abstract: | Cheating immune secret sharing in the unconditionally secure case was investigated. Secret sharing is a k-cheating immune if any k cheaters are not better off than a participant which follows the protocol honestly. k-cheating immune secret sharing scheme under the unconditionally secure would be given. The obtained function of the secret sharing scheme is k-resilient and satisfies k-strengthened propagation criterion. Furthermore, its degree is high. So it has better cryptographic properties than that of the known results. |
