密钥分散存储有助于提高密钥的安全性。本文基于Shamir的(t,n)门限密钥共享方案,针对t、n值选取对密钥安全性和易用性的影响关键、微妙和模糊的问题,引入Yager模糊理论第三指标,并结合精确数互补判断矩阵的排序方法建立了对(t'n)门限密钥共享方案中t、n值选取的决策方案优选方法,最后本文通过实例说明了该方法的可行性和有效性。

Decentralized storage for the key can help improving its security.This essay is based on A,Shamir's threshold keysharing scheme,focus on the influence (the key, subtle and vague) on the security and ease of use for t/h ~alue'sselection,added with the third index of the Yager Fuzzy Theory, and combined with the exact value's ',complementary judgment matrix,to build a preferred method for the selected alternatives of the strategic decision scheme in the threshold key sharing scheme The last part of the essay illustrates the feasibility and effectiveness of this method by example.
