在哪里可以了解可用于共享加密密钥的方法？ [英] Where can I learn about proven methods for sharing cryptographic keys?

问题描述

假设一个组想要加密一些信息，然后以需要群组一致的方式在组成员之间共享加密密钥来解密信息。我对各种广泛的共识范围从一致到绝对多数的场景感兴趣。一个有用的技术可以应用于对称密钥，私钥或两者。

我可以采取一个裂缝滚动我自己的方法，因为我相信许多SO成员可以。但是出于这个问题的目的，我已经广泛发表并受到专家密码分析师的审查的方法感兴趣。期刊引用是好的，但对学术来源的解释也是非常有用的。

解决方案

我一直被这种秘密共享技术迷住。我已经看到在互联网上实现的代码，但从未见过实际的应用程序。 沙米尔的秘密分享维基百科文章链接到一些实际代码以及原始学术文章。

Suppose that a group wants to encrypt some information, then share the encryption key among the group members in a way that requires the consensus of the group to decrypt the information. I'm interested in a variety of scenarios where the breadth of consensus ranges from unanimity to an absolute majority. A useful technique can apply to symmetric keys, private keys, or both.

I could take a crack at rolling my own method, as I'm sure many SO members could. But for the purposes of this question, I am interested only in methods that have been widely published and have withstood scrutiny by expert cryptanalysts. Journal citations are good, but interpretation of academic sources are very useful too.

解决方案

I have always been fascinated by this secret sharing technique. I've seen code implementing it on the internet, but have never seen actual applications. Shamir's secret sharing The wikipedia article links to some actual code, as well as the original academic article.
