imagine two people who need to share a secret for example a numeric key. the simplest solution is to make copies of that secret and share it. but what happens when no single person should have full access to a secret,for example missile launch codes or passwords for large money transfers ...
This problem was considered first by A. Shamir [79] and he calls such a scheme a (k, n) threshold scheme.Mignotte, MauriceSpringer, Berlin, HeidelbergM. Mignotte, "How to share a secret?" in Workshop on Cryptography, ser. Lecture Notes in Computer Science, T. Beth, Ed., vol. 149,...
How to share a secret 来自 ACM 喜欢 0 阅读量: 1967 作者: A Shamir 摘要: In this paper we show how to divide data D into n pieces in such a way that D is easily reconstructable from any k pieces, but even complete knowledge of k - 1 pieces reveals absolutely no information about ...
This paper demonstrates that Shamir’s scheme (“How to share a secret”,Communications of the ACM, vol. 22, no. 11, November 1979, 612–613) is not secure against cheating. A small modification to his scheme retains the security and efficiency of the original, is secure against cheating,...
Cite this Share this Abstract Each member of an n-person team has a secret, say a password. The k out of n gruppen secret sharing requires that any group of k members should be able to recover the secrets of the other n − k members, while any group of k − 1 or less member...
Shamir Secret Sharing Scheme. The special algorithm would fragment (break) down the orders, so that darknodes won’t know the destination or amount of crypto that is being transacted REN Token. This token has 2 major functions, as a trading fee and as bond payment. Those who want to use...

TheZengo walletprovides a hybrid solution. Zengo splits the private key into two “shares,” one of which is on your mobile device while the other resides on Zengo’s servers. However, Zengo never has access to your wallet’s private keys because Zengo can’t access the share on your...
(In fact the author received comments on the technical report from Shamir, along with a draft of the threshold scheme.) The essential idea of all three techmques is that someone who knows a secret number can form other numbers from it, such that it is easy to compute the secret number ...
Let S be some secret. A collection of n people Ejshare this secret in such a way that each Ejknows some information xj, for a certain fixed integer k, 2≤k≤n, the knowledge of any k of th x’s enables to find S easily,
