Security Analysis of a Dynamic Threshold Secret Sharing Scheme Using Linear Subspace Method
Dynamic threshold Linear subspace Forging
2017/11/14
A dealer-free and non-interactive dynamic threshold secret sharing scheme has been proposed by Harn et.al., in 2015. In this scheme, a (t; n) secret sharing scheme in secret reconstruction phase can t...
On the Asymptotic Idealness of the Asmuth-Bloom Threshold Secret Sharing Scheme
secret sharing entropy idealness
2016/1/5
A necessary and sufficient condition for the asymptotic idealness of the AsmuthBloom
threshold secret sharing scheme is proposed. Apart from this, a comprehensive analysis
of the known variants of t...
Efficient Threshold Secret Sharing Schemes Secure against Rushing Cheaters
Secret Sharing Cheating Detection Cheater Identification
2015/12/21
In this paper, we consider three very important issues namely detection,
identification and robustness of k-out-of-n secret sharing schemes against rushing cheaters
who are allowed to submit (possib...

Recently, two novel schemes have been proposed for hierarchical
threshold secret sharing, one based on Birkoff interpolation and
another based on bivariate Lagrange interpolation. In this short pape...

A New (k, n)-Threshold Secret Sharing Scheme and Its Extension
secret sharing scheme threshold scheme threshold ramp scheme
2009/6/9
In Shamir’s (k, n)-threshold secret sharing scheme (threshold
scheme), a heavy computational cost is required to make n shares and
recover the secret. As a solution to this problem, several fast thr...
