Security Analysis of a Dynamic Threshold Secret Sharing Scheme Using Linear Subspace Method
Sadegh Jamshidpour and Zahra Ahmadian
Abstract
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 turn into a (m; n) scheme in secret reconstruction phase, where m is the number of participanting shareholders. It has been claimed that the secrecy of shares and the secrecy of the secret are unconditionally preserved if
