Threshold changeable secret sharing schemes revisited

This paper studies the methods for changing thresholds in the absence of secure channels after the setup of threshold secret sharing schemes. First, we construct a perfect (t,n)(t,n) threshold scheme that is threshold changeable to t′>tt′>t, which is optimal with respect to the share size. Thi...
