Abstract: Recently, some schemes about verifiable multi-secret sharing based on two-variable one-way function have been proposed. In this paper, we analyse the security of two schemes and draw a conclusion that the both schemes cannot verify whether the dealer is honest or not. We also improve these schemes to make them have the fully verifiable property.

 

Keywords: verifiable MSS; multi-secret sharing; verifiable secret sharing; VMSS; security analysis.
