A(t,n)threshold secret sharing scheme is the scheme which allows a trusted party to distribute the shares among n participants in such a way that any t of them can recover the original secret, but any group knowing only t-1 or fewer sharescan not. Recently, Eslami et al. and Tadayon et al. proposed threshold multi-secret sharing schemes, respectively. They proposedthat their schemes don’t require secure channels. But, without secure channels in their schemes, everyone can get the shares andfind the secrets. The proposed scheme does not use secure channels and only t participants can solve the equations of thesystem from the delivered share shadows and find the secrets.
