| Abstract(in English) | An important issue of secret sharing is to characterize the d-multiplicative schemes. For the perfect schemes, it has been proved that d-multiplicative secret sharing is impossible if some d non-access subsets of players cover the whole set of players. This paper extends this result to the non-perfect schemes. Specifically, we prove that d-multiplicative secret sharing is impossible if some d semi-access and/or non-access subsets cover the whole set of players. Our result indicates no need of relaxing the privacy requirement only for the purpose of realizing d-multiplicative property. |
