| Abstract(in English) | Using a (k,n)-threshold secret sharing scheme, multiparty protocols allow a group of players to evaluate jointly the output of a function while maintaining the secrecy of privately held inputs. The (k,n)-threshold secret sharing scheme is inefficient from the sense that each share, which is a conveyor of information, cannot be smaller than the original secret. So, the players performing the protocol are imposed to pay the same computation cost as to evaluate the function by non-distributed form, in spite that the function is jointly evaluated by n players. In this paper, we propose an efficient protocol adopting a ramp scheme for the secret sharing, with which each share can be smaller than the original secret. |
