Abstract(in English)	Publicly verifiable secret sharing(PVSS) allows everybody, not only the participants, to verify that the shares are correctly distributed. Former PVSS is based on public-key encryption. So the security of secret is computational. In this paper we introduce new notion "locally PVSS" which meets weak condition of PVSS. We use trusted authority called "trusted initializer" that exists only in the initialization protocol of the scheme and propose locally PVSS based on unconditional security.
