• 論文抄録 / 内容記述: Rivest Shamir and Tauman have proposed the ring signature scheme which makes it possible to specify a groupwithout revealing which member signed a message.Bresson Stern and Szydlo have showna (k n) threshold ring signature scheme.It is possible to convince a verifierthat at least k members in the n-member group signed a messagewithout revealing which k members signed the message.In this paper we propose a new (k n) threshold ring signature scheme.While the previous schemes form a ring of individual signatures our scheme forms a curve of individual signatures.Our scheme is more efficient than the scheme shown by Bresson et al.Moreover we show thatElGamal's signature scheme which is not based on the trapdoor one-way permutation is available in the threshold ring signature.
