| titleOfInvention | Anonymous signature device, signature verification device, anonymous signature method, anonymous signature program, and signature verification program |
| abstract | An object of the present invention is to increase the variety of signature schemes that can be used for anonymous signatures and also secure the degree of freedom of the number of signature cooperators. In a configuration of a k-out-of-n anonymous signature, A i (sk, r) = A i (A i (sk, r)) as a commitment creation function A i (sk, r) corresponding to at least a part of signature authority. pk, using a function as a r), commitment recovery function V i (pk, s, as c), binary operation a (+) i b and a (-) a i b (a (+) i b) ( -) in the case where an operation that satisfies i b = a, a i ( pk, F i (pk, s) (-) i c) using a reply composition function Z i (sk, r, as c), F I i the inverse permutation function of i in the case where the I i using (sk, c (+) i r). Then, the commitment creation function A i (sk, r), the commitment recovery function V i (pk, s, c), and the answer creation function Z i (sk, r, c) are set according to the signature scheme used by the signature authority. Switch to create and verify the anonymous signature. [Selection diagram] Fig. 1 |
