| Abstract(in English) | A fail-stop signature (FSS) scheme is a digital signature scheme with forgery-proof function, in which even if an adversary succeeds in forging a signature, the signer can construct the proof that forgery has happened. Security requirements of an FSS scheme are divided into two types: one is satisfied against any adversary including an adversary with unlimited computational power, and the other is only satisfied against an adversary with polynomially-bounded computational power. In this paper, the latter type of security requirements are described with consideration of the influence from the former type of security requirements. Then, the relation between verifier's security and unforgeability is considered. |
