| Abstract(in English) | The measures against compromise of signing ability are becoming important with the rise of the demand for the digital signature technology. As measures against the exposure of the signing key which is one of the cases of the compromise of signing ability, several signature schemes such as Forward-Secure Digital Signature and Hysteresis signature were proposed. However, even if the legitimate signer uses those measures, without a discovery of the forged signature or the inquiry from the verification process he cannot notice the fact that his signing key has been exposed. Therefore, a safety measure after the exposure of signing key would be delayed, which may lead to a more serious damage. In this paper, to reduce the damage after the exposure of signing key, we propose a digital signature scheme that can detect the compromise of signing ability at the early stage. By using this scheme, we can reduce the damage caused by exposure of signing key. |
