In an identity-based digital signature scheme, private key generator (PKG) knows each user`s signing key, so it can generate a signature which is indistinguishable from the signature generated by the user. This is a serious problem because the property of signature nonrepudiation will not be achieved. In our proposed scheme, it is impossible for PKG to produce a signature which is indistinguishable from any signature produced by a user. Compared with existing signature schemes with batch verification, although our proposed scheme is not the most efficient one, it achieves Girault`s level-3 security, while the others have Girault`s level-1 or level-2 security only. We also formally prove that the proposed scheme is unforgeable and satisfies Girault`s level-3 security based on hard problems. | 關聯: | Mathematical Problems in Engineering, Vol.2014, pp.11 pages | 資料類型: | article | DOI: | https://doi.org/10.1155/2014/854135 |
