| Abstract(in English) | In 2004, Canetti, Halevi, and Katz proposed a construction of an IND-CCA-secure Public-Key Encryption (PKE) scheme from any IND-ID-CPA-secure Identity-Based Encryption (IBE) scheme. Y. Cui, et al. examined the relationship between IBE and Digital Signatures (DS). However, there does not seem to exist any previous work that has shown the relationship between Identity-Based Signatures (IBS) and DS. In this paper, we propose two constructions of a DS scheme from an Identity-Based Signature scheme. |
