| Abstract(in English) | Identity-Based Signature (IBS) provides a public key cryptosystem that a publick key corresponding to user's identity such as an e-mail adress or identifiablity user's data. IBS adopt th way that is a secret key generation ask for one trusted third party called Private Key Generator (PKG). So the key generation costs proportionately increasing user's number. In 2002, Gentry-Silverberg poposed hierarchical Identity-based Signature (HIBS) which is a revisim of PKG as a a tree node. But Gentry-Silverberg's HIBS dosen't construct complete HIBS. The reason is that extra public parameter using in verification. In 2005, Yuen and Wei proposed a HIBS scheme (YW-HIBS) which is provable in the standard security model. This is the first completed hierarchical ID-based signature and which is the most efficient HIBS scheme recent approach. In this paper, we propose improved Hierarchical Identity-Based Signature which is maintain YW-HIBS benefits. |
