Hierarchical Identity-Based Signature with Short Public Keys

摘要：

　　How to construct a high efficient and strong secure hierarchical iden tity-based signature(HIBS) with a low computation cost is the main challenge at present.A new HIBS scheme is proposed in this paper.The new scheme achieves the adaptive(full) security, constant size signatures and short size pub lic keys.In addition, private keys size shrinks as the hierarchy depth increases.The cost of verification only requires four bilinear pairings, which are indepen dent of hierarchy depth.Furthermore, under the CDHI assumption, the scheme is provably secure against existential forgery for adaptive chosen message and identity attack in the standard model.
