摘要

本文提出一种可信安全的层次式基于身份加密系统T-HIBE

通过层次式分布化的用户私钥产生

以及私钥用户盲因子、用户私钥编号因子和PKG私钥编号因子技术

解决了层次式私钥生成机构的密钥托管和私钥安全传输问题

支持系统高效的用户身份一次认证和可追责性.基于标准的BDH难题假设

文章证明了基本T-HIBE机制和完全T-HIBE机制分别具有IND-sID-OWE和IND-sID-CCA安全性.

Abstract

The paper proposes a trustworthy and secure HIBE (hierarchical identity-based encryption) system named T-HIBE.It generates private keys in a hierarchical and distributed manner.By using the user blinding index

user private key index and PKG private key index

T-HIBE can achieve the trustworthy private key generation and secure private key distribution.Moreover

the T-HIBE system needs one single user authentication whose accountability is traceable.Based on the standard BDH assumption

we prove that the basic T-HIBE and full T-HIBE have the IND-sID-OWE and IND-sID-CCA security respectively.
