中文摘要: 在综合分析现有基于密文策略属性加密方案的基础上,针对现有基于密文策略属性加密方案较少考虑属性权重的现状,将权重的概念引入到基于密文策略的属性加密方案中,提出了基于密文策略的权重属性加密方案,证明了在选择权重属性集模型下安全性。并将此方案引入到云计算环境下,给出了系统级的基于密文策略的权重属性加密方案。分析表明,基于密文策略权重属性的加密方案相比现有方案更适用于云计算环境。

Abstract:By analyzing existing ciphertext-policy attribute-based encryption scheme, ciphertext-policy weighted attribute-based encryption scheme was proposed. To solve the existing scheme without considering the attribute with weight, the concept of weight was adopted into ciphertext-policy attribute-based encryption scheme. Meanwhile, the security of ciphertext-policy weighted attribute-based encryption scheme was proved under the selective-weighted attribute model. Moreover, the ciphertext-policy weighted attribute-based encryption scheme was given which has effective application in secure cloud computing environment. Analysis showed that the present scheme is more appropriate for the cloud computing environment than the existing schemes.
