摘要:

针对云环境下文件的敏感信息隐藏问题,提出基于属性的可净化签名方案。将可净化的思想引入到基于属性的签名中,有效解决了敏感信息隐藏,保证签名者隐私性的同时提供细粒度访问控制。具体构造了该方案并在CDH假设下证明该方案在标准模型下是不可伪造的。分析表明,与已有方案相比,所提方案适用于云环境下文件的敏感信息隐藏。

Abstract:

Sensitive information in the document needs to be hidden in cloud computing environment, and attribute based sanitizable signature (ABSS) scheme was proposed to solve this problem. The ABSS scheme brings the character of sanitiz-able into ABS in order to hide sensitive information, ensure signer's anonymity and achieve fine-grained access control. Un-der the CDH assumption, the ABSS scheme constructed was proved to be unforged in the standard model. Compared with existing schemes, the proposed ABSS scheme is more appropriate for cloud computing environment.

Key words: attribute based, access control, signature, sanitizable, standard model
