摘　　要：为以低开销实现公有云存储中的数据隐私保护及密钥管理,提出一种基于Logistic混沌序列的公有云存储隐私保护机制。根据云中数据的存储特点,综合使用一维、二维Logistic混沌系统及数据分割技术,通过不同的密钥生成方法,提供不同级别强度的隐私保护。实验结果表明,该方法可以在保护外包数据隐私的同时,有效降低密钥管理难度。To achieve the goal of protecting the privacy and managing keys with low overheads when outsourcing data into the public cloud, a mechanism for the public cloud storage based on Logistic chaotic sequences was proposed. Based on characteristics of outsourcing data, combining the comprehensive use of one-dimensional and two-dimensional Logistic chaotic as well as the data division, different levels of privacy protectionwere provided by adopting different intensities of keys generation methods. The experimental results show that this method can protect the privacy of outsourcing data and reduce the difficulty of keys management at the same time.
