中文摘要: 作为云存储技术中的突出问题, 安全始终受到用户的关注. 针对云存储安全中的用户身份隐私保护和数据隐私保护设计了一种安全、高效的云存储方案. 在该方案中构建了基于时间序列的多叉树存储结构(MTTS), 并在该结构基础上设计了一种密钥推导算法, 不仅方便了密钥的生成和管理, 并且节省了存储空间. 通过对方案的安全性分析, 结果表明该方案在确保数据存储安全的基础上也能很好地保护用户身份隐私.
Abstract:As the key problem in cloud storage, security is always drawing the users' attention. A safe and efficient cloud storage scheme is designed for users' identity and data privacy protection in cloud storage security. In the scheme, a storage structure based on time series is constructed and designs a key-deriving algorithm based on the structure. It can not only be good for the generation and management of the key but also can save the storage space. By analyzing the security of scheme, it indicates the scheme can insure the security of data and can protect the privacy of users' identity.
