摘要
云数据存储是未来数据存储的发展方向,但云数据远程存储使用户面临巨大的安全威胁。文章首先研究云存储架构及云数据安全存储问题,其次,分析云数据保护模型,设计云数据完整性校验机制,该机制基于Hash算法,随机化抽取数据块,最后,分析验证该机制系统开销小,置信度高,能够实现云数据完整性校验。
Cloud data storage is the future trend of data storage. However,the remote storage of cloud data makes the user face great security threat. Firstly,the architecture and security issue of cloud storage analyzed,and the design of integrity verification mechanism proposed,and this mechanism,based on hash algorithm,can randomly extract data block. Finally,analysis and evolution indicate that the proposed mechanism is low in cost,high in believability,and can implement integrity verification of cloud data.
