云计算下数据安全存储技术研究

摘要
云计算技术的发展,极大地提高了计算和存储资源的利用率,用户对数据的使用也变得更便利。但是,云计算环境下的开放性也让用户数据安全性面临较大挑战,成为当前阻碍云计算技术发展的主要问题之一。针对当前云计算环境下用户数据存储安全的需求,提出一种云计算环境下数据安全存储方案,基于有限域GF(2)上的随机矩阵,构造相应的编译码算法,以进行数据的编译码存储,同时通过动态调整数据文件编码数据量,实现对用户存储成本和数据安全可靠性的优化控制。
The development of cloud computing greatly raises the utilization of computing and storage resources, and the users' access to data also becomes more convenient. However, the openness of cloud computing environments also make user data security face greater challenges, and this now becomes one of the main problems hindering the development of cloud computing technology. Aiming at the requirement of user data storage security in cloud computing environment, a data security storage scheme is proposed.Based on the random matrices in infinite field GF(2), the corresponding coding and decoding algorithms are constructed, so as to realize the data storage. Meanwhile, by dynamically adjusting the number of coding blocks, the optimal control on user storage cost and data security is realized.
