【摘要】：针对保护云存储中用户数据机密性的问题,提出了一种在云服务提供商处加密数据的云存储方案。通过虚拟机隔离技术来构造封闭计算环境,改进RSA公钥加密算法使其不需要重新产生大素数就能实现密钥变化,并通过SSL安全链接传输数据以及密钥,将数据在封闭计算环境中安全加密后再存储至分布式文件系统。封闭计算环境能阻止操作系统中不良应用以及云管理员的攻击,有效防范数据泄露。实验结果表明,用户数据的机密性得到了提升,并且相较于其他在云端加密的云存储方案,所提方案所带来的性能损耗降低了许多。
[Abstract]:To protect the confidentiality of user data in cloud storage, a cloud storage scheme is proposed to encrypt data at cloud service provider.The closed computing environment is constructed by the isolation technology of virtual machine, and the RSA public key encryption algorithm is improved so that it can realize the key change without reproducing the large prime number, and transmit the data and the key through the SSL secure link.The data is encrypted securely in a closed computing environment and then stored in a distributed file system.The closed computing environment can prevent the bad application in the operating system and the attack of the cloud administrator, and prevent the data leakage effectively.The experimental results show that the confidentiality of user data is improved and the performance loss caused by the proposed scheme is much lower than that of other cloud storage schemes encrypted in the cloud.
