基于封闭环境加密的云存储方案
Cloud storage scheme based on closed-box encryption
摘要
Abstract
Aiming at protecting the confidentiality of data for cloud storage users, a scheme that encrypt data in cloud ser-vice providers was presented. The scheme constructed a closed-box computing environment by virtual machine isolation technique, improved algorithm of RSA to change keys without having to produce large prime numbers, transfer data and keys through SSL and encrypted data in the closed computing environment before storing to the distributed file system. Closed-box computing environment can prevent attacks from cloud administrators and malicious applications in the operat-ing system. It also can guard against data leakage effectively. The result of experiment shows that the confidentiality of data improved and the performance loss is decreased considering to other cloud storage scheme that encrypt data in cloud.关键词
