基于加密机制的云计算数据可靠存储方案研究

为了克服因收发双方都使用同样钥匙导致的其安全性不高等缺点,引入深度加密机制,与AES(Advanced Encryption Standard)算法耦合,设计了基于双级加密的云计算数据可靠存储方案.先采用AES对用户数据客户端进行对称加密,到达云资源管理器后,采用分布式重组的方法进行深度加密,构造了"初级—深度"双级加密的云计算数据可靠存储结构,并完成了基于加密的云计算数据安全存储加密和解密操作流程.借助Eclipse与Java语言,建立了云计算安全模块.结果表明:该系统的加密效率高,拥有较高的安全性且界面操作简单.

Research on the Secure Storage Scheme of Cloud Computing Based on Encryption Mechanism

In order to overcome the defects such as low security resulting by both using the same key for sending and receiving,the depth encryption mechanism was introduced,and taking it coupling the AES algorithm to propose the secure storage system of cloud computation based on the encryption mechanism. Basing on the analysis of previous research on the security of cloud storage,the symmetric encryption for the user data was used in the client,when the data reached the cloud resource management device,the method of distributed restructuring was used to operate depth encryption; and the security storage structure of "initial encryption-depth encryption"was constructed; and then the encryption and decryption process of data safety storage was finished. Based on the eclipse simulation platform,the design and implementation were done for the cloud computing security module. The results showed that the encryption efficiency and security of this system was high and simple interface.
