一类高效的数据库系统安全存储策略研究

针对云存储环境下多副本方案存储效率低下的问题,设计了一种高效的数据安全存储策略；该策略采用了并行思想,设计了高效的数据同步存储算法;该算法将用户的存储请求同时转发给多个工作者,由这多个工作者同时向每个副本服务器写入数据;该策略将云端设计为整体协调、并行处理模式,即多个工作者由管理者统一分配调度,各个工作者独立地服务于对应的副本存储服务器,由管理者与用户进行交互处理,并且这多个工作者对用户来说是透明的,该设计模式并没有增加用户使用云存储的复杂度;实验结果表明,提出的数据安全存储策略在保证副本冗余的情况下可以有效地降低额外的时间损耗,保证用户读写云端数据的效率不低于单副本情况下的效率;该方案用于云存储环境下高效的数据安全存储是可行的、有效的。

Research on the Strategy of Efficient Data Safety Storage in the Cloud Storage Environment

To solve the problem of the low efficiency of Multi-duplicate under the environment of Cloud Storage, this paper proposed a high-efficiency strategy of data safety storage. The strategy adopts the parallel processing ideology and designed the high-efficiency algorithm of the data parallel storage. The algorithm designed to transponder the request coming from the user to many workers, which write user data to the given duplicate server. The strategy is designed as the integrity coordination and the parallel processing mode, which is to say that all the workers are handled by the manager, and every worker is served to the given duplicate server. The manager handles the mutual actions with the users, and all the workers are transparent to the users. Thus the design mode does not increase the complexity for users to use the cloud storage. The experimental data indicates that the strategy this paper designed can decrease the time spoilage under the condition of Multi-duplicate and can ensure that the efficient of the read and write to the cloud not lower than the single-duplicate. The scheme is used for cloud storage environment and efficient data storage is feasible and effective.
