云计算环境中数据安全存储协同模型*

针对云计算环境中来自数据中心或存储区域内部的攻击，以及适应更复杂的存储管理的需求。从分布式体系设计角度提出一个实现存储控制平面和数据存储平面融合的协同体系模型。为协同存储安全模型设计详细的多级可信管理、密钥管理和数据同步方案。实验结果表明对于大量中等文件的读写性能较好，数据安全管理造成的性能损失在可接受范围内。而且具有较好的可扩展性，能够适应大规模分布式存储系统的应用环境。

Data Security Storage Collaborative Model in Cloud Computing

To the attacks from the data center or stroage area in cloud computing environment and meet the requirements of more complex storage management, the collaborative storage model is proposed to merge the stroage control plane and data storage plane from the perspective of distributed architecture. The detailed design schemes of detailed multi-level trusted management, key management and data synchronization are provided for this collaborative model. Experimental results show that the access performance of a large number of medium file is better than benchmark. And the performance loss caused by data security is within acceptable range. The model has good system scalability and can adapt to large-scale distributed storage system application environment.
