针对海量数据存储安全问题,提出并设计了一种基于智能网络磁盘的安全存储系统。介绍了该存储系统的硬件和软件构成以及体系结构,分别从数据编码、数据分发以及数据恢复3个方面详细阐述了基于纠删码的数据安全存储机制的设计思路,对系统的安全可靠性进行了分析。分析结果表明,提出的安全存储机制具有较高的安全可靠性和良好的整体性能,对系统的时间开销影响较小。
To solve some security issues of massive data storage, a novel storage system based on intelligent network disk (INDMSS for short) is proposed. First, the hardware and software components are introduced, as well as the architecture of INDMSS. Then, to satisfy the requirements of secure data storage, a mechanism based on erasure code is designed, which is elabo- rated from the three aspects of data encoding, data distribution and data recovery in detail. Finally, the security and reliability of the system is analyzed. Experimental results and analysis demonstrate that INDMSS achieves a high reliability and performance and has little influence on system overhead.
