摘要

针对云存储系统和应用过程中的数据安全性问题

提出了一种面向分散式存储的云存储安全架构.该架构采用信息扩散法、分散存储管理、数据自举恢复等技术

分层实现存储数据在云存储中完成应用系统的数据安全存储管理和传输.该方法通过检查可用片重新计算数据片中所有的数据

若存在受损数据

则根据互为冗余的存储设备数据加以恢复

从而提高数据的可用性

从数据传输到存储

都建立了相应的保护措施进行云存储层与其他层间的安全防范

实现了数据的有效防护.仿真测试表明

该架构在保证数据高安全性的同时提高了系统的整体性能.

Abstract

A storage security architecture based on distributed storage is presented to deal with the data security in the cloud storage systems and applications. The mechanism of safety management and transmission of storage data are realized by layer through the use of information dispersal algorithms(IDA)

distributed storage management

and data restore methods. The method improves the high availability of data by examining the usable slices

recalculating all data in data segment

and recovering damaged data according to mutual redundant storage equipment data. Protection measures from the data transmission to storage are taken to ensure safety between cloud storage layer and other layers such that effective data protection is realized. Simulation tests show that the architecture improves the overall performance of the system while ensures the high security of data.
