摘要

针对云存储系统中的数据安全问题，提出了一种面向云存储安全的可自愈拜占庭Quorum系统.该系统以虚拟机作为后端存储设备构建虚拟存储节点，利用虚拟机多样化操作系统，以及动态迁移、快速部署等机制构建动态异构的存储系统架构.在拜占庭容错门限的基础上，提出自愈门限的概念，并设计相应系统安全协议，实现存储节点的自动化异常检测和状态复原.实验结果表明，提出的云存储系统具有较高的鲁棒性，能有效提高存储数据的安全性.

Abstract

For the problem of data security in the cloud storage system

a self-healing Byzantine Quorum system for the cloud storage security is proposed. In this system

the virtual machines are used as back-end storage devices to construct the virtual storage node. The diverse operating systems

dynamic migration and rapid generation mechanism of virtual machines are introduced to build dynamic and heterogeneous storage system architecture. On the basis of the Byzantine fault tolerance threshold

the concept of self-healing threshold is presented and several security protocols are devised to achieve automated anomaly detection and storage node recovery. The experimental results show that the proposed cloud storage system is greatly robust and can effectively improve the security of stored data.
