Abstract

Abstract: To overcome the disadvantage of high consumption of energy and bandwidth when the existing cloud storage technology which is applied to the smartphone, based on the Dropbox platform as a cloud service provider, an efficient and safe File Management system based on Cloud Instances (FM-CI) was designed. FM-CI supported download, compress, encrypt, convert operations, and file transfer between two smartphone users' cloud storage spaces. In addition, due to frequent open cloud instances may still increase the cost of the user, a protocol for users to share their idle instances and a file transfer scheme for sharing instance was designed. Simulation results show that, FM-CI can efficiently complete the file operations with less time and bandwidth, and the performance of FM-CI is better than those of the latest cloud storage schemes.

Key words: cloud storage, smartphone, file management, cloud instance, energy, bandwidth

摘要： 针对现有云存储技术应用到智能手机上导致其能量和带宽消耗较大这一不足，以Dropbox平台作为云服务提供商，设计了一种基于云实例的高效安全的文件管理系统（FM-CI）。FM-CI支持下载、压缩、加密和转换操作，同时支持在两个智能手机用户的云存储空间之间进行文件传输。此外，考虑到频繁开启云实例仍然可能增加用户的成本，还给出了用户空闲实例共享协议和基于共享实例的文件传输方案。仿真实验结果表明，FM-CI能在消耗较少时间和带宽的前提下，高效地完成文件操作，且性能要优于目前最新的云存储方案。
