一种支持信息检索的安全网络文件存储模型

网络技术的发展使利用网络进行文件存储和共享逐渐成为一种重要的网络应用模式。如何在网络上存储文件并实现安全有效的共享成为一个必须解决的问题。当前对安全的网络存储模型的研究大都集中在安全方面,对共享所必须的信息检索支持不充分,这大大影响了数据的共享性。本文提出了一种新型的网络存储系统模型,该模型综合运用了压缩、加密和信息检索等技术,能有效地解决信息发布中的网络存储的安全性和共享性问题。在原型系统上进行的实验表明,该模型具有良好的性能。

A Secure Network File Storage Model Supporting Information Retrieval

The rapid development of network technologies has seen the use of network as a media for file storage and sharing.Files stored on network are expected to be shared in a safe and effective manner.Most current researches on secure network storage focus solely on security and give little concern to support information retrieval and in turn affect information sharing.This paper presents a new network storage model which integrates the techniques in compression,encryption and information retrieval.It effectively satisfies the concern for both security and sharing.Its performance is also demonstrated via experiments on a prototype system.
