发布订阅系统中的隐私保护研究综述

发布订阅系统因其去耦合和异步的特性被广泛用于大规模的信息传输系统中,然而随着云计算和大数据的飞速发展,发布订阅系统的应用环境已经从封闭的可信计算环境转变为开放的不可信计算环境,隐私保护问题开始凸显.因此,总结目前发布订阅系统在隐私保护方面取得的研究成果、存在的问题以及可能的研究趋势具有重要意义.本文首先介绍了发布订阅系统模型,发布订阅系统中的隐私性定义,威胁模型等.然后介绍了发布订阅系统中实现机密性保护和匿名性保护的研究现状与进展.接着根据发布订阅系统隐私保护技术方法存在的不足展望了未来的研究方向,最后给出了本文的总结.

A Survey on Privacy Protection for Publish/Subscribe Systems

Publish/subscribe(Pub/Sub)systems are widely used in large-scale distributed systems due to their decoupling characteristics.However,with the development of cloud computing and big data,the application environment of publish/subscribe systems has changed from a closed trusted computing environment to an open untrusted computing environment,and privacy protection issues began to emerge.In order to summarize the research results,problems and possible research trends in the privacy protection of publish/subscribe systems,this paper first introduces the system model,privacy definition and threat model in publish/subscribe system,etc.,then introduces the research status and progress of confidentiality protection and anonymity protection in publish/subscribe systems.After that,the future directions of research are proposed according to the shortcomings of the privacy protection techniques for pub/sub systems.
