一种对无线传感器网络隐私保护数据聚合协议的攻击

An Attack on Privacy Preserving Data Aggregation Protocol for Wireless Sensor Networks

Jaydip Sen, Subhamoy Maitra

摘要:

在无线传感器网络(Wireless Sensor Networks,WSNs)中,网内数据聚合提供了高效的带宽利用率和节能的计算能力,支持高效的网内数据聚合同时保护单个传感器节点数据的隐私性已成为众多WSNs应用的重要需求。对于无线传感器网络中的隐私保护数据聚合,He等人(INFOCOM 2007)提出了一种基于聚类的私有数据聚合(CPDA),该聚合使用聚类协议和众所周知的密钥分配方案,用于以隐私保护方式计算加性聚合函数。尽管CPDA的广泛流行,它已被观察到,该协议是不安全的,它也是可能的,以提高其效率。在本文中,我们首先确定了现有的CPDA方案中的安全漏洞,其中我们展示了恶意参与节点如何可以发起攻击的隐私协议,以便获得其相邻传感器节点的私有数据的访问。接下来,它示出了如何现有的CPDA计划可以通过适当的修改协议更有效。此外,已经提出了对现有协议的适当修改,以便堵塞协议的脆弱性。

英文摘要:

In-network data aggregation in Wireless Sensor Networks (WSNs) provides efficient bandwidth utilization and energy-efficient computing.Supporting efficient in-network data aggregation while preserving the privacy of the data of individual sensor nodes has emerged as an important requirement in numerous WSN applications. For privacy-preserving data aggregation in WSNs, He et al. (INFOCOM 2007) have proposed a Cluster-based Private Data Aggregation (CPDA) that uses a clustering protocol and a well-known key distribution scheme for computing an additive aggregation function in a privacy-preserving manner. In spite of the wide popularity of CPDA, it has been observed that the protocol is not secure and it is also possible to enhance its efficiency. In this paper, we first identify a security vulnerability in the existing CPDA scheme, wherein we show how a malicious participant node can launch an attack on the privacy protocol so as to get access to the private data of its neighboring sensor nodes. Next it is shown how the existing CPDA scheme can be made more efficient by suitable modification of the protocol. Further, suitable modifications in the existing protocol have been proposed so as to plug the vulnerability of the protocol.
