Privacy-preserving MAX/MIN aggregation in wireless sensor networks

Advances in Information Sciences and Service Sciences 2012年第6期4卷 272-280页

作者： Yao, Yonglei Ma, Li Liu, Jingfa Jiangsu Engineering Center of Network Monitoring Nanjing University of Information Science and Technology Nanjing China School of Computer and Software Nanjing University of Information Science and Technology Nanjing China

In-network data aggregation has been adopted widely to reduce communication overhead and improve efficiency in wireless sensor networks. On the other hand, security is another basic requirement for wireless sensor network, and providing privacy without disrupting in-network data aggregation is a challenging problem. Although there have been extensive studies on privacy-preserving data aggregation for additive and multiplicative aggregation functions, nonlinear aggregation functions, such as maximum and minimum, have not been well addressed. In this paper, we present a privacy-preserving aggregation method specialized for MAX/MIN aggregation functions. To preserve privacy, encryption and the prefix membership verification scheme are employed, allowing an intermediate aggregator to correctly compare data without access to plaintext data, thus protect data privacy. Extensive simulations are conducted to evaluate the proposed schemes. The results show that our scheme provides privacy protection for both raw and aggregated data items, while achieving high efficiency in terms of energy consumption and time delay.

Efficient and secure multi-keyword ranked search over encrypted office open XML data

Journal of Computational Information Systems 2015年第7期11卷 2701-2708页

As cloud computing goes increasingly mature, searchable encryption schemes have been widely applied to the real world. Those not only provide high efficiency but also protect users' privacy well. However, the existing schemes mainly study plain text documents without any format information. In this paper, for the first time, we study and propose a secure and efficient multi-keyword search scheme over encrypted Office Open XML data (OOXML) documents. Specifically, a keyword red-black (KRB) tree is improved to adapt to format attribute-based keywords search. By recording format attribute (FA) of keywords, the returned results conform to users' search purpose well and own high relevancy. Extensive experiments on real-world dataset demonstrate the effectiveness of our scheme. ©, 2015, Binary Information Press. All right reserved.

第十届全国信息隐藏暨多媒体信息安全学术大会CIHW2012

作者： Jinwei WANG Xingming SUN Yuhui ZHENG Jin HAN Zhihua XIA Jiangsu Engineering Center of Network Monitoring Nanjing University of Information Science and Technology College of Computer and Software Nanjing University of Information Science and Technology China

With the development of the cloud environment, the multi-copyright protection of the works should be further developing. The multi-watermarking is becoming a possible solution. In this paper, firstly, one novel hybrid multi-watermarking rule is proposed, and is used to embed the watermark into DWT domain. Secondly, corresponding to the hybrid embedding rule, the novel optimum hybrid additive multi-watermarking decoder is proposed, which is based on the minimum Bayesian risk criterion, and simultaneously the performance of the hybrid decoder is theoretically analyzed. The DWT coefficients are modeled as the generalized Gaussian distribution. Finally, the theoretical and empirical experimental results prove the theoretical analysis validity.

Underwater sensor networks (UWSNs) are a class of emerging networks that experience variable and high propagation delays and limited available bandwidth. Because of the different environment under the ocean, the whole protocol stack should be re-designed to fit for the surroundings. In this paper, we only focus on the routing protocols in the network layer. We survey the state-of-the-art routing protocols and give a comparison of them with respect to the important challenging issues in UWSNs. The pros and cons are discussed and compared for the routing protocols. © Springer Science+Business Media Dordrecht 2014.

As the network communications technology developing, a new type of networks has appeared in the daily life which is named underwater sensor networks (UWSNs). Routing protocols in UWSNs should ensure the reliability of message transmission, not just decrease the delay. In this paper, we propose a novel routing protocol named Location-Aware Routing Protocol (LARP) for UWSNs, where the location information of nodes are used to help the transmission of the message. Simulation results show that the proposed LARP outperforms the existing routing protocols in terms of packet delivery ratio and normalized routing overhead. © Springer Science+Business Media Dordrecht 2014.
