Recently, Eschenauer and Gligor proposed a model for random key predistribution in distributed sensor networks. In this paper we study the security of this model against a semi-honest adversary who compromises nodes, and present a key establishment algorithm that is provably secure. This is the first and only protocol that can guarantee security against semi-honest adversaries in an analytical framework.
In this paper, we study the problem of anomaly detection in high-dimensional network streams. We have developed a new technique, called Stream Projected Outlier deTector (SPOT), to deal with the problem of anomaly detection from high-dimensional data streams. We conduct a case study of SPOT in this paper by deploying it on 1999 KDD Intrusion Detection application. Innovative approaches for training...
In this paper, we propose a blind image watermarking scheme based on bidimensional empirical mode decomposition (BEMD). BEMD is a possible 2D extension of empirical mode decomposition (EMD). We employ BEMD in watermark embedding and watermark extraction. In watermark embedding scheme at first, the original image is divided into K sub-images then in order to obtain a set of 2D-IMFs BEMD is applied...
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
