Security key management is the most basic requirement for wireless sensor networks security. In this paper, we propose a dynamic key management scheme for large-scale clustering wireless sensor networks based on improved EBS. We use two one-way hash chains for nodes registration and verification, take half-symmetric t-degree trivariate polynomial keys to replace the original keys used in EBS, and...
Recently, Tsukada et al. propose to use multi-agent epistemic logic for a taxonomy of information-hiding/disclosure properties, in particular properties used in authentication protocols. We follow their proposal and introduce a new multi-agent justification logic for protocol analysis and verification. We show our logic at work analyzing a non-repudiation protocol due to Zhou and Gollmann. Based on...
Locally linear reconstruction (LLR) is a crucial step in the dimensionality reduction method called locally linear embedding (LLE), which aims to build a kind of weighted relationships for nearby data points. In this paper, we use this step in a different way to derive a new supervised classifier. The classifier labels a given test sample by checking which class of training samples can best reconstruct...
