Local Information-Theoretic Security via Euclidean Geometry
Emmanouil M. Athanasakos, Nicholas Kalouptsidis, Hariprasad Manjunath
This paper introduces a methodology based on Euclidean information theory to investigate local properties of secure communication over discrete memoryless wiretap channels. We form…
Circular Super patterns and Zigzag constructions
Hariprasad Manjunath, Raisa Dsouza
In this article, we introduce the notion of circular k-superpatterns, defined as permutations that contain all length-k patterns up to rotation equivalence. We present a constructi…
Multi-Community Spectral Clustering for Geometric Graphs
Luiz Emilio Allem, Konstantin Avrachenkov, Carlos Hoppen +2
In this paper, we consider the soft geometric block model (SGBM) with a fixed number of homogeneous communities in the dense regime, and we introduce a spectral clusteri…
Sparse Regression Codes for Secret Key Agreement: Achieving Strong Secrecy and Near-Optimal Rates for Gaussian Sources
Emmanouil M. Athanasakos, Hariprasad Manjunath
Secret key agreement from correlated physical layer observations is a cornerstone of information-theoretic security. This paper proposes and rigorously analyzes a complete, constru…
