Motivated by recent developments in physical-layer security and stochastic geometry, we
aim to characterize the fundamental limits of secure communication in wireless networks …

Information-theoretic security--widely accepted as the strictest notion of security--relies on
channel coding techniques that exploit the inherent randomness of the propagation …

In Part I of this paper, we introduced the intrinsically secure communications graph (iS-
graph)-a random graph which describes the connections that can be established with strong …

The ability to exchange secret information is critical to many commercial, governmental, and
military networks. Information-theoretic security-widely accepted as the strictest notion of …

The secrecy graph is a random geometric graph which is intended to model the connectivity
of wireless networks under secrecy constraints. Directed edges in the graph are present …

A new random geometric graph model, the so-called secrecy graph, is introduced and
studied. The graph represents a wireless network and includes only edges over which …

We consider the fundamental security limits of stochastic wireless networks in the presence
of colluding eavesdroppers. By establishing a direct connection with the single-input …

Motivated by information-theoretic security, the Poisson model for secure connectivity in
stochastic networks has recently received great attention. Although several expressions for …

In this paper, we consider end-to-end secure communication in a large wireless network,
where the locations of eavesdroppers are uncertain. Our framework attempts to bridge the …

The ability to exchange secret information is critical to many commercial, governmental, and
military networks. The intrinsically secure communications graph (iS-graph) is a random …
