Detection errors such as false alarms and undetected faults are inevitable in any practical anomaly detection system. These errors can create potentially significant problems in …
Assuring communication integrity is a central problem in security. However, overhead costs associated with cryptographic primitives used towards this end introduce significant …
In networked systems, monitoring devices such as sensors are typically deployed to monitor various target locations. Targets are the points in the physical space at which events of …
Impact Factor: 23.2
A broad variety of problems, such as targeted marketing and the spread of viruses and malware, have been modeled as maximizing the reach of diffusion through a network. In …
Sensor networks monitoring spatially-distributed physical systems often comprise battery-powered sensor devices. To extend lifetime, battery power may be conserved using sleep …
Bug-bounty programs have the potential to harvest the effort and diverse knowledge of thousands of independent security researchers, but running them at scale is challenging due to …
We analyze a two-player zero-sum game between a steganographer, Alice, and a steganalyst, Eve. In this game, Alice wants to hide a secret message of length $k$ in a binary …
Technological networks (e.g. telephone and sensor networks, Internet) have provided modern society with increased efficiency, but have also exposed us to the risks posed by their …
We develop a formal non-deterministic game model for secure team composition to counter cyber-espionage and to protect organizational secrets against an attacker who tries to …
