A Covert Channel Over VoLTE via Adjusting Silence Periods
IEEE Access, 2018 Covert channels represent unforeseen communication methods that exploit authorized overt communication as the carrier medium for covert messages. Covert channels can be a secure and effective means of transmitting confidential information hidden in overt

Behavior-Based Covert Channel in Cyberspace
, 2009 Many covert channels take advantages of weaknesses, flaws, or unused data fields in network protocols. In this paper, a behavior-based covert channel, that takes advantages of behavior of an application, is presented along with a formal definition in the

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Covert Channel in the BitTorrent Tracker Protocol
, 2012 Covert channels have the unique quality of masking evidence that a communication has ever occurred between two parties. For spies and terrorist cells, this quality can be the difference between life and death.

Advanced Engineering Materials, EarlyView.A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

ProtoLeaks: A Reliable and Protocol-Independent Network Covert Channel [PDF]
, 2020 . We propose a theoretical framework for a network covert channel based on enumerative combinatorics. It offers protocol independence and avoids detection by using a mimicry defense.
