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 timing channels in uncompromised hosts
, 2009 Covert timing channels have been considered a significant threat in multi-level systems (MLS) because of their capability in aiding information leakage across level boundaries leading to security policy violations.

Covert channels in the IP time to live field
, 2006 Covert channels are used for the secret transfer of information. Unlike encryption, which only protects the information from unauthorised observers, covert channels aim to hide the very existence of the communication.

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Joint Altitude and Power Optimization for Multi-UAV-Aided Covert Communication with Relay Selection
DronesUnmanned aerial vehicles (UAVs) are pivotal for 6G ubiquity, yet their open line-of-sight channels increase vulnerability to interception, posing new challenges for covert communication. This paper proposes a joint optimization scheme for multi-UAV relay-

On the Modelling, Analysis, and Mitigation of Distributed Covert Channels [PDF]
, 2015 Covert channels are means of communication that allow agents in a system to transfer information in a manner that violates the system’s security policy. Covert channels have been well studied in the constrained and old sense of the term where two agents ...

AutoCC: Automatic Detection of Microarchitectural Covert Channels
, 2023 Microarchitectural state can be used as a covert channel to leak information across security domains. In hardware that is shared between multiple processes, these channels can be used in attacks that break process isolation.
