Key Management for Wireless Sensor Networks in Hostile Environments
… when WSNs have to operate unattended in a hostile environment, such as battlefields. In such an environment, an adversary poses a physical threat to all the sensor nodes. An adversary may capture any node, compromising critical security data including keys used for encryption and …

Exploring application memory
… forensic situations could involve machines in hostile environments, and many acquisition techniques result in artifacts, which reduce the fidelity of the image and hinder the analysis phase. Although the kernel memory space has come a long way in being mapped, the state of application memory …

Designing for voice in the vacuum : property in citizenship for democratic equality for future spacefarers
The hostile environments of space will require that human life beyond Earth be mediated by many advanced technologies and the many operationally prescriptive systems needed to manage them. Such sociotechnical systems will be characterized by hierarchy, routine, and continuous monitoring. Any humans …

Ant colony optimization for agile motion planning
… particular interest is the case of operating in hostile environments with unknown threat locations. When a threat appears, a replan must be quickly formulated and executed. The use of terrain masking to hide from the threat is a vital tactic, which a good algorithm should exploit. In addition, …

Stability of secure routing protocol in ad hoc wireless network.
… present a new approach to security of access in hostile environments based on the history and relationships among the nodes and on digital operation certificates. We also propose an access activity diagram which explains the steps taken by a node. Security depends on access to the history of each …
