Key predistribution schemes for distributed sensor networks have received significant attention in the recent literature. In this paper we propose a new construction method for these schemes based on combinations of duals of standard block designs. Our method is a broad spectrum one which works for any intersection threshold. By varying the initial designs, we can generate various schemes and t...

In these turbulent times, we propose the importance of developing the psychological capital dimension of resiliency. After providing the theoretical background and meaning of psychological capital in general and resiliency in particular, the authors present proactive and reactive human resource development (HRD) strategies for its development. The proactive HRD includes increasing psychological...

The views, opinions and/or findings contained in this report are those of The MITRE Corporation and should not be construed as an official government position, policy, or decision, unless designated by other documentation. Abstract This white paper describes how resiliency techniques apply to an acknowledged system-of-systems (SoS). MITRE's cyber resiliency engineering framework is extended, to...

The revision of the Ego Resiliency Scale (ER89) is described based on the self-reports of 754 Italian young adults. The dimensionality of the original instrument was explored through EFA and CFA; different factor structures across both gender and two random half-samples were investigated. Results provide evidence for a second-order model, based on two first-order factors (Optimal regulation and...

We propose SR3, a secure and resilient algorithm for convergecast routing in WSNs. SR3 uses lightweight cryptographic primitives to achieve data confidentiality and data packet unforgeability. SR3 has a security proven by formal tool. We made simulations to show the resiliency of SR3 against various scenarios, where we mixed selective forwarding, blackhole, wormhole, and Sybil attacks. We compa...

Exposing the rate information of wireless transmission enables highly efficient attacks that can severely degrade the performance of a network at very low cost. In this paper, we introduce an integrated solution to conceal the rate information of wireless transmissions while simultaneously boosting the resiliency against interference. The proposed solution is based on a generalization of Trelli...

As it stands, the DSM fails to address important sources of strength and resiliency that can significantly affect diagnosis and treatment. The authors of this transformative volume propose enhancements to the current diagnostic and classification system that encompass the biopsychosocial, cultural, and spiritual milieus of individuals and acknowledge the strengths originating from personal, fam...

Real-time transmission of video data in network environments, such as wireless and Internet, is a challenging task, as it requires high compression efficiency and network friendly design. H.264/AVC is the newest international video coding standard, jointly developed by groups from ISO/IEC and ITU-T, which aims at achieving improved compression performance and a network-friendly video representa...

Extreme-scale parallel systems will require alternative methods for applications to maintain current levels of uninterrupted execution. Redundant computation is one approach to consider, if the benefits of increased resiliency outweigh the cost of consuming additional resources. We describe a transparent redundancy approach for MPI applications and detail two different implementations that prov...
