Active Trust Management for Autonomous Adaptive Survivable Systems

Exercising Qualitative Control in Autonomous Adaptive Survivable Systems

We seek to construct autonomous adaptive survivable systems that use active trust management to adapt their own behavior in the face of compromises in the computational environment. Active trust management maintains probabilistic trust models that indicate the trustworthiness of different resources for different tasks, and uses these models in rationally adapting allocations of computational re...

Active Trust Management for Adaptive Survivable Systems (ATM for ASS’s)

The Problem: Computer systems are under attack as they have never been before. Every day computer systems around the world are compromised: data is stolen, security is breached, services are denied. These attacks are enabled by flaws in our current operating system, application code and middleware. It would be nice to replace all this with new software that is based on provably impenetrable tru...

On Efficiency of Non-Monotone Adaptive Trust Region and Scaled Trust Region Methods in Solving Nonlinear Systems of Equations

In this paper we run two important methods for solving some well-known problems and make a comparison on their performance and efficiency in solving nonlinear systems of equations‎. ‎One of these methods is a non-monotone adaptive trust region strategy and another one is a scaled trust region approach‎. ‎Each of methods showed fast convergence in special problems and slow convergence in other o...

A New Adaptive Load-Shedding and Restoration Strategy for Autonomous Operation of Microgrids: A Real-Time Study

Islanding operation is one of the main features of a MicroGrid (MG), which is realized regarding the presence of distributed energy resources (DERs). However, in order to deal with the control challenges, which an MG faces during island operation, particularly when the transition is associated with certain excessive load, an efficient control strategy is required. This paper introduces a Centra...
