Active Trust Management for Autonomous Adaptive Survivable Systems (ATM’s for AAss’s)
The traditional approaches to building survivable systems assume a framework of absolute trust requiring a provably impenetrable and incorruptible Trusted Computing Base (TCB). Unfortunately, we don’t have TCB’s, and experience suggests
متن کاملExercising 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...
متن کاملActive 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...
متن کاملOn 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...
متن کاملSmart Trust Management for Vehicular Networks
Spontaneous networks such as VANET are in general deployed in an open and thus easily accessible environment. Therefore, they are vulnerable to attacks. Trust management is one of a set of security solutions dedicated to this type of networks. Moreover, the strong mobility of the nodes (in the case of VANET) makes the establishment of a trust management system complex. In this paper, we present...
