A Secured Multi Agent Architecture for Grid Computing
Grid computing provides big possibilities like resource sharing, resource virtualization, and capacity planning since diverse resources that are geographically dispersed are virtualized as a single entity. The associated security concerns are one of the key obstacles preventing grid computing from being broadly adopted and used. Users in a grid are concerned about the security of their assets and the privacy of their data. A host's security in terms of its data or virtual servers may be jeopardised when it interacts with a grid. By providing multilateral security, i.e., security for both the Grid client and the Grid supplier, our building design expands the degree of assurance that can be placed on the accuracy of a Grid calculation and the assurance of client-provided resources. We discuss the issue of ensuring security and present the multi-agent security construction analysis. The paper outlines a multi-agent strategy for protecting the grid environment's resources. The strategy is put forth to address the grid computing industry's growing, serious security issue. The paper defines a multi-agent security architecture that integrates the capabilities of agents with the Grid Security Infrastructure's basic security mechanism (GSI). A security Master agent and a few security task execution agents make up the strategy
Multi-Agent Systems for Scalable Internet of Things Security
Providing eïŹective and scalable real-time security to Inter- net of Things devices can be a challenging task given the limited computational capacity of the devices and the amount of network traïŹc that can be viewed at any given time. Multi- Agent Systems have proven to be a valuable tool within the areas of cyber security, distributed networks and legacy systems because of their scalable and ïŹexible architecture. In this paper we present a novel implementation of a Completely Decentralised Multi-Agent System for use within, or to support, Internet of Things networks through the distributed processing of security events to oïŹoad the computational cost of data processing from Internet of Things devices. The concepts of conditions and eïŹects are introduced to allow agents to describe digital evidence found in an abstract language instead of sharing individual pieces of data to mitigate concerns of data leakage in extended networks. Emphasis is placed upon the scalable architecture design al- lowing domain experts to independently create agents speciïŹc to a particular technology or application process which will automatically work with other existing agents without further conïŹguration
Une approche logicielle du traitement de la dyslexie : Ă©tude de modĂšles et applications
Neuropsychological disorders are widespread and generate real public health problems. In particular in our modern society, where written communication is ubiquitous, dyslexia can be extremely disabling. Nevertheless we can note that the diagnosis and remediation of this pathology are fastidious and lack of standardization. Unfortunately it seems inherent to the clinical characterization of dyslexia by exclusion, to the multitude of different practitioners involved in such treatment and to the lack of objectivity of some existing methods. In this respect, we decided to investigate the possibilities offered by modern computing to overcome these barriers. Indeed we have assumed that the democratization of computer systems and their computing power could make of them a perfect tool to alleviate the difficulties encountered in the treatment of dyslexia. This research has led us to study the techniques software as well as hardware, which can conduct to the development of an inexpensive and scalable system able to attend a beneficial and progressive changing of practices in this pathology field. With this project we put ourselves definitely in an innovative stream serving quality of care and aid provided to people with disabilities. Our work has been identifying different improvement areas that the use of computers enables. Then each of these areas could then be the subject of extensive research, modeling and prototype developments. We also considered the methodology for designing this kind of system as a whole. In particular our thoughts and these accomplishments have allowed us to define a software framework suitable for implementing a software platform that we called the PAMMA. This platform should theoretically have access to all the tools required for the flexible and efficient development of medical applications integrating business processes. In this way it is expected that this system allows the development of applications for caring dyslexic patients thus leading to a faster and more accurate diagnosis and a more appropriate and effective remediation. Of our innovation efforts emerge encouraging perspectives. However such initiatives can only be achieved within multidisciplinary collaborations with many functional, technical and financial means. Creating such a consortium seems to be the next required step to get a funding necessary for realizing a first functional prototype of the PAMMA, as well as its first applications. Some clinical studies may be conducted to prove undoubtedly the effectiveness of such an approach for treating dyslexia and eventually other neuropsychological disorders.Les troubles neuropsychologiques sont trĂšs rĂ©pandus et posent de rĂ©els problĂšmes de santĂ© publique. En particulier, dans notre sociĂ©tĂ© moderne oĂč la communication Ă©crite est omniprĂ©sente, la dyslexie peut sâavĂ©rer excessivement handicapante. On remarque nĂ©anmoins que le diagnostic et la remĂ©diation de cette pathologie restent dĂ©licats et manquent dâuniformisation. Ceci semble malheureusement inhĂ©rent Ă la caractĂ©risation clinique par exclusion de la dyslexie, Ă la multitude de praticiens diffĂ©rents impliquĂ©s dans une telle prise en charge ainsi quâau manque dâobjectivitĂ© de certaines mĂ©thodes existantes. A ce titre, nous avons dĂ©cidĂ© dâinvestiguer les possibilitĂ©s offertes par lâinformatique actuelle pour surmonter ces barriĂšres. Effectivement, nous avons supposĂ© que la dĂ©mocratisation des systĂšmes informatiques et leur puissance de calcul pourraient en faire un outil de choix pour pallier les difficultĂ©s rencontrĂ©es lors de la prise en charge de la dyslexie. Cette recherche nous a ainsi menĂ© Ă Ă©tudier les techniques, aussi bien logicielles que matĂ©rielles, pouvant conduire au dĂ©veloppement dâun systĂšme bon marchĂ© et Ă©volutif qui serait capable dâassister un changement bĂ©nĂ©fique et progressif des pratiques qui entourent cette pathologie. Avec ce projet, nous nous plaçons dĂ©finitivement dans un courant innovant au service de la qualitĂ© des soins et des aides apportĂ©es aux personnes souffrant dâun handicap. Notre travail a ainsi consistĂ© Ă identifier diffĂ©rents axes dâamĂ©lioration que lâutilisation de lâoutil informatique rend possible. Chacun de ces axes a alors pu faire lâobjet de recherches exhaustives, de modĂ©lisations et de dĂ©veloppements de prototypes. Nous avons Ă©galement rĂ©flĂ©chi Ă la mĂ©thodologie Ă mettre en Ćuvre pour concevoir un tel systĂšme dans sa globalitĂ©. En particulier, nos rĂ©flexions et ces diffĂ©rents accomplissements nous ont permis de dĂ©finir un framework logiciel propice Ă lâimplĂ©mentation dâune plate-forme logicielle que nous avons appelĂ©e la PAMMA. Cette plate-forme devrait thĂ©oriquement pouvoir disposer de tous les outils permettant le dĂ©veloppement souple et efficace dâapplications mĂ©dicales intĂ©grant des processus mĂ©tiers. Il est ainsi attendu de ce systĂšme quâil permette le dĂ©veloppement dâapplications, pour la prise en charges des patients dyslexiques, conduisant Ă un diagnostic plus rapide et plus prĂ©cis ainsi quâĂ une remĂ©diation plus adaptĂ©e et plus efficace. De notre effort dâinnovation ressortent des perspectives encourageantes. Cependant, ce type dâinitiative ne peut se concrĂ©tiser quâautour de collaborations pluridisciplinaires disposant de nombreux moyens fonctionnels, techniques et financiers. La constitution dâun tel consortium semble donc ĂȘtre la prochaine Ă©tape nĂ©cessaire Ă lâobtention des financements pour rĂ©aliser un premier prototype fonctionnel de la PAMMA, ainsi que de premiĂšres applications. Des Ă©tudes cliniques pourront ĂȘtre alors menĂ©es pour prouver indubitablement lâefficacitĂ© dâune telle approche dans le cadre de la prise en charge de la dyslexie, ainsi quâĂ©ventuellement dâautres troubles neuropsychologiques
