Distributed Reconfiguration for Resilient Synchronization of Multi-Agent Systems

Abstract

Les performances de la synchronisation de sortie dans les systèmes multi-agents (Mas) peuvent se dégrader en présence d'agents qui se comportent mal et qui sont affectés par des actions d'attaquants externes qui tentent de désynchroniser le système. Dans cet article, nous introduisons un algorithme heuristique basé sur les jeux de meilleure réponse pour définir une stratégie de reconfiguration distribuée en ligne pour atténuer dynamiquement ces actions, afin que le système atteigne un état de synchronisation. Cet algorithme fournit à chaque agent non attaqué une prise de décision basée sur des informations locales pour reconfigurer les modèles d'interaction avec ses voisins de sorte que le système se synchronise éventuellement. Nous présentons quelques simulations de la stratégie proposée pour plusieurs systèmes dans des scénarios réalistes pour montrer la capacité de l'algorithme proposé à atténuer différents types d'attaques.

El rendimiento en la sincronización de salida en sistemas multiagente (MAS) puede degradarse en presencia de agentes que se comportan mal y que se ven afectados por acciones de atacantes externos que intentan desincronizar el sistema. En este artículo, presentamos un algoritmo heurístico basado en juegos de mejor respuesta para definir una estrategia de reconfiguración distribuida en línea para mitigar dinámicamente estas acciones, para hacer que el sistema alcance un estado de sincronización. Este algoritmo proporciona a cada agente no atacado una toma de decisiones basada en información local para reconfigurar los patrones de interacción con sus vecinos de modo que el sistema finalmente se sincronice. Presentamos algunas simulaciones de la estrategia propuesta para varios sistemas en escenarios realistas para mostrar la capacidad del algoritmo propuesto para mitigar diferentes tipos de ataques.

The performance in output synchronization in multi-agent systems (MAS) can degrade in the presence of misbehaving agents that are affected by external attacker actions that try to desynchronize the system. In this paper, we introduce a heuristic algorithm based on best-response games to define an online distributed reconfiguration strategy to dynamically mitigate these actions, to make the system reach a synchronization state. This algorithm provides each unattacked agent with a decision-making based on local information to reconfigure the interaction patterns with its neighbors such that the system eventually synchronizes. We present some simulations of the proposed strategy for several systems in realistic scenarios to show ability of the of the proposed algorithm to mitigate different types of attacks.

يمكن أن يتدهور الأداء في مزامنة الإخراج في الأنظمة متعددة العوامل (MAS) في وجود عوامل سوء التصرف التي تتأثر بإجراءات المهاجم الخارجي التي تحاول إلغاء مزامنة النظام. في هذه الورقة، نقدم خوارزمية إرشادية تستند إلى ألعاب أفضل استجابة لتحديد استراتيجية إعادة التشكيل الموزعة عبر الإنترنت للتخفيف من هذه الإجراءات ديناميكيًا، لجعل النظام يصل إلى حالة المزامنة. توفر هذه الخوارزمية لكل عامل غير مهاجم عملية صنع قرار بناءً على المعلومات المحلية لإعادة تكوين أنماط التفاعل مع جيرانه بحيث تتم مزامنة النظام في النهاية. نقدم بعض عمليات المحاكاة للاستراتيجية المقترحة للعديد من الأنظمة في سيناريوهات واقعية لإظهار قدرة الخوارزمية المقترحة على التخفيف من أنواع مختلفة من الهجمات.
