Financial Critical Infrastructure: A MAS Trusted Architecture for Alert Detection and Authenticated Transactions

Banking and financial system constitute a critical service for our economy. Being able to foreseen real time attacks and failures on financial institutions network is a crucial challenge. In order to face those problems, research tends to elaborate alert mechanisms in order to support risk assessment, analysis and mitigation solution for real time decision-making processes. Our previous works had proposed a multi-agent based architecture to support that alert mechanism. This architecture exploited the Multi-agent system technology and proposes a static assignment of functions to agents. This static assignment was a weakness because isolating an agent or breaking the communication channel between two of them created serious damage on the crisis management. In this paper, we complete our previous works and make mobile the assignment of functions to agents. Our approach exploits the concept of agent responsibility that we assigned dynamically to agent taking into consideration the agent trust.This mobile assignement is illustrated by a case study that aims at adopting agent´s secret key according to the sensibility of the financial context.
