Abstract

Multi-agent systems deal with interactive agents that possess somedegree of autonomy and cooperate towards the achievement of their goals.Multi-agent systems often need to operate in unsafe environments, andhence there is a need for situational awareness and risk assessment securitymechanism that can evaluate agent data to detect threats and analyse therisk posed by them. Basic belief-desire-intention (BDI) architecture lacksa framework that would facilitate effective communication, to bring about situational awareness among agents in an insecure environment. This paperaddresses the problems faced by a group of agents lacking global knowledge and global communications, by the introduction of a belief sharing andrisk assessment mechanism. We have extended basic BDI architecture withthe concept of situational awareness and adaptive risk management. Withthe proposed architecture, agents can gain awareness by exchanging beliefs,ascertaining the truth of such beliefs and measuring the credibility of a peeragent. Moreover agents can modify their level of alertness by monitoring the risks faced by them and by their peers. This enables the agents to detectand assess risks faced by them in an efficient manner, thereby increasingoperational efficiency and resistance against attacks.
