This paper creates a risk management model of enterprise information based on graph theory and the multi-agent system, and discloses the relationship between agents and information elements. According to the OSI framework, five information elements were included in the modelling, namely, authentication, access control, data security, data integrity and non-repudiation. The potential functions were introduced to depict the interaction between various information elements: the attractive force means the agents hold the same opinions, and the repulsive force means the agents disagree with each other, calling for adjustment. The control law based on smooth potential functions was also adopted for the modelling process. Finally, the proposed model was proved innovative and effective through a simulation on five robots. The research findings shed new light on risk management of enterprise information.
