Collaboration Access Control Model for MAS Based on Role and Agent Cooperative Scenarios

Nowadays intelligent multi-agent collaboration research focuses on role-based collaboration framework and approaches. In a large-scale distributed network environment, with shared resource and operations of MAS radically increasing, how to resolve their security question must be taken into account, and role-based collaboration access control could satisfy the requirement as a future direction in the field. But, so far there is little further research on the aspect. This paper proposes and formalizes a general collaboration access control model called CACM for MAS, based on role and agent cooperative scenario that is a new represented concept in the paper. Besides, the related infrastructure, key protocols and core algorithms including role migration, role conflict avoidance and role coordination mechanisms, are also specified in detail. At last, through a practical application based the model, we validate the model is valid and usable, effectively improving MAS security and efficiency
