The ABAM introduces an agent to keep the negotiation process with no human intervention. Meanwhile, the ABAM specifies the format of a meta access control policy, and adopts credentials with flexible format to meet the requirements of access control policies instead of disclosing the whole contents of a certificate. Furthermore, the ABAM uses asymmetric functions with a high security intensity to encrypt the transmitting message, which can prevent information from being attacked. Finally, the ABAM presents a new negotiation protocol to guide the negotiation process. A use case is studied to illuminate that the ABAM is sound and reasonable. Compared with the existing work, the intelligence, privacy and negotiation efficiency are improved in the ABAM.展开更多

State of the art overviews of automated negotiation is given. The main barriers to automated negotiation such as protocol and ontology are discussed. Then, a model of automated negotiation is presented with the ontologies of roles and goods described by web ontology language （OWL）, the proposal strategies based on the information sets, and a set of rules for agent interaction. In this model, agents coming from different organizations can negotiate automatically based on common ontologies defined by OWL and formal protocol. This makes it possible for the automated negotiation to be performed in an open environment such as Internet, not merely in a closed system.展开更多
