Since the service aggregation aims to realize heterogeneous, multi state interactive process, the security access control models also required to acquire higher performance. Under the circumstances of service aggregation, in the paper, we propose an algorithm of cooperative aggregation of disparate services access control, named ACAHSP, to meet the requirements of service aggregation, dynamic access and centralized control. First, this paper analyzes the constitution of dynamic scene elements in the access of service aggregation, and defines different elements that constitute the scenarios from multiple perspectives. Then, this paper introduces the concept of dynamic situational finite state machine and presents a system of cooperation access gateway model which supports the calculations and rules of the situation under the constraint of dynamic situations. Moreover, based on the CP ABE algorithm, we propose the ACAHSP algorithm which strongly enhances the security of the finite state machine when changing and data exchanging during the process of service aggregation. Finally, the case study of music service aggregation demonstrates the feasibility and validation of the ACAHSP model compared with other traditional access control models and we then summarize the relative innovativeness between ACAHSP model and existing access control models.
