基于行为能力约束的服务动态授权管理研究

摘要

Aiming at the problem of inefficient in the traditional service dynamic composition which based on semantic, and low validity of authorization management, this paper proposed a service dynamic authorization management method based on action capacity restriction. Relied on the mathematical optimization model, the method described the path of the composition service, this paper shew the collaborative application service dynamic composition algorithm by the restriction relations between componential service. Based on the action capability restriction, put up the pretreatment of services composition semantic reasoning, and searched for the minimum capability of collaborative application service. Judged between the action capability which the require users hold and that the minimum requirements of the collaborative application service, the authorization would avoid the huge researching and reasoning calculation in the semantic services when the users entered their requirement.Experiment results show that the method enhances the automation and efficiency of the service authorization management, and will be more dynamic adaptability.%针对传统基于语义服务动态合成的低效率和授权管理的有效性不高,提出了基于行为能力约束的服务动态授权管理方法.该方法借助数学优化模型,对服务合成的路径进行了描述,根据成分服务间的约束关系提出了协同应用服务动态合成算法.基于行为能力约束,将服务合成的语义推理进行预先处理,探索构成协同应用服务的最小行为能力,根据服务请求用户所拥有的行为能力与协同应用服务所需的最小行为能力的关系进行判断授权,避免了用户提出服务请求时的大规模空间搜索和服务语义间的推理计算问题.实验结果分析表明,该方法提高了服务授权管理的自动化程度和有效性,并且具有较高的动态适应能力.
