摘要:

Web 服务是在商业社会中兴起的一种新的Web 应用。伴随着Web服务的发展,服务和服务请求者的数量变得越来越多,如何保障服务的利益和如何在海量的服务请求者中选择诚实的服务请求者将变得十分重要和困难,而现有的基于反馈的信任管理惩罚机制对于恶意的服务请求者缺乏有效的识别方法和惩罚机制。针对Web服务中缺乏对恶意服务请求者实施有效处罚机制的问题,本文在基于反馈的信任管理机制基础上,提出了一种反馈与时间衰减结合的信任管理机制,激励服务请求者提供诚实的访问行为,有效避免其对服务造成伤害,增强了Web服务的访问控制安全。

Abstract:

Web Services are a new kind of Web application in business. With the development of Web Services there are more and more requesters and services. How to protect the services and how to choose the honest requesters through thousands of requesters are very difficult and important. The existing trust management mechanism cannot publish the dishonest requesters due to its poor identification and punishment functions. In order to solve the issue of lacking effective punishment to malicious requesters in Web Services, this paper proposes a trust management mechanism based on feedback and time decay, which can encourage the requesters to provide honest access behaviors, effectively avoid damaging to the services, and enhance the security of access control in Web Services.

Key words: Web services;trust management;feedback;time decay
