多维度Web服务安全性评估

Multiple dimension security assessment of Web service

安全性已经成为Web服务质量的重要指标。通过增加Web服务安全评估中心扩展现有基本Web服务架构提出一个新的模型,并基于安全属性SoS(security of service)和用户偏好对Web服务进行安全性评估。结果表明,该模型能根据用户偏好修改安全属性的权重,并在提高服务选择的准确度和可用性方面都有较好的效果。

Security of Web service is an important indicator in quality of service. A new model was developed by adding se-curity evaluation center to expand the existing Web service model, and the security of Web services was evaluated based on security attributes and user＇s preferences. The results show that this model can set the security attributes according to user preference weights, and improve the accuracy and availability of service selection.
