安全服务质量(QoSS)的评价与控制模型研究

An Evaluation and Control Model of Quality of Security Service(QoSS)

安全服务质量(QoSS)是评价安全系统能否满足用户安全功能需求的重要指标。论文首先给出了基于QoSS的安全服务向量的形式化定义,以方便用户表达和规范化各自的安全需求。然后,在此基础上,提出了一个安全服务质量的评价与控制模型,重点介绍了用户对安全服务满意程度和安全服务成本的计算方法,以及对QoSS进行控制的流程。

Quality of Security Service(QoSS) refers to the ability of the security system to meet the security functional requirements of users.Based on QoSS,a formal definition of security service vector is provided here,which helps users to articulate and standardize their security requirements.And then,an evaluation and control model of QoSS is presented,in which the calculation method of users satisfaction degree and security services costs,and the control flow of QoSS,are introduced especially.
