中文摘要: 高效可靠的授权策略是实现对数据资源有效管控的关键,但目前如何对其效率和可靠性进行测试评估尚无系统研究.首先,提出了一种量化开销计算方法(QCC,Quantitative Cost Calculation Method),通过区分错误授权判定和错误拒绝授权判定的方式改进了传统的开销评估方法,进而提出了一种以量化开销为决策依据的策略评估机制,给出了该机制运行流程的形式化描述.最后,通过对某综合网管系统日志数据的分析评估,验证了该机制的有效性.
Abstract:An efficient and reliable data resource authorization policy is the key of effective management, and there is no systemic study on how to make an evaluation on its efficiency and reliability. Firstly, QCC (Quantitative Cost Calculation Method) Method is proposed. Compared to the current methods, QCC makes a distinction between the wrong authorization judgment and wrong refused authorization judgment. And then a policy evaluation mechanism based on QCC is put forward. At last, by carrying out real policy evaluation analysis, we verify the effectiveness of the mechanism in improving the work efficiency with the real log data of an integrated network management system.
