基于专家综合评判的叛逆追踪效能评估研究

Research on expert comprehensive evaluation for traitor tracing effectiveness

针对追踪的效能评估显得尤为必要但至今尚缺,首次系统地通过理论方法结合实例模型,设计了对叛逆追踪效能进行评估的方法。首先实施专家咨询确定对影响叛逆追踪效能的因素分别从有效性、安全性、开销、完善性、应用性等五方面进行分析;然后层次分析确定各项的等级描述并构建叛逆追踪效能评估指标体系;最后综合评判某个叛逆追踪算法的效能。通过实例模型验证了其可操作性和优越性,且谓之专家综合评判。

Combining with theoretical method and actual example scientifically,this paper designed an evaluation method of traitor tracing effectiveness grade for the first time.It ascertained to analyze the effectiveness of one traitor tracing scheme from availability,security,overhead,integrity,and applicability by implementing Delphi firstly.Then it made sure their various grade descriptions and set up effectiveness valuation index sign system of traitor tracing by AHP.And finally it synthesized the effectiveness grade of adjudicating the current traitor tracing scheme.The method has been proved its maneuverability and superiority by actual example which is called as expert comprehensive evaluation.
