研究了在ping-pong协议中比较不同检测策略效率的方法.分析了两种不同检测策略下窃听者可以得到的信息量和引入的干扰之间的约束关系,进而对两种策略进行了量化的比较.结果表明,用这种方法比较所得的结论与直观分析相吻合.因此,这种通过分析窃听发生时信息量与干扰之间约束关系来比较不同检测策略安全程度的方法是可行并且有效的.
We study the method of comparing the efficiency of different detection strategies in ping-pong protocol.We analyze the constraint relationship between the amount of information that can be obtained by eavesdroppers and the interference introduced by two different detection strategies, and then quantify the two strategies The results show that the results obtained by this method are in good agreement with the results of intuitionistic analysis.Therefore, this method of comparing the safety of different detection strategies by analyzing the relationship between the amount of information and the interference when eavesdropping occurs is feasible and effective .
