Abstract: Anonymity is used in many schemes, but there is no accurate mathematical model to evaluate or compare anonymity. An entropy deviation model based on information entropy is proposed to compare the anonymity by quantifying anonymity. The model can be used to compare the anonymity of different systems. It seems to be objective and reasonable that weight is considered with every node according to its effects in anonymity system. The practicality of this model is illustrated with some examples, and then compared with other schemes, the results show the advantages of this model.

摘要: 匿名性是很多协议都会用到的一种属性,但是如何来对匿名性进行量化和对匿名程度进行比较,目前还没有一个准确的数学模型。基于信息熵理论提出了将匿名性量化后进行比较的信息熵偏差模型。该模型能够用于不同的系统之间匿名性的比较,并且根据各个节点对系统的影响,客观、合理地给出了各个节点的权重。举例说明了模型的实用性,并且与其他模型进行比较说明了该模型的优越性。
