Security of an Anonymous Key Agreement Protocol Based on Chaotic Maps

Abstract

Xue 與Hong 學者提出一個植基於混沌映射的匿名身分驗證協定，該驗證方法提供金鑰協議的功能。在詳細分析Xue 與Hong 學者的方法後，我們發現他們的方法無法並無法確保使用者的匿名性。在本論文中，我們將詳細說明Xue 與Hong 學者所提出方法的缺失。Xue and Hong proposed an anonymous authentication scheme with key agreement based on chaotic maps. After analyzing Xue and Hong’s scheme thoroughly, we find that their scheme cannot ensure user anonymity as claimed. In this paper, we will show this found security flaw which Xue and Hong’s scheme suffers from.
