摘要： 在D.Chaum建立的电子钱包的匿名性签名方案的基础上,针对D.Chaum的方案中存在的对犯罪嫌疑人不可追踪这一问题,提出了一个对犯罪嫌疑人可追踪的匿名性签名方案,即对于犯罪嫌疑人的合法签名,可以通过一个公正的第三方(如法院),找到这个用户的身份号(ID),从而完成对该ID的跟踪.与D.Chaum建立的电子钱包的匿名性方案相比,该方案在现实生活中更加具有实用性和有效性.

关键词: 电子钱包, 匿名性签名, 可追踪, 公钥, 身份号

Abstract: Based on the anonymous signature scheme of electronic wallet, as designed by D. Chaum, a traceable signature scheme for illegal user is presented to solve the problem that the illegal user is untraceable, i.e., a trusted third party such as the court can find the identity or ID number of the illegal user by his legal signature and, consequently, accomplish the ID tracing. Compared with the original scheme designed by D. Chaum, the new one is more practical and useful in actuality.
