两个群签名方案的不可追踪性
On the untraceability of two group signatures
摘要
Abstract
Group signature allows individual members to make signatures on behalf of the whole group. It can be used to constitute a very useful basic tool in many settings, such as E-cash, E-auction and E-election. In this paper, by very simple attacks we show that the two group signatures proposed by Zhang et al in 2003 and Kim et al in 1996 are untraceable. In contrast to those attacks presented by Wang et al, the techniques developed in this paper are novel and interesting.关键词
