Analysis of One Popular Group Signature Scheme

Download www.iacr.org

The group signature scheme [1], ACJT for short, is popular. In this paper we show that it is not secure. It does not satisfy exculpability. The group manager can sign on behalf of any group member. The drawback found in the scheme shows that some inductions are not sound, though they are prevalent in some so-called security proofs. Keywords. group signature, exculpability, anonymity.
