Abstract
This paper describes a new forgery attack on the group-oriented (t, n) thre shold signature schemes proposed by Wang et al. Our attack is more fundamen tal than Tseng-Jan's attack in the sense that it cannot be recognized or bl ocked at the designated clerk level of the signature schemes. (C) 2001 Else vier Science B.V.
