Caihui Lan · Computer Technology and Development · 2008
Many existing threshold group signature schemes have the weaknesses that they are difficult to resist the conspiratorially attack from part of members,and they change a lot of parameters when group members added or deleted.According to the concept of class in some signature application,propose a new dynamic(1,t,n) threshold signature.The new scheme not only can avoid those weaknesses,but also can find out the subscriber after the event.
