Blind aggregate signature scheme
Hao Chun-hui · Jisuanji gongcheng yu sheji · 2006
In an e-cash system,a user Alice obtains signing check from different banks(this is a process of getting blind signatures),and then she gives these checks to Bob.Bob verifies these checks in the different banks.Obviously,this progress will consume much time and storage.A blind aggregate signature scheme was presented.This scheme could give Bob a unique signature,which will save plenty of time and storage,and reduce the request of bandwidth.Because the scheme integrated the merits both of blind signature and aggregate signature,the signature produced by this scheme could be unique.
