摘要 首次利用双线性映射提出了一个基于身份的门限多代理多签名方案。在该方案中,原始群和代理群的管理员通过分发共享秘密来控制群成员的行为,在群成员获得共享秘密后,一定数量的原始签名者合作可以进行授权,一定数量的代理签名者合作可以产生签名。经分析得知方案具有秘密性、不可伪造性和不可否认性等安全特点。 This paper introduced an identity-based threshold multi-proxy multi-signature scheme using bilinear pairings for the first time.In this scheme,the administrators of the original group and proxy group could control the behavior of their members by distributing the shared secrets.After original signers and proxy signers obtained the shared secrets,some original signers could cooperatively delegate their signing capability to proxy signers,and some proxy signers could cooperatively generate threshold multi-pro...
