摘要
结合双线性对密码工具,提出了一种新的(t,n)门限代理签名方案.该方案的特点是:无需可信中心,减少了计算和通信量;原始签名者可以知道代理签名的生成者,同时接受者也可以证实签名者的真实身份.
In this paper, we propose a novel (t,n) threshold proxy signature scheme from bilinear pairings Our scheme has the following characteristic: without a trusted dealer, can reduce the amount of cornputations and communications, the original signer can know who generated the proxy signature and the receiver can certify the actuality of the group signers.
