摘　　要：提出了一个基于身份的有向签名方案。此签名具有只有指定的接收者才能验证及不需要验证签名者的公钥证书的特征。在此基础上提出了一个基于身份的门限验证的有向签名方案。An efficient directed signature scheme based on identity is presented which makes use of bilinear parings on elliptic curves.The scheme has the property that the signature can only be verified by the designated signature receiver.(Based on the proposed dircted signature scheme,a threshold verifying directed signature scheme was proposed.The security of the schemes is consiedered.)
