摘要
代理签名使原始签名者可以将其签名权利委托给代理签名者,从而代表原始签名者签名指定的消息.文章利用椭圆曲线上的双线性对性质,基于指定验证人签名和代理签名思想,提出了一个新的基于身份的指定验证人代理签名方案.该方案既具有基于身份签名的优点,又具有指定验证性,且安全性好.
Proxy signature is useful when an original signatory needs to delegate his or her signature capability to a proxy signatory, and the proxy signatory can signature messages on behalf of the original signatory. By the bilincar pairing defined on elliptic curves, and the ideas of designated verifier signature scheme and proxy signature scheme, a new ID-based designated verifier proxy signature scheme is proposed. The scheme can achieve confidentiality,designated verification and high security.
