联合指名代理签名方案

Joint nominative proxy signature scheme

将指名代理签名和多重签名的思想结合起来,提出了联合指名代理签名方案,可有效地解决多位原始签名者同时委托一位代理签名者签名的问题.同时,为了保护代理签名者的身份隐私,进一步给出了一种加强的联合指定代理签名方案,将代理签名者的身份隐藏在某个别名下,只有可信的注册中心才能公开该代理签名者的身份.

This paper presents a joint nominative proxy signature scheme by combining the methods of nominative proxy signatures and multi-signatures, which can be used to solve the problem of signing on a document by multiple original signers efficiently. Also, an improved scheme is further proposed to protect the proxy＇s privacy, and the identity of the proxy signer is hidden behind an alias, with only a trusted registration center revoking his or her identity.
