摘要
多代理签名是一种特殊的数字签名技术,它允许一个原始签名人授权给一组代理签名人,让他们替代行使签名权.在盲签名中,消息的内容对签名者是不可见的,签名被用户泄露后,签名者不能追踪签名.结合多代理签名和盲签名,基于双线性配对首先设计了一个安全有效的多代理盲签名方案.该方案实现了多个代理签名人进行盲签名和公开信道授权.
Multi- proxy signature is a special digital signature technology, it means an original signet can authorize a group of proxy signers to sign on behalf of him. In a blind signature scheme, the signer cannot make a linkage between the signature and the identity of the user. Combining multi - proxy signature with blind signature, a multi - proxy blind signature scheme from bilinear pairings is proposed, which is secure and efficient. In the scheme, blind signature can be performed by multi proxy signers and delegation can be transmitted through public channel.
