Abstract: Multi-proxy blind signature is a special digital signature which satisfies the security properties of both the proxy signature and blind signature.It permits that an original signer authorizes a group of proxy signers who don’t know the concrete content of the message.A new multi-proxy blind signature is proposed based on DLP.This scheme doesn’t need security channel to transmit proxy cipher key,and has properities of unforgeability and unlinkability.

Key words: discrete logarithm problem, multi-proxy signature, blind signature, security channel, unforgeability, unlinkability

摘要: 多代理盲签名综合了多代理签名和盲签名的优点,是一种特殊的数字签名。它由一个原始签名人授权给一组代理签名人,并且这组代理签名人并不知道消息的具体内容。基于离散对数问题提出了一种新的多代理盲签名方案。该方案不需要安全信道传送代理密钥,且具有不可伪造性、不可链接性。
