摘要： 为实现数据的匿名性保护，提出一种基于McEliece公钥密码体制的盲签名算法。分别利用哈希技术和盲化因子对消息进行不可逆和盲化处理，通过McEliece公钥密码体制的加密算法完成签名，使用消息接收者去除盲化因子实现去盲操作，从而得到原始消息的签名。分析结果表明，该算法能保证隐私消息不会泄露，签名所用时间少于基于RSA体制的代理签名算法，并能抵抗量子计算机的攻击，安全性较好。

Abstract: A kind of blind signature algorithm based on McEliece Public Key Cryptography(PKC) is proposed to protect the anonymity of datas. Hash technology is used in the irreversible process. Blinding message is blinded by blind factor. It uses the McEliece PKC of the encryption algorithm to complete the signature in the last. A message receiver is used to remove blind factor to finish the blind removing operation. It gets the signature of the original message. Analysis results show that the algorithm can protect the privacy information from leaking out. Signing time is shorter than proxy signature algorithm based on RSA. It can resist quantum attacking and has better security.
