摘要
编码密码技术由于具有抵抗量子算法攻击的优点受到了广泛的关注。针对消息的匿名保护问题,提出了一种基于编码的盲签名方案。消息拥有者通过哈希技术和盲化因子将消息进行不可逆和盲化处理后发送给签名人,签名人利用CFS(Courtois-Finiasz-Sendrier)签名方案完成盲化签名并发回给消息拥有者,消息拥有者可通过去盲获得签名。分析表明,新的方案不仅具有一般盲签名的基本性质,而且继承了CFS签名方案的安全性高、签名长度短等优点,能够有效抵抗量子算法的攻击。
Coding cryptography is widespread concerned because it has the advantages of resisting quantum algorithm. To protect the anonymous message, a kind of blind signature scheme based on coding was proposed. By Hash technique and blind factor, message owner sent irreversible and blinding message to the signer, signer completed blind signature by using Courtois- Finiasz-Sendrier （CFS） signature scheme and sent it back to the message owner, message owner obtained signature by blind removing operation. Analysis show that the new scheme not only has the basic nature of general blind signature, but also inherit the advantages of CFS signature scheme such as high security and short signature length, in addition, it can effectively resist attacks of quantum algorithm.
