| 摘 要： | 本文基于MI和TPM两类多变量公钥密码的公钥,利用"减"方法将其混合,提出了多变量数字签名方案的中心映射构造新方法,给出了基于MI和TPM混合的多变量数字签名方案,该方案能够有效抵抗高阶线性化方程攻击、秩攻击、XL&Grbner基攻击、差分攻击等现有典型攻击,并且与Rainbow、Sflashv2等典型多变量数字签名方案相比,在签名长度、密钥存储规模等方面具有优势.

| Abstract: | We use the method of minus to mix the public key of MI and TPM so that we propose a MPKC signature scheme based on MI and TPM.It is proved that the new scheme can resist high order linear equation attack,rank attacks,XL&Grbner basis attack,differential attack.It enhances security apparently and has some advantage on the length of signature,signature generation and the size of private key. |
