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&Gr bner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.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,XI＆Croner basis attack,differential attack.It enhances security apparently and has some advantage on the length of signature,signature geo.eration and the size of private key.
