S盒是通过有限域GF （28）上的乘法逆与1个可逆仿射变换合成的，它满足若干密码学性质，能够抵抗现有的各种攻击。但是由于构造A ES的S盒的方法只能用8×8的形式，而不能生成输入输出位数不等的S盒，这种局限性限制了S盒研究的发展空间。文章在分析多进制转换机制的基础之上，给出了 M进制与十六进制的转换方法，并将多进制与S盒进行组合，形成多进制组合多类S盒设计思想；通过C＃语言实现了多进制组合加密算法和A ES加密算法对图像加密的模拟实验，并对加密后的数据进行了测试分析，测试表明图像置乱效果增强。

The S-box ,which is synthesized with multiplicative inverse in the finite field GF (28 ) and a reversi-ble affine transformation ,meets certain cryptographic properties and is resistant to current various attacks . However ,as the S-box configured advanced encryption standard (AES) method can only be used in the form of 8 × 8 ,but cannot generate the input and output digits ranging from S cartridge ,S-boxes can be used in lim-ited area in the real world .In this paper ,the multi-binary conversion mechanism is analyzed ,and a M-ary hexadecimal conversion method is proposed .T hen the M-ary hexadecimal conversion method is imported into S-boxes ,and a new S-boxes strategy with M-ary hexadecimal conversion method is designed .Finally ,the simulation experiment of the benchmark image encryption is carried out by C # language to compare the pro-posed multi-band combination method of encryption algorithm and original AES encryption algorithm ,and the simulation results show that the image scrambling effect is largely enhanced by using the proposed algorithm .
