The cryptographic algorithm has been gradually improved in design, but its implementations are vulnerable to side-channel analysis (SCA). Generally speaking, adding a mask to the primitive is the best way to counteract SCA. In the high-order mask, the key to affecting performance and security lies in the multiplication design. Based on the research of the advanced encryption standard (AES) algorithm, internal round function structure, and zero-knowledge proof, a high-order AES mask scheme is designed to optimise the implementation. In this scheme, the substitution-box protects sensitive variables in the algorithm with the use of secure multiplication and secure inversion by column. The scheme named as in columns higher-order mask (ICHM), features low cost and high security. The result of the experiment proves the security and effectiveness of the ICHM.

高阶AES掩模抗功率攻击研究

密码算法在设计上已得到逐步改进，但是其实现方式容易受到边信道分析（SCA）的影响。一般来说，在原语上添加掩码是抵消SCA的最佳方法。在高阶掩码中，影响性能和安全性的关键在于乘法设计。基于对高级加密标准（AES）算法，内部舍入函数结构和零知识证明的研究，设计了一种高阶AES掩码方案来优化实现。在此方案中，替换框通过使用安全乘法和按列安全求逆来保护算法中的敏感变量。以列高阶掩码（ICHM）命名的方案具有低成本和高安全性的特点。
