【摘要】：提出一种针对基于SM3的动态令牌实施的能量分析攻击新方法,首次提出选择置换函数的输出作为能量分析攻击的目标,并将攻击结果联立得到方程组。根据给出的逆置换函数求解方程组,即可破解最终的密钥。通过实测攻击实验,验证了该攻击方法的有效性,这就很好地解决了直接选择密钥作为能量分析攻击目标所产生的问题,同时,引入中间变量作为能量分析攻击目标破解密钥方法,还可以应用于针对其他密码算法的能量分析攻击中。
[Abstract]:A new method of energy analysis attack against dynamic token based on SM3 is proposed. It is the first time that the output of permutation function is chosen as the target of energy analysis attack, and the system of equations is obtained by combining the result of attack. The final key can be solved by solving the equations based on the given inverse permutation function. The effectiveness of the attack method is verified by the experimental results, which solves the problem of selecting the key directly as the energy analysis target. At the same time, The intermediate variable is introduced as the key cracking method for the energy analysis attack target, and it can also be applied to the energy analysis attack against other cryptographic algorithms.
