| 摘 要： | 针对文献1]中提出的DES算法抗能量攻击设计方法，给出了对此方法的改进。改进后的设计方法与原方法相比，具有相同的能量攻击抵御能力。对改进算法的理论分析表明，此方法可适用于大多数分组密码算法的抗能量攻击设计，且相对于文献1]中的方法，当基于FPGA具体实现时，改进算法可以在保持原有运行速度不变的情况下，节省约80％的硬件存储资源消耗。

| Abstract: | Aimed at the DES design method against power analysis attacks mentioned in reference 1],an improved one is proposed.Compared with the method of reference 1],it has the same ability against the power analysis attacks.By analyzing the improved algorithm in theory,it is applicable for this method to make use of in the process of most of cipher algorithm's design and implementation against power analysis attacks.The improved algorithm,while implemented based on FPGA,can not only save about eighty percent hardware storage resources,but also keep the operation rate in the same time. |
