In order to reduce the impact of Hardware Trojan (HT) implantation on the original circuit power consumption, a method using Evolvable Hardware (EHW) to implant combinational HT is proposed. First, the truth table of the original circuit is modified according to the category of HT. Secondly, the symmetric value and similar value are used to evaluate the difficulty degree of evolution, and the truth table which is easy to evolve is selected for evolution. Finally, from the various circuits generated by evolution, the circuit close to the number of logic gates and power consumption of the original circuit is selected to replace the original circuit. The obtained circuit not only includes the HT function, but also improve the anti-power detection ability. According to the experimental results, the HT implanted by EHW has smaller power consumption difference than the HT implanted by general method, and has stronger anti-power detection ability.

为了减少硬件木马（HT）植入对原有电路功耗的影响，提出了一种利用可进化硬件（EHW）植入组合HT的方法。首先根据HT的类别修改原电路的真值表。其次，利用对称值和相似值来评价进化的难易程度，选择容易进化的真值表进行进化。最后，从进化产生的各种电路中，选择与原电路逻辑门数和功耗接近的电路来代替原电路。得到的电路不仅包含HT功能，还提高了抗功率检测能力。根据实验结果，
