In view of the fact that the traditional Hardware Trojan (HT) implanting method will increase the number of logic gates, and the power consumption changes obviously, this paper proposes a method of implanting HT in part of circuit by using evolvable hardware (EHW) technology. Firstly, the hierarchical clustering method is used to decompose the large-scale circuit, and then the EHW technology is used to redesign the decomposed sub circuit to make it have HT function. Finally, the original sub circuit is replaced by the evolved circuit, so as to achieve the effect of implanting hidden HT in part of circuit. The simulation results show that compared with the direct implantation method, the power change rate of the method is reduced by 35%, and the concealment is better.

鉴于传统的硬件特洛伊木马植入方法会增加逻辑门的数量，并且功耗会发生明显变化，因此，本文提出了一种采用可扩展硬件（EHW）技术在电路的一部分内植入丁苯橡胶的方法。 。首先，采用层次聚类法对大型电路进行分解，然后采用EHW技术对分解后的子电路进行重新设计，使其具有超线程功能。最后，将原来的子电路替换为进化后的电路，以达到在部分电路中植入隐藏的HT的效果。仿真结果表明，与直接植入方法相比，该方法的功率变化率降低了35％，隐蔽性更好。
