摘　　要：针对集成电路芯片在制造过程中可能被嵌入恶意硬件电路、形成硬件木马这一问题,提出一种新的硬件木马设计技术.利用扩频通信原理,对芯片中的密钥或秘密数据进行扩频调制,有意形成器件噪声级别以下的电磁泄漏旁路,然后通过相关性分析技术提取秘密信息.对示例性AES(advanced encryption standard)密码电路的攻击实验表明,该硬件木马利用15 800个电磁信号样本,成功获取了AES中的8bit密钥.Integrate circuits （ICs） may be inserted malicious circuits as a hardware trojan during fabrication, a novel hardware trojans design technique is proposed. Based on the concepts of spread spectrum communications, the key or secret data in the ICs are modulated to intentionally form electro- magnetic emanation （EM） side channel leakage whose magnitude is much smaller than noise. And the secret information contained in the EM side channel leakage is extracted with correlation analysis. The experiment on a prototype AES（advanced encryption standard） chip showed that 8 bit AES key was recovered with 15 800 EM signal samples by inserting a hardware trojan in the AES circuits.
