计算机系统的安全性传统上与软件或正在处理的信息的安全性有关。用于信息处理的底层硬件被认为是可信的。硬件木马攻击的出现破坏了这一信任根源。这些攻击在电子硬件生命周期的不同阶段以恶意修改的形式出现，给电子行业带来了重大的安全问题。对手可以发起这样的攻击，其目的是导致操作失败或从芯片内部泄漏秘密信息，例如，密码芯片中的密钥。全球经济趋势鼓励在硬件设计和制造过程中增加对不可信实体的依赖，这正在迅速增强对此类攻击的脆弱性。在本文中，我们分析了硬件木马攻击的威胁;目前的攻击模型，类型和场景;讨论了不同形式的保护方法，包括主动和被动;并描述了新兴的攻击模式，防御和未来的研究途径。
Security of a computer system has been traditionally related to the security of the software or the information being processed. The underlying hardware used for information processing has been considered trusted. The emergence of hardware Trojan attacks violates this root of trust. These attacks, in the form of malicious modifications of electronic hardware at different stages of its life cycle, pose major security concerns in the electronics industry. An adversary can mount such an attack with an objective to cause operational failure or to leak secret information from inside a chip-e.g., the key in a cryptographic chip, during field operation. Global economic trend that encourages increased reliance on untrusted entities in the hardware design and fabrication process is rapidly enhancing the vulnerability to such attacks. In this paper, we analyze the threat of hardware Trojan attacks; present attack models, types, and scenarios; discuss different forms of protection approaches, both proactive and reactive; and describe emerging attack modes, defenses, and future research pathways.
