一种基于ECO的实用的代工端木马插入

Side-Channel Trojan Insertion -- a Practical Foundry-Side Attack via ECO

Tiago Perez, Malik Imran, Pablo Vaz, Samuel Pagliarini

摘要:

设计公司通常将其集成电路(IC)制造外包给第三方,其中IC容易受到恶意行为的影响,例如插入侧信道硬件特洛伊木马(SCT)。在本文中,我们提出了一个框架,设计和插入SCT的基础上的工程变更单(ECO)流,这使得它第一次公开如何毫不费力地可以插入到IC木马。该木马的设计目标是在每次读取电源签名时泄漏多个位。我们的发现和结果表明,今天,铸造厂内的流氓元素拥有通过ECO执行铸造厂侧攻击所需的所有手段。

英文摘要:

Design companies often outsource their integrated circuit (IC) fabrication to third parties where ICs are susceptible to malicious acts such as the insertion of a side-channel hardware trojan horse (SCT). In this paper, we present a framework for designing and inserting an SCT based on an engineering change order (ECO) flow, which makes it the first to disclose how effortlessly a trojan can be inserted into an IC. The trojan is designed with the goal of leaking multiple bits per power signature reading. Our findings and results show that a rogue element within a foundry has, today, all means necessary for performing a foundry-side attack via ECO.
