STARSS: Small: New Attack Vectors and Formal Security Analysis for Integrated Circuit Logic Obfuscation

集成电路（IC）的逆向工程已经成为半导体设计公司的主要关注点，因为可以使用对IC进行拆包、延迟和成像的服务来提取底层设计。这种性质的IP盗窃不仅由于IP盗窃而产生经济影响，而且还危及军事和关键基础设施中使用的IC的安全性。该项目的目标是更深入地了解攻击者的能力，这些攻击者试图对使用当前方法伪装其设计的IC进行逆向工程，并根据这些新攻击开发更强大的伪装技术。 这个项目探讨了使用加密的逻辑混淆的安全性的基础分析。该项目为逻辑混淆开发了一个基本的安全度量标准，即D-安全性，它测量了攻击者需要知道的最少数量的输入模式，以便对电路进行解密。这项研究设计了强大而有效的decamberaging攻击，以了解现有方法中的漏洞，以及能够抵御这些攻击的新强化IC加密机制。这项工作解决了IC反向工程带来的经济和安全问题，并将纳入纽约大学的研究生和本科生课程以及纽约大学年度网络安全意识周的嵌入式系统挑战赛（ESC）中。

Reverse engineering of integrated circuits (ICs) has become a major concern for semiconductor design companies since services to depackage, delayer and image an IC can be used to extract the underlying design. IP theft of this nature has not only economic impact due to IP theft, but also compromises the security of ICs used in military and critical infrastructure. The goal of this project is to gain a deeper understanding of the capabilities of an attacker who is trying to reverse engineer ICs that use current methods to camouflage their design, and develops stronger camouflaging techniques in light of these new attacks. This project explores foundational analysis of the security of logic obfuscation using camouflaging. The project develops a fundamental security metric for logic obfuscation, D-security, that measures the minimum number of input patterns an attacker needs to know to decamouflage a circuit. This research devises strong and effective decamouflaging attacks in order to understand the vulnerabilities in existing approaches, and new fortified IC camouflaging mechanisms that are resilient to these attacks. This work addresses the economic and security concerns result from IC reverse engineering, and will be integrated in graduate and undergraduate coursework at NYU as well as in the Embedded Systems Challenge (ESC) at NYU's annual cyber-security awareness week.
