While hardware resources for computation and data storage are now abundant,economic factors prevent specialized hardware security mechanisms from beingintegrated into commodity parts. System owners are caught between the need to exploitcheap, fast, commodity microprocessors and the need to ensure that critical securityproperties hold.This research will explore a novel way to augment commodity hardware after fabricationto enhance secure operation. The basic approach is to add a separate silicon layer,housing select security features, onto an existing integrated circuit. This 3-D Integrationdecouples the function and economics of security policy enforcement from theunderlying computing hardware. As a result, security enhancements are manufacturingoptions applicable only to those systems that require them, which resolves theeconomic quandary. We plan to identify a minimal and realizable set of circuit-levelsecurity capabilities enabled by this approach, which can be judiciously controlled bythe software layers. This will significantly assist in reducing both the software complexityoften associated with security mechanisms and system vulnerabilities.This research introduces a fundamentally new method to incorporate securitymechanisms into hardware and has the potential to significantly shift the economics oftrustworthy systems. A broader impact will result through collaborative and educationalactivities. Graduate and undergraduate student research associates will transferknowledge to future teachers, researchers and Information Assurance professionals;and project publications will provide direct technical transfer to the embedded-systemsand hardware-design communities.

虽然用于计算和数据存储的硬件资源现在很丰富，但经济因素阻碍了专门的硬件安全机制被集成到商品部件中。系统所有者既需要开发廉价、快速的商用微处理器，又需要确保关键安全属性保持不变。本研究将探索一种新的方法，在制造后增强商用硬件，以增强安全操作。基本的方法是在现有的集成电路上增加一个单独的硅层，容纳精选的安全功能。这种3-D集成将安全策略实施的功能和经济性从底层计算硬件中分离出来。因此，安全增强正在制造仅适用于需要它们的系统的选项，这解决了经济困境。我们计划确定通过这种方法实现的最小和可实现的电路级安全功能集，这些功能可以由软件层明智地控制。这将大大有助于降低通常与安全机制相关的软件复杂性和系统漏洞。这项研究介绍了一种将安全机制整合到硬件中的全新方法，并有可能显著改变可信系统的经济性。通过合作和教育活动将产生更广泛的影响。研究生和本科生研究助理将把知识传授给未来的教师、研究人员和信息保障专业人员；项目出版物将向嵌入式系统和硬件设计社区提供直接的技术转移。
