TC: Large: Collaborative Research: 3Dsec: Trustworthy System Security through 3-D Integrated Hardware

虽然用于计算和数据存储的硬件资源现在很丰富，但经济因素阻止了专门的硬件安全机制集成到商品部件中。系统所有者在开发廉价、快速的商品微处理器的需求和确保关键安全特性的需求之间左右为难。本研究将探索一种新的方法，在制造后增加商品硬件，以增强安全操作。基本的方法是在现有的集成电路上添加一个单独的硅层，容纳选择的安全功能。这种3-D集成从底层计算硬件中实现了安全策略执行的功能和经济性。因此，安全增强是仅适用于需要它们的系统的制造选项，这解决了经济困境。我们计划确定一个最小的和可实现的一组电路级安全功能，使这种方法，可以明智地控制由软件层。这将大大有助于降低软件的复杂性往往与安全机制和系统漏洞。这项研究介绍了一个全新的方法，将安全机制纳入硬件，并有可能显着改变经济的可信系统。通过合作和教育活动将产生更广泛的影响。研究生和本科生的研究人员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;项目出版物将为嵌入式系统和硬件设计社区提供直接的技术转让。

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.
