项目摘要

As computing devices continue to be embedded in more and more physical devices, they are now privy to the most confidential information about our lives. The ability to safely keep a secret in memory is central to the vast majority of security systems, but storing and erasing these secrets is a difficult problem in the face of an attacker who can obtain unrestricted physical access to these devices and the underlying hardware. Depending on the memory technology, the very act of storing a 1 instead of a 0 can have physical side effects measurable even after the power has been cut. Through the development of a new class of architectures that measurably increase the difficulty of physical analysis this project is enabling systems that can be trusted even when physical control of the system is ceded to an adversary. Initial results indicate that the creation of an efficient scheme for memory protection is possible under which, even if an adversary is able to inspect the value of a stored bit with a probabilistic error of only 5%, the system will be able to prevent that adversary from learning any information about the original un-coded bits with 99.9999999999% probability. Over the long term this research will help to create the skills and tools that cyber-physical system engineers will need to develop pervasive trustworthy systems, and to ease the development of those mission critical systems that we all depend on for our safety and livelihood.

随着计算设备继续嵌入到越来越多的物理设备中，它们现在可以掌握有关我们生活的最机密信息。安全地保存秘密的能力是绝大多数安全系统的核心，但是在面对攻击者的情况下，储存和擦除这些秘密是一个困难的问题，他可以获得对这些设备和基础硬件的不受限制的物理访问。根据记忆技术，即使削减功率，存储1而不是0的行为也可以测量物理副作用。通过开发一类新的体系结构，这些结构可以衡量地增加物理分析的难度，即使将系统的物理控制割让给对手，该项目也可以信任系统。 Initial results indicate that the creation of an efficient scheme for memory protection is possible under which, even if an adversary is able to inspect the value of a stored bit with a probabilistic error of only 5%, the system will be able to prevent that adversary from learning any information about the original un-coded bits with 99.9999999999% probability.从长远来看，这项研究将有助于创建网络物理系统工程师将需要开发普遍可信赖的系统所需的技能和工具，并减轻我们所有人都为了安全和生计而依靠的关键任务关键系统的开发。
