SBIR Phase I: Zero-Remanence Tamper-Responsive Cryptokey Memory

这项小型企业创新研究（SBIR）项目将开发一种创新的非易失性自旋电子加密密钥存储器，该存储器可以在被篡改的情况下自动擦除，而不会留下数据残留，并且无需使用电源。磁随机存取存储器（MRAM）是唯一具有这种能力潜力的技术。防篡改MRAM可能是一个主要的范式转变-在检测到篡改时，目前ic中使用的存储器必须通过覆盖或断开电源来擦除。研究目标包括MRAM位形状的微磁研究，以消除直流场擦除后的数据残留，集成系统的有限元模拟，以确定最佳的磁铁/屏蔽/模具配置，自旋电子防篡改存储单元的制造，以及集成器件的红队分析。这项工作将通过使用自旋相关的隧道制造和模拟资源来完成。预期结果是1 kbit防篡改嵌入式MRAM设计和可行性分析。在商业上，这为基于ic的组件（如智能卡、自动取款机等）提供了一层额外的保护。此外，所提出的程序将使系统在物理篡改的情况下不可操作。这将是一个非常有用的工具，用于阻止欺诈使用或基于ic的工具的妥协以及某些类型的身份盗窃。某些组织以各种研究机构为目标，并试图通过攻击计算机系统来破坏他们的研究。这将为数据提供额外的保护。身份盗窃已经成为社会普遍存在的一个大问题，尤其是在计算机化程度更高的社会。

This Small Business Innovation Research (SBIR) project will develop an innovative non-volatile spintronic cryptographic key memory that can self-erase without data remanence in the event of tampering and without applied power. Magnetic Random Access Memory (MRAM) is the only technology with potential for this capability. Anti-tamper MRAM could be a major paradigm shift - memories used in ICs presently must be erased by overwriting or disconnection of a power source when tampering is detected. Research objectives include a micromagnetic study of MRAM bit shapes to eliminate data remanence after DC field erasure, finite elements simulation of the integrated system to determine optimal magnet/shield/die configurations, fabrication of spintronic anti-tamper memory cells, and red team analysis of the integrated device. This work will beaccomplished through use of spin-dependent tunneling fabrication and simulationresources. The anticipated result is a 1 kbit anti-tamper embedded MRAM design andfeasibility analysis.Commercially, this provides an extra layer of protection on IC-based assemblies such assmart cards, cash machines etc. In addition, the proposed program will render a systeminoperable in the event of physical tamper. This will be a very useful tool in stemmingthe tide of fraudulent usage or compromises of IC-based instruments as well as certaintypes of identify theft. Certain groups have targeted various research organizations andattempted to otherwise compromise their research through attacks on their computersystems. This would provide additional protection to the data. Identity theft has becomea very large issue for society in general and particularly in the more computerizedsocieties.
