SBIR Phase I: MEMS for Secure RFID Applications

这个小型企业创新研究（SBIR）第一阶段研究项目将确定MEMS谐振器的最佳配置，用作RFID标签中的唯一标识符。 MEMS谐振器具有高Q、高自然谐振频率，其在谐振器之间的频率变化。这种自然变化可用于唯一识别谐振器，并使克隆特定信号变得极其困难，本质上成为指纹。这种RFID安全方法克服了加密的缺点，包括更复杂和昂贵的标签以及需要管理加密密钥。用于RFID标签的MEMS谐振器将是独特的、安全的、成本有效的、CMOS兼容的、快速读取的、具有低功率要求和低开销的。这项研究将对提高识别人员和货物的安全性产生广泛的影响。例如，用于美国护照实施的RFID标签最近被克隆，这使这些标签的安全性受到质疑。由于MEMS谐振器无法克隆，因此它们可以提供重要的安全保证，以经济地验证给定的护照。类似的用途可以在安全网站的访问卡中找到。MEMS谐振器还可以用于经济地认证药品，因为假药越来越普遍并导致死亡。

This Small Business Innovation Research (SBIR) Phase I research project will determine the best configuration of MEMS resonators for use as unique identifiers in RFID tags. MEMS resonators have high Q, high natural resonant frequencies which vary in frequency from resonator to resonator. This natural variation can be used to uniquely identify a resonator, and makes cloning a specific signal extremely difficult, in essence becoming a fingerprint. This approach to RFID security overcomes the drawbacks of encryption which include more complex and expensive tags and the need to manage encryption keys. MEMS resonators for RFID tags will be unique, secure, cost effective, CMOS compatible, fast to read, with low power requirements and low overhead. This research will have a broad impact on improving the security of identifying people and goods. For example, the RFID tags used in the implementation of US passports were recently cloned which puts into question the security of those tags. Since MEMS resonators cannot be cloned, they can provide significant security assurance to economically validate a given passport. Similar uses can be found in access cards to secure sites. MEMS resonators can also be used to economically authenticate pharmaceuticals since counterfeit drugs are increasingly prevalent and have caused deaths.
