A Holistic Approach to Key Generation Using Physical Unclonable Functions

我们提出了一种基于PUF的整体密钥生成方法。信息论建模和分析将提供关于从物理来源生成密钥的完整情景的基本观点，并将允许为使用PUF生成密钥制定新的概念和评估标准。基于这些结果，将开发新的算法概念，将从物理来源提取比特与纠错码相结合。目标是在不影响安全性的情况下最大化从PUF中检索到的密钥信息。在原型开发过程中，从硬件的安全性和成本两个方面对新概念进行了实现和分析。

We propose a holistic approach for PUF based key generation. Information theoretic modeling and analyses will provide a foundational view on the complete scenario of key generation from physical sources and will allow the development of new concepts and evaluation criteria for key generation using PUFs. Based on these results new algorithmic concepts will be developed integrating bit extraction from physical sources with error correction codes. Goal is to maximize the information retrieved from PUFs for a key without compromising security. During prototyping, the new concepts are realized and analyzed with respect to security and cost aspects in hardware.
