Abstract
  • The ability to create reproducible cryptographically secure keys from temporal environments (e.g., images) has the potential to be a contributor to effective cryptographic mechanisms. Due to the noisy nature of these environments, achieving this goal in a user friendly fashion is a very challenging task, especially since there exists a research gap to create reproducible keys from image data. In this thesis, towards addressing aforementioned challenge, we developed a new image based reproducible key derivation mechanism, which leverages deep learning technique along side with fuzzy-extractor schemes to enable reproducible symmetric key creation from temporal visual environments. Our technique uses deep learning and fuzzy-extractors as fundamental building blocks. Deep learning harnesses patterns in images to minimize the noise, and permit successful utilization of fuzzy-extractor schemes to handle errors by using error-correcting codes. Using these techniques together enables reproducible key generation. We also instantiated our technique to enable three potential use cases: i) Image entropy strengthened authentication, ii) image based password authenticated Diffie-Hellman, and iii) position based cryptography. Along side these potential use cases, we conducted a user study to assess the usability of the provided scheme.
