Dual System Encryption via Predicate Encodings Friday, November 7, 2014 - 10:30am to 12:00pm Abstract: In this talk, I will present the notion of predicate encodings, an information-theoretic primitive reminiscent of linear secret-sharing that in addition, satisfies a novel notion of reusability. Using this notion, we obtain a unifying framework for adaptively-secure |

Strong Key Derivation from Noisy Sources Friday, December 12, 2014 - 10:30am to 12:00pm Abstract: A shared cryptographic key enables strong authentication. Candidate sources for creating such a shared key include biometrics and physically unclonable functions. However, these sources come with a substan |

Sergey Gorbunov: New Advances in Fuctional Encryption Friday, October 10, 2014 - 10:30am to 12:00pm Abstract: Functional encryption is an emerging vision for public-key cryptography offering fine-grained mechanism for computing on encrypted data. Unfortunately, currently all of the more powerful constructions of functional encryption are built from non |
