Talk Title: Ignorance is Bliss: using cryptography to build systems with nothing to lose
Abstract: As social and financial interactions move online, computers store and compute on increasing amounts of sensitive personal information. While cryptography has offered us many theoretical tools to allow privacy-preserving computation on secret data, industry routinely uses cryptography merely to address basic threats such as third-party eavesdropping. This poses a problem, as there appears to be an increasing consensus -- even in industry -- that it is risky to trust service providers with access to this information. To address this, we need systems that provide useful features that users expect, but do not expose information to theft even when the provider is fully malicious. This approach does more than protect user privacy: if the system is ignorant of both data and cryptographic keys, system security may reduce to a simple matter of detection and re-initialization. In this talk, I will explore the challenges in building “intentionally ignorant” systems by examining the design of Zerocash, a deployed anonymous alternative to Bitcoin, and cryptographic attacks arising from failures in the design of Apple’s iMessage end-to-end encrypted messaging service.
Time and Location: 11:00AM, Hariri Seminar Room

Talk Title: Customizing the system stack for data processing on modern hardware
Abstract: Addressing such a challenge requires an effort that is beyond what can be typically done within a single layer of the system stack: applications are typically unaware of the run-time state of a machine and the OS does not know what are the goals of the applications. In my talk, I will give an overview of my ongoing research on "Database/Operating system Co-Design" and show the benefits of a holistic approach by opening the interfaces and customizing the system stack for modern data processing workloads.
Time and Location: 11:00AM, Hariri Seminar Room
