Abstract
Modern cryptography provides a rigorous mathematical framework for proving the security of cryptographic algorithms. To be effective, however, these mathematical models must accurately reflect the realities of cryptography's use in systems. In this talk, I will address mismatches between theory and use, giving several examples from my work: the problem of credit card number encryption, dealing with bad (cryptographic) randomness, the increasingly diverse applications of cryptographic hash functions, and privacy-preserving device tracking. In each example, problems arise because of gaps between what cryptography offers and what security and privacy demands. To fix these issues, I take an application-oriented approach. This involves modifying cryptography in a theoretically-sound to work better for systems, as well as understanding cryptography's role in broader system security mechanisms.
Looking forward, I will discuss my recent work on new attacks in the setting of cloud computing and my future plans for securing next-generation cloud computing services.
