Organizations move data and workloads to the cloud because the cloud is cheaper, more agile, and more secure. Unfortunately, the cloud is not perfect and there are some fundamental tradeoffs that need to be made in the cloud. The Cipherbase project studies the tradeoffs between confidentiality and functionality that arise when state-of-the-art cryptography is combined with databases in the cloud: The more operations that are supported on encrypted data, the more information that can be leaked unintentionally. There has been a great deal of work studying these tradeoffs in the specific context of property-preserving encryption techniques. For instance, deterministic encryption can support equality predicates directly over encrypted data, but it is also vulnerable to inference attacks. This talk discusses the tradeoffs that arise in a more general context when trusted computing platforms such as FPGAs or Intel SGX technology are used to process encrypted data.
Joint work with Arvind Arasu, Ken Eguro, Raghav Kaushik, Ravi Ramamurthy and the SQL Server Security Team.
Donald Kossmann is the director of the Microsoft Research Lab in Redmond. He joined Microsoft in 2014. Before that, he was a professor in the Systems Group of the Department of Computer Science at ETH Zurich (Switzerland). He is the Chair of ACM SIGMOD and an ACM Fellow. He is a co-founder of four start-ups in the areas of Web data management and cloud computing.
