dc.description.abstract	Alice and Bob meet in a campus bar in 2017. Being typical Virginia Tech students, they both have their genomes stored on their mobile devices and, before expending any unnecessary effort in courtship rituals, they want to perform a genetic analysis to ensure that their potential offspring would have strong immune systems and not be at risk for any recessive diseases. But Alice doesn't want Bob to learn about her risk for Alzheimer's disease, and Bob is worried a future employer might misuse his propensity to alcoholism. Two-party secure computation provides a way to solve this problem. It allows two parties to compute a function that depends on inputs from both parties, but reveals nothing except the output of the function. A general solution to this problem have been known since Yao's pioneering work on garbled circuits in the 1980s, but only recently has it become conceivable to use this approach in real systems. Our group has developed a framework for building efficient and scalable secure computations that achieves orders of magnitude performance improvements over the best previous systems. In this talk, I'll describe the techniques we use to design scalable and efficient secure computation protocols and report on some recent results in improving the security and performance of secure computing applications.
