TITLE: Computing Blindfolded: New Developments in Fully Homomorphic Encryption
Is it possible to delegate arbitrarily complex computation on data without giving away access to the data? This problem -- called "fully homomorphic encryption" -- has long been regarded as cryptography's prized holy grail, and calls for the ability to compute on encrypted data without decrypting it and without knowing any secret keys. Starting from Gentry's groundbreaking work, the last three years have witnessed a number of constructions of simpler, faster and stronger fully homomorphic encryption systems, involving novel mathematical techniques, and a number of new and exciting applications. We will tell the story of these developments and provide a glimpse of the exciting research directions that lie ahead.
