A Decade of Fully Homomorphic Encryption - Past, Present and Future

Explore the evolution and potential of fully homomorphic encryption (FHE) in this invited talk presented at Eurocrypt 2021. Delve into the remarkable transformation of FHE from a theoretical concept to a practical and usable tool over the past decade. Examine various homomorphic encryption schemes, including non-fully homomorphic ones, to understand the common techniques used to create semantically secure homomorphic encryption. Learn how masking techniques are employed to protect against common attacks, particularly those involving linear algebra. Gain insights into the future of FHE as the speaker outlines the search space for innovative schemes that go beyond the current framework. Discover the past, present, and future of this groundbreaking cryptographic technology through the expertise of Craig Gentry.
