Introduction to the BFV encryption scheme

February 7, 2021

In the last blog, we introduced the concept of Fully Homomorphic Encryption (FHE) and its capabilities. In this article, we will start a new blog series to dive deeper into the mathematical details of FHE and some of its popular encryption schemes. In particular, we will introduce the levelled Brakerski/Fan-Vercauteren scheme, a Ring-Learning with Errors (RLWE)-based cryptosystem. The readers will also learn about the fundamental operations commonly employed in FHE.
