| | | | | Guest post by Boaz Barak and Zvika Brakerski (part 2) In the previous post, we demonstrated the versatility of fully homomorphic encryption and its applicability for multiple applications. In this post we will demonstrate (not too painfully, we hope) how fully homomorphic encryption is constructed. Our goal is to present the simplest solution that (we... | |

| | | | | The Learning With Errors problem is the basis of a few cryptosystems, and a foundation for many fully homomorphic encryption (FHE) schemes. In this article I'll describe a technique used in some of these schemes called modulus switching. In brief, an LWE sample is a vector of values in $\mathbb{Z}/q\mathbb{Z}$ for some $q$, and in... | |

| | | This half of the theory of computing primer will cover the various finite automata, including deterministic, nondeterministic, and pushdown automata. We devote the second half [upcoming] entirely to Turing machines and the halting problem, but to facilitate the discussion of Turing machines we rely on the intuition and notation developed here. Defining Computation The first... | ||
