Fully Homomorphic Encryption (FHE) is a powerful cryptographic primitive that enables
performing computations over encrypted data without having access to the secret key. We …

Data privacy concerns are increasing significantly in the context of the Internet of Things,
cloud services, edge computing, artificial intelligence applications, and other applications …

With the increased need for data confidentiality in various applications of our daily life,
homomorphic encryption (HE) has emerged as a promising cryptographic topic. HE enables …

In this series of work, we aim at improving the bootstrapping paradigm for fully homomorphic
encryption (FHE). Our main goal is to show that the amortized cost of bootstrapping within a …

Bootstrapping is a term used very often in the context of Fully Homomorphic Encryption
(FHE). Anyone who is familiar with FHE knows that bootstrapping is the most sophisticated …

Blind rotation is one of the key techniques to construct fully homomorphic encryptions with
the best known bootstrapping algorithms running in less than one second. Currently, the two …

Homomorphic Encryption (HE) makes it possible to compute on encrypted data without
decryption. In lattice-based HE, a ciphertext contains noise, which accumulates along with …

Amortized bootstrapping offers a way to refresh multiple ciphertexts of a fully homomorphic
encryption scheme in parallel more efficiently than refreshing a single ciphertext at a time …

Abstract Threshold Fully Homomorphic Encryption (ThFHE) enables arbitrary computation
over encrypted data while keeping the decryption key distributed across multiple parties at …

BGV and BFV are among the most widely used fully homomorphic encryption (FHE)
schemes. Both schemes have a common plaintext space, with a rich algebraic structure. Our …
