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

Abstract Fully Homomorphic Encryption (FHE) is a cryptographic primitive that allows
performing arbitrary operations on encrypted data. Since the conception of the idea in …

In their Eurocrypt'21 seminal paper, Li and Micciancio presented a passive attack against
the CKKS approximate FHE scheme and introduced the notion of CPA D security. The …

Due to the increasing popularity of application scenarios such as cloud computing, and the
growing concern of users about the security and privacy of their data, information security …

Abstract The Ducas-Micciancio (DM/FHEW) and Chilotti-Gama-Georgieva-Izabachène
(CGGI/TFHE) cryptosystems provide a general privacy-preserving computation capability …

This paper develops Central Limit arguments for analysing the noise in ciphertexts in two
homomorphic encryption schemes that are based on Ring-LWE. The first main contribution …

Abstract At Eurocrypt $2021 $, Li and Micciancio demonstrated that the IND-CPA notion of
security is not sufficient to cover the passive security of approximate homomorphic …

In many real-world scenarios, there are cases where a client wishes to check if a data
element they hold is included in a set segmented across a large number of data holders. To …

In the context of fully-homomorphic-encryption, we consider the representation of large
integers by their decomposition over a product of rings (through the Chinese Remainder …

Abstract The adoption of Homomorphic Encryption (HE) and Secure Function Evaluation
(SFE) applications in the real world remains lim-ited, even nearly 50 years after the …
