Secure Fully Homomorphic Authenticated Encryption [PDF]
IEEE Access, 2021 Homomorphic authenticated encryption allows implicit computation on plaintexts using corresponding ciphertexts without losing privacy, and provides authenticity of the computation and the resultant plaintext of the computation when performing a ...

An overview of torus fully homomorphic encryption [PDF]
International Journal of Group Theory, 2023 The homomorphic encryption allows us to operate on encrypted data, making any action less vulnerable to hacking. The implementation of a fully homomorphic cryptosystem has long been impracticable. A breakthrough was achieved only in 2009 thanks to Gentry

Fully Composable Homomorphic Encryption [PDF]
IACR Communications in CryptologyThe traditional definition of fully homomorphic encryption (FHE) is not composable, i.e., it does not guarantee that evaluating two (or more) homomorphic computations in a sequence produces correct results. We formally define and investigate a stronger notion of homomorphic encryption which we call "fully composable homomorphic encryption", or ...

Efficient Leveled (Multi) Identity-Based Fully Homomorphic Encryption Schemes
IEEE Access, 2019 The first identity-based fully homomorphic encryption (IBFHE) scheme was constructed from identity-based encryption (IBE) and lattice-based cryptography by Gentry, Sahai, and Waters in CRYPTO 2013. Their IBFHE scheme is improved in this paper, exploiting

Fully Homomorphic Encryption [PDF]
Proceedings of the 2nd international Conference on Big Data, Cloud and Applications, 2017 In this paper we consider fully homomorphic encryption based on the learning with errors problem. We present the problem as introduced by Oded Regev in 2009 and explain a simple public key cryptosystem based on it. We show how the scheme can be modified to be more suitable for homomorphic operations, and introduce bootstrapping, using the ideas ...

CHIMERA: Combining Ring-LWE-based Fully Homomorphic Encryption Schemes
Journal of Mathematical Cryptology, 2020 This paper proposes a practical hybrid solution for combining and switching between three popular Ring-LWE-based FHE schemes: TFHE, B/FV and HEAAN. This is achieved by first mapping the different plaintext spaces to a common algebraic structure and then ...

SoK: Fully Homomorphic Encryption Accelerators
ACM Computing SurveysFully Homomorphic Encryption (FHE) is a key technology enabling privacy-preserving computing. However, the fundamental challenge of FHE is its inefficiency, due primarily to the underlying polynomial computations with high computation complexity and extremely time-consuming ciphertext maintenance operations.

On Fully Homomorphic Encryption [PDF]
, 2012 Fully homomorphic encryption is an encryption scheme where a party can receive encrypted data and perform arbitrary operations on this data efficiently.The data remains encrypted throughout, but the operations can be done regardless, without having to know the decryption key.Such a scheme would be very advantageous, for example in ensuring the privacy ...
