Bootstrapping in FHEW-like Cryptosystems [article]

Daniele Micciancio, Yuriy Polyakov
2020 IACR Cryptology ePrint Archive  
The FHEW cryptosystem was originally designed based on standard (Ring, circular secure) LWE assumptions, and its initial implementation was able to run bootstrapping in less than 1 second.  ...  FHEW and TFHE are fully homomorphic encryption (FHE) cryptosystems that can evaluate arbitrary Boolean circuits on encrypted data by bootstrapping after each gate evaluation.  ...  The security of the scheme is based on the fact that RLWE (and therefore also RLWE ) is circular secure, because an encryption of s can be trivially computed as the ciphertext (a, b) = (−1, 0), which,  ...

A Decade of Lattice Cryptography

Chris Peikert
2016 Foundations and Trends® in Theoretical Computer Science  
Lattice-based cryptography is the use of conjectured hard problems on point lattices in R n as the foundation for secure cryptographic systems.  ...  The main focus is on the foundational short integer solution (SIS) and learning with errors (LWE) problems (and their more efficient ring-based variants), their provable hardness assuming the worst-case  ...  I warmly thank Vadim Lyubashevsky, Dieter van Melkebeek, Oded Regev, Noah Stephens-Davidowitz, Madhu Sudan, and an anonymous reviewer for many valuable comments on earlier drafts.  ...

Parameter Optimization & Larger Precision for (T)FHE [article]

Loris Bergerat, Anas Boudi, Quentin Bourgerie, Ilaria Chillotti, Damien Ligier, Jean-Baptiste Orfila, Samuel Tap
2022 IACR Cryptology ePrint Archive  
In theory, Fully Homomorphic Encryption schemes allow to compute any operation over encrypted data.  ...  In this paper, we propose a framework of optimization to solve this open problem. Even though it mainly focuses on TFHE, the method is generic enough to be adapted to any FHE scheme.  ...  In FHE schemes, the technique used to reduce the noise is called bootstrapping. In TFHE-like schemes, bootstrapping is also able to evaluate a LUT at the same time.  ...

2021 arXiv   pre-print
In this paper, we present an in-depth architectural analysis of the bootstrapping step in FHE.  ...  The cost of the bootstrapping operation is one of the primary barriers to the wide-spread adoption of FHE.  ...  This slowdown is an inherent feature of all existing lattice-based FHE schemes. All of these schemes produce ciphertexts containing a noise term, which is necessary for security.  ...
