Bootstrapping in FHEW-like Cryptosystems

Proceedings of the 9th on Workshop on Encrypted Computing & Applied Homomorphic Cryptography, 2021
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 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 ...

Optimizing FHEW With Heterogeneous High-Performance Computing

IEEE Transactions on Industrial Informatics, 2020
The latest implementation of the fully homomorphic encryption algorithm (FHEW), FHEW-V2, takes about 0.12 s for a bootstrapping on a single-node computer. It seems much faster than the previous implementations. However, the 30-bit homomorphic addition requires 270 times of bootstrapping; plus those spent on key generation, the total elapsed time climbs

Accelerating bootstrapping in FHEW using GPUs

2015 IEEE 26th International Conference on Application-specific Systems, Architectures and Processors (ASAP), 2015
Recently, the usage of GPU is not limited to the jobs associated with graphics and a wide variety of applications take advantage of the flexibility of GPUs to accelerate the computing performance. Among them, one of the most emerging applications is the fully homomorphic encryption (FHE) scheme, which enables arbitrary computations on encrypted data ...
