Large-Plaintext Functional Bootstrapping in FHE with Small Bootstrapping Keys

CoRR, 2023
Functional bootstrapping is a core technique in Fully Homomorphic Encryption (FHE). For large plaintext, to evaluate a general function homomorphically over a ciphertext, in the FHEW/TFHE approach, since the function in look-up table form is encoded in the coefficients of a test polynomial, the degree of the polynomial must be high enough to hold the ...

Bootstrapping outperforms community‐weighted approaches for estimating the shapes of phenotypic distributions [PDF]

Methods in Ecology and Evolution, 2023
Estimating phenotypic distributions of populations and communities is central to many questions in ecology and evolution. These distributions can be characterized by their moments (mean, variance, skewness and kurtosis) or diversity metrics (e.g ...

GPU Acceleration for FHEW/TFHE Bootstrapping

Transactions on Cryptographic Hardware and Embedded Systems
Fully Homomorphic Encryption (FHE) allows computations to be performed directly on encrypted data without decryption. Despite its great theoretical potential, the computational overhead remains a major obstacle for practical applications.

High-veracity functional imaging in scanning probe microscopy via Graph-Bootstrapping

Nature Communications, 2018
Scanning probe microscopy methods can generate high-dimensional data sets that correspond to a low-dimensional sample. Here, Li et al. develop a graphical bootstrapping method to quantitatively visualize large-scale high-dimensional datasets.

Bootstrapping Homomorphic Encryption via Functional Encryption. [PDF]

IACR Cryptol. ePrint Arch., 2023
Homomorphic encryption is a central object in modern cryptography, with far-reaching applications. Constructions supporting homomorphic evaluation of arbitrary Boolean circuits have been known for over a decade, based on standard lattice assumptions. However, these constructions are leveled, meaning that they only support circuits up to some a-priori ...

Bootstrapping Long-Run Covariance of Stationary Functional Time Series

Forecasting
A key summary statistic in a stationary functional time series is the long-run covariance function that measures serial dependence. It can be consistently estimated via a kernel sandwich estimator, which is the core of dynamic functional principal ...
