Universal Location Referencing and Homomorphic Evaluation of Geospatial Query
Location privacy Geohashing Spatial cloaking
2019/7/17
Location data is an important piece of contextual information in location-driven features for geosocial and pervasive computing applications. In this paper, we propose to geo-hash locations using spac...
Simulating Homomorphic Evaluation of Deep Learning Predictions
neural networks homomorphic encryption TFHE
2019/5/31
Convolutional neural networks (CNNs) is a category of deep neural networks that are primarily used for classifying image data. Yet, their continuous gain in popularity poses important privacy concerns...
Homomorphic Evaluation of Lattice-Based Symmetric Encryption Schemes
secret-key cryptography FHE
2018/7/9
Optimizing performance of Fully Homomorphic Encryption (FHE) is nowadays an active trend of research in cryptography. One way of improvement is to use a hybrid construction with a classical symmetric ...
New techniques for multi-value homomorphic evaluation and applications
lwe-based FHE multi-value bootstrapping homomorphic LUT
2018/6/25
In this paper, we propose a new technique to perform several homomorphic operations in one bootstrapping call over a multi-value plaintext space. Our construction relies on the FHEW-based gate bootstr...
Fast Homomorphic Evaluation of Deep Discretized Neural Networks
Fully Homomorphic Encryption Neural Networks Bootstrapping
2017/11/21
The rise of machine learning -- and most particularly the one of deep neural networks -- multiplies scenarios where one faces a privacy dilemma: either sensitive user data must be revealed to the enti...
We present a methodology to evaluate a Discrete Fourier Transform (DFT) on data which has been encrypted using a Somewhat Homomorphic Encryption (SHE) scheme, which is over 200 times faster than other...
Toward Practical Homomorphic Evaluation of Block Ciphers Using Prince
Homomorphic encryption NTRU Prince lightweight block ciphers
2016/1/23
We present the homomorphic evaluation of the Prince block cipher. Our leveled implementation is based on a generalization of NTRU. We are motivated by the drastic bandwidth savings that may be achie...
Accelerating Somewhat Homomorphic Evaluation using FPGAs
Somewhat homomorphic encryption NTT multiplication
2015/12/31
After being introduced in 2009, the first fully homomorphic encryption (FHE) scheme has
created significant excitement in academia and industry. Despite rapid advances in the last 6 years,
FHE schem...
Accelerating Homomorphic Evaluation on Reconfigurable Hardware
Homomorphic encryption ring learning with errors FPGA
2015/12/29
Homomorphic encryption allows computation on encrypted data and makes it possible
to securely outsource computational tasks to untrusted environments. However, all proposed
schemes are quite ineffic...
We show that homomorphic evaluation of any non-trivial
functionality of sufficiently many inputs with respect to any CPA secure
homomorphic encryption scheme cannot be implemented by circuits of
po...
