Faster PCA and Linear Regression through Hypercubes in HElib
Leveled homomorphic encryption PCA Linear Regression
2018/9/6
The significant advancements in the field of homomorphic encryption have led to a grown interest in securely outsourcing data and computation for privacy critical applications. In this paper, we focus...
Faster Homomorphic Linear Transformations in HElib
Homomorphic encryption Implementation Linear transformations
2018/3/9
HElib is a software library that implements homomorphic encryption (HE), with a focus on effective use of "packed" ciphertexts. An important operation (which is used in bootstrapping, as well as in ot...
On dual lattice attacks against small-secret LWE and parameter choices in HElib and SEAL
learning with errors cryptanalysis homomorphic encryption
2017/2/20
We present novel variants of the dual-lattice attack against LWE in the presence of an unusually short secret. These variants are informed by recent progress in BKW-style algorithms for solving LWE. A...
HElib is a software library that implements homomorphic encryption (HE), specifically
the Brakerski-Gentry-Vaikuntanathan (BGV) scheme, focusing on effective use of the SmartVercauteren
ciphertext p...
Gentry’s bootstrapping technique is still the only known method of obtaining fully homomorphic
encryption where the system’s parameters do not depend on the complexity of the evaluated
functions. Bo...
