Homomorphic encryption (HE) is often viewed as impractical, both in communication and computation. Here we provide an additively homomorphic encryption scheme based on (ring) LWE with nearly optimal r...

Homomorphic secret sharing (HSS) is an analog of somewhat- or fully homomorphic encryption (S/FHE) to the setting of secret sharing, with applications including succinct secure computation, private ma...
Short Discrete Log Proofs for FHE and Ring-LWE Ciphertexts
Zero-Knowledge Proofs Bulletproofs FHE
2019/1/26
In applications of fully-homomorphic encryption (FHE) that involve computation on encryptions produced by several users, it is important that each user proves that her input is indeed well-formed. Thi...
Non-Interactive Zero Knowledge and Correlation Intractability from Circular-Secure FHE
NIZK LWE
2019/1/4
We construct non-interactive zero-knowledge (NIZK) arguments for NPNP from any circular-secure fully homomorphic encryption (FHE) scheme. In particular, we obtain such NIZKs under a circular-secure va...
Multikey fully homomorphic encryption (MFHE) allows homomorphic operations between ciphertexts encrypted under different keys. In applications for secure multiparty computation (MPC)protocols, MFHE ca...
The FHE (fully homomorphic encryption) schemes [7, 13] based on the modified AGCD problem (noise-free AGCD problem) are vulnerable to quantum attacks, because its security relies partly on the hardnes...

In this work, we propose a faster homomorphic linear transform algorithm for structured matrices such as the discrete Fourier transform (DFT) and linear transformations in bootstrapping.

Multi-key FHE BGV scheme ciphertext extension
2018/11/2
Multi-Key Full Homomorphic Encryption scheme (MKFHE) can perform arbitrary operation on encrypted data under different public keys (users), and the final ciphertext can be jointly decrypted. Therefore...

Can Bob give Alice his decryption secret and be convinced that she will not give it to someone else? This is achieved by a proxy re-encryption scheme where Alice does not have Bob’s secret but instead...
Quantum FHE (Almost) As Secure as Classical
fully homomorphic encryption learning with errors quantum computation
2018/4/12
Fully homomorphic encryption schemes (FHE) allow to apply arbitrary efficient computation to encrypted data without decrypting it first. In Quantum FHE (QFHE) we may want to apply an arbitrary quantum...
