Pasta: A Case for Hybrid Homomorphic Encryption

Transactions on Cryptographic Hardware and Embedded Systems, 2023
The idea of hybrid homomorphic encryption (HHE) is to drastically reduce bandwidth requirements when using homomorphic encryption (HE) at the cost of more expensive computations in the encrypted domain.

Multi-Key Homomorphic Encryption from TFHE

, 2019
In this paper, we propose a Multi-Key Homomorphic Encryption (MKHE) scheme by generalizing the low-latency homomorphic encryption by Chillotti et al. (ASIACRYPT 2016). Our scheme can evaluate a binary gate on ciphertexts encrypted under different keys followed by a bootstrapping.
