Towards Stream Ciphers for Efficient FHE with Low-Noise Ciphertexts

Explore a conference talk from Eurocrypt 2016 that delves into the development of stream ciphers for efficient Fully Homomorphic Encryption (FHE) with low-noise ciphertexts. Learn about outsourcing computation, FHE frameworks, and the SE-HE hybrid framework. Gain insights into performance metrics, state-of-the-art block and stream ciphers, and the innovative Filter Permutator construction. Discover how this approach impacts noise increase performances and compare it with existing solutions. Conclude by examining open problems in the field of efficient FHE implementations.
