Fully Homomorphic Encryption without Modulus Switching

Fully Homomorphic Encryption without Modulus Switching

Explore a groundbreaking talk from Crypto 2012 on Fully Homomorphic Encryption (FHE) without modulus switching. Delve into the evolution of FHE, from its early days to the second generation, and understand the concept of FHE 101. Examine the challenges associated with modulus switching in the BGV12 scheme and discover an innovative solution: scale-independent FHE. Learn about scale-independent multiplication, binary decomposition, and how full homomorphism is achieved through bootstrapping. Gain insights into outsourcing computation privately and the future implications of this technology for secure data processing.
