Better Bootstrapping in Fully Homomorphic Encryption
public-key cryptography / Bootstrapping Fully Homomorphic Encryption
2012/3/20
Gentry's bootstrapping technique is currently the only known method of obtaining a "pure" fully homomorphic encryption (FHE) schemes, and it may offers performance advantages even in cases that do not...
