Um estudo sobre esquemas totalmente homomórficos sobre números inteiros
This article has the objective of presenting a general state-of-art study about the main fully homomorphic encryption systems, with a focus on system based in integer algebra, specially the DGHV scheme and the improvements proposed by Coron. We made a mapping and a in deep study about the main fully homomorphic cryptosystems, from the original thesis by Gentry, in 2009, to more recent studies, like the schemes based on the learning with errors problem, and the key reduction techniques proposed by Coron.
