SoK: Towards CCA Secure Fully Homomorphic Encryption

Abstract

Fully homomorphic encryption (FHE) was realized by Gentry in 2009. Since then, the current FHE construction has an inherent theoretical problem: FHE schemes are not secure against adaptive chosen-ciphertext attacks (CCA2), since FHE is malleable by definition. We conduct a survey on the existing works to circumvent this problem toward achieving better security of FHE.
