On the ind-cca1 security of fhe schemes
Webone which supports single homomorphic operations, or a SHE/FHE scheme) cannot be IND-CCA2, but we have examples of singlely homomorphic and SHE IND-CCA1 schemes. The question then arises as to whether IND-CCA1 is the “correct” security definition, i.e. whether this is the strongest definition one can obtain for SHE schemes. WebHowever, while these FHE schemes are semantically (IND-CPA) secure, the question of their IND-CCA1 security is much less studied, and we therefore provide an overview of …

Webwork to investigate SHE schemes with IND-CCA1 security (i.e. secure against a non-adaptive chosen-ciphertext attack). At this moment, we have the following results. { No SHE and FHE scheme can be IND-CCA2 (secure against adaptive chosen-ciphertext attack). The reason is straightforward, based on the fact that the adversary is allowed retail hardware onlineWebleveled homomorphic encryption scheme. The scheme in question claimed to withstand precisely such attacks, and was the only scheme of its kind to do so at the time.
