Is the used scheme fully homomorphic encryption or just homomorphic wrt a specific operation? Because they only mention "homomorphic" without the "fully".

Swift Homomorphic Encryption implements the Brakerski-Fan-Vercauteren (BFV) HE scheme (https://eprint.iacr.org/2012/078, https://eprint.iacr.org/2012/144) (without bootstrapping). This is a leveled HE scheme, which supports a limited number of encrypted adds and multiplies (among other operations).

That’s awesome. I’m part of a cryptography group working on more applied uses of homomorphic encryption, is there a way to contact you?

With respect to IND-CCA, it doesn’t matter. Neither is compatible.
