… Multipars (multi-party rust) because we implemented it … BGV encryption scheme and a
secure key generation protocol in Section 3. We show the 2s-enhanced CPA security of this BGV …

… Multiplication is the critical point in the BGV MultiKey cryptographic scheme, … key, also known
as the relinearisation key in the BGV scheme. To do so, we need to use all the parties’ keys, …

… look at the code available in the OpenFHE implementation of BGV and BFV. From this code,
… The idea is not to use a pure multi-party computation protocol, but to create a distributed key …

… key switching to our BGV instantiation and eliminate any multiprecision arithmetic from our

… Our implementation is based on a variant of the BGV scheme … of BGV-type cryptosystems is
