Abstract
Disclosed are systems, methods, devices, and computer-readable media for offloading lattice-based cryptographic operations to hybrid cloud computing system. In one embodiment, a method is disclosed comprising receiving a first network request from a client device via a secure application programming interface (API), the request including unencrypted data; encrypting the unencrypted data using an algorithm that generates homomorphically encrypted data; issuing a second network request to a second API of a cloud platform, the second network request including the encrypted data; receiving a response from the cloud platform in response to the second network request; and transmitting, in response to the first network request, a result to the client device based on the response, the result obtained by decrypting an encrypted output returned by the cloud platform.
