Abstract
Methods and systems for performing a computational operation on a server host are provided. Exemplary methods include: receiving an encrypted service request from a client host, the client host encrypting a service request to produce the encrypted service request using a shared secret, the service request specifying the computational operation; decrypting, in a secure enclave, the encrypted service request using the shared secret to produce a decrypted service request, the secure enclave preventing other software running on the server host from accessing the shared secret and other data stored in a memory space; performing the computational operation, in the secure enclave, using the decrypted service request to generate a service result; encrypting, in the secure enclave, the service result using the shared secret to create an encrypted service result; and providing the encrypted service result to the client host, the client host decrypting the encrypted service result.
