Systems and methods of performing machine learning operations using secure enclaves

A system for performing a machine learning operation on a server host, the system comprising:

• a processor;
• and
• a memory coupled to the processor and storing a program executable by the processor to perform a method comprising:
• 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 comprising the machine learning operation;
• decrypting, in a secure enclave that is established by a secure environment, 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 the secure enclave, the secure enclave being protected from processes running at higher privilege levels;
• performing the machine learning 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 using the shared secret.
