Abstract

An accelerator includes a memory, a compute zone to receive an encrypted workload downloaded from a tenant application running in a virtual machine on a host computing system attached to the accelerator, and a processor subsystem to execute a cryptographic key exchange protocol with the tenant application to derive a session key for the compute zone and to program the session key into the compute zone. The compute zone is to decrypt the encrypted workload using the session key, receive an encrypted data stream from the tenant application, decrypt the encrypted data stream using the session key, and process the decrypted data stream by executing the workload to produce metadata.
