Abstract
Secure memory sharing between enclaves (virtual machines) and virtual input/output adapters includes, in response to a request for an enclave to create a virtual input/output adapter, creating a virtual input/output adapter associated with the enclave, creating a non-sharable micro-enclave, to contain only data, nested within the enclave to use with the virtual input/output adapter, generating a key by a memory encryption engine of an ultravisor for the virtual input/output adapter for use by only the virtual input/output adapter, in response to a request to obtain data from the enclave by the virtual input/output adapter, exchanging the key with the non-sharable micro-enclave, in response to receiving the key, decrypting memory of only the non-sharable micro-enclave associated with the virtual input/output adapter to obtain the data, and sending the data from the non-sharable micro-enclave nested within the enclave to the virtual input/output adapter.
