Abstract
Technologies for secure I/O data transfer include a computing device having a processor and an accelerator. Each of the processor and the accelerator includes a memory encryption engine. The computing device configures both memory encryption engines with a shared encryption key and transfers encrypted data from a source component to a destination component via an I/O link. The source may be processor and the destination may be the accelerator or vice versa. The computing device may perform a cryptographic operation with one of the memory encryption engines and bypass the other memory encryption engine. The computing device may read encrypted data from a memory of the source, bypass the source memory encryption engine, and transfer the encrypted data to the destination. The destination may receive encrypted data, bypass the destination memory encryption engine, and store the encrypted data in a memory of the destination. Other embodiments are described and claimed.
