Technologies for secure I/O data transfer with an accelerator device include a computing device having a processor and an accelerator. The processor establishes a trusted execution environment. The trusted execution environment may generate an authentication tag based on a memory-mapped I/O transaction, write the authentication tag to a register of the accelerator, and dispatch the transaction to the accelerator. The accelerator performs a cryptographic operation associated with the transaction, generates an authentication tag based on the transaction, and compares the generated authentication tag to the authentication tag received from the trusted execution environment. The accelerator device may initialize an authentication tag in response to a command from the trusted execution environment, transfer data between host memory and accelerator memory, perform a cryptographic operation in response to transferring the data, and update the authentication tag in response to transferrin the data. Other embodiments are described and claimed.

Technologies for secure device configuration and management include a computing device having an I/O device. A trusted agent of the computing device is trusted by a virtual machine monitor of the computing device. The trusted agent securely commands the I/O device to enter a trusted I/O mode, securely commands the I/O device to set a global lock on configuration registers, receives configuration data from the I/O device, and provides the configuration data to a trusted execution environment. In the trusted I/O mode, the I/O device rejects a configuration command if a configuration register associated with the configuration command is locked and the configuration command is not received from the trusted agent. The trusted agent may provide attestation information to the trusted execution environment. The trusted execution environment may verify the configuration data and the attestation information. Other embodiments are described and claimed.
