Abstract

See full text

Technologies for authenticity assurance for I/O data include a computing device with a cryptographic engine and one or more I/O controllers. A metadata producer of the computing device performs an authenticated encryption operation on I/O data to generate encrypted I/O data and an authentication tag. The metadata producer stores the encrypted I/O data in a DMA buffer and the authentication tag in an authentication tag queue. A metadata consumer decrypts the encrypted I/O data from the DMA buffer and determines whether the encrypted I/O data is authentic using the authentication tag from the authentication tag queue. For input, the metadata producer may be embodied as the cryptographic engine and the metadata consumer may be embodied as a trusted software component. For output, the metadata producer may be embodied as the trusted software component and the metadata consumer may be embodied as the cryptographic engine. Other embodiments are described and claimed.
