  • Publication number: 20240126691
    Abstract: Technologies for cryptographic separation of MMIO operations with an accelerator device include a computing device having a processor and an accelerator. The processor establishes a trusted execution environment. The accelerator determines, based on a target memory address, a first memory address range associated with the memory-mapped I/O transaction, generates a second authentication tag using a first cryptographic key from a set of cryptographic keys, wherein the first key is uniquely associated with the first memory address range. An accelerator validator determines whether the first authentication tag matches the second authentication tag, and a memory mapper commits the memory-mapped I/O transaction in response to a determination that the first authentication tag matches the second authentication tag. Other embodiments are described and claimed.

  • Publication number: 20220027288
    Abstract: Technologies for secure data transfer include a computing device having a processor, an accelerator, and a security engine, such as a direct memory access (DMA) engine or a memory-mapped I/O (MMIO) engine. The computing device initializes the security engine with an initialization vector and a secret key. During initialization, the security engine pre-fills block cipher pipelines and pre-computes hash subkeys. After initialization, the processor initiates a data transfer, such as a DMA transaction or an MMIO request, between the processor and the accelerator. The security engine performs an authenticated cryptographic operation for the data transfer operation. The authenticated cryptographic operation may be AES-GCM authenticated encryption or authenticated decryption. The security engine may perform encryption or decryption using multiple block cipher pipelines. The security engine may calculate an authentication tag using multiple Galois field multipliers. Other embodiments are described and claimed.
