    Abstract: Technologies for hybrid acceleration of code include a computing device (100) having a processor (120), a field-programmable gate array (FPGA) (130), and an application-specific integrated circuit (ASIC) (132). The computing device (100) offloads a service request, such as a cryptographic request or a packet processing request, to the FPGA (130). The FPGA (130) performs one or more algorithmic tasks of an algorithm to perform the service request. The FPGA (130) determines one or more primitive tasks associated with an algorithm task and encapsulates each primitive task in a buffer that is accessible by the ASIC (132). The ASIC (132) performs the primitive tasks in response to encapsulation in the buffer, and the FPGA (130) returns results of the algorithm. The primitive operations may include cryptographic primitives such as modular exponentiation, modular multiplicative inverse, and modular multiplication. The results may be returned to the processor (120) or a network interface controller of the computing device (100).

    Abstract: Technologies for key management of internet-of-things (IoT) devices include an IoT device, an authority center server, and a group management server. The IoT device is configured to authenticate with an authority center server via an offline communication channel, receive a group member private key as a function of the authentication with the authority center server, and authenticate with a group management server via a secure online communication channel using the group member private key. The IoT device is further configured to receive a group shared key as a function of the authentication with the group management server, encrypt secret data with the group shared key, and transmit the encrypted secret data to the group management server. Other embodiments are described herein.

    Abstract: An apparatus and method to implement shared virtual memory in a trust zone. For example, one embodiment of a processor comprises: a plurality of cores; a memory controller coupled to the plurality of cores to establish a first private memory region in a system memory using a first key associated with a first trust domain of a first guest; an input/output memory management unit (IOMMU) coupled to the memory controller, the IOMMU to receive a memory access request by an input/output (IO) device, the memory access request comprising a first address space identifier and a guest virtual address (GVA), the IOMMU to access an entry in a first translation table using at least the first address space identifier to determine that the memory access request is directed to the first private memory region which is not directly accessible to the IOMMU, the IOMMU to generate an address translation request associated with the memory access request, wherein based on the address translation request, a virtual machine monitor (VMM) running on one or more of the plurality of cores is to initiate a secure transaction sequence with trust domain manager to cause a secure entry into the first trust domain to translate the GVA to a physical address based on the address space identifier, the IOMMU to receive the physical address from the VMM and to use the physical address to perform the requested memory access on behalf of the IO device.

    Abstract: A cryptographic data item utilized to derive a first cryptographic key employed by a first memory controller for implementing a first cryptographically protected execution environment for storing memory pages associated with a virtual machine may be received from a first host system via a first secure communication channel. The cryptographic data item may be transmitted to a second host system via a second secure communication channel for implementing a second cryptographically protected environment on the second host system. The first host system may be caused to migrate the memory pages of the virtual machine via an unsecured communication channel to the second host system for storing in the second cryptographically protected execution environment.

    Abstract: Methods and apparatus for customers key protection for cloud native deployments. Compute resources for a compute platform comprising platform hardware including one or more processors are allocated to one or more customers that use the compute resources to execute applications and/or services used to perform customer workloads. The compute platform includes a per-part device key that is used to generate hardware protected key used by the applications and services. Mechanisms are provided to ensure hardware protected keys can only be accessed by associated customers and/or customer applications and services, while preventing other customers and/or applications and services from accessing the hardware protected keys. The hardware protected keys include keys employing various forms of RSA and ECC Wrapped Private Keys (WPKs) including RSA WPKs, RSA Chinese Remainder Theorem CRT WPK and ECC WPKs.
