Abstract: Technologies for optimization of a memory controller include a computing device having a memory manager, a memory trainer, and a platform firmware. The memory manager reserves a space in memory of the computing device that is inaccessible to an operating system of the computing device. The memory trainer utilizes the reserved space to perform a memory training to determine configuration settings of the memory controller. After the configuration settings of the memory controller have been determined, the platform firmware configures the memory controller with the determined configuration settings.

Abstract: A pre-boot initialization technique for a computing system allows for encrypting both a manufacturer and original equipment manufacturer firmware routines, as well as handing off data between the manufacturer and original equipment manufacturer firmware routines encrypted with a key provisioned in field programmable fuses with an original equipment manufacturer key. By encrypting the firmware routines and handoff data, security of the pre-boot initialization process is enhanced. Original equipment manufacturer updatable product data may also be encrypted with the original equipment manufacturer key. Additional security may be provided by using trusted input/output capabilities of a trusted execution environment to display information to and receive information from a user. Furthermore, multiple secure phases of configuration may be achieved using wireless credentials exchange components.

Abstract: Technologies for performing a secure firmware update include a compute device that includes a memory device to store firmware update payload, one or more devices that have direct memory access (DMA) to the memory, a DMA remap module, and a firmware update module. The DMA remap module is to create a memory isolation domain for each of the one or more devices. Each memory isolation domain comprises a physical address space in the memory that is mutually exclusive to the physical address spaces of the other memory isolation domains. The firmware update module is to (i) analyze the firmware update payload to identify one or more of the devices associated with the firmware update payload and (ii) move the firmware update payload to the memory isolation domains of each associated device to enable secure transmission of the firmware update payload to the associated devices.

Abstract: A point-of-sale device (“POS”) is described to include a secure transaction tunnel generator (“STG”). The STG may generate secure tunnels between peripherals attached to the POS and remote network resources. The secure tunnel may be generated using a trusted execution environment (“TEE”) of the POS. The STG may be alerted to the need to generate the secure tunnel based on an alert from the peripheral. The STG may execute under a protected environment and may generate two ends of a secure transaction tunnel using the TEE. The STG may also check the peripheral against whitelists and/or blacklists to determine whether the peripheral is allowed or not disallowed to participate in secure transactions. By generating the secure tunnel, the STG may facilitate performance of transactions in such a way that sensitive information is not available to unsecured processes in the POS. Other embodiments may be described and/or claimed.

Abstract: A method for booting a data processing system (DPS) involves, during a boot process of the DPS, using a preliminary bootcode module from a low-speed nonvolatile memory (NVM) in the DPS to load a main bootcode module from a high-speed NVM in the DPS into a volatile random access memory (RAM) in the DPS, wherein the high-speed NVM supports a read speed that is faster than a maximum read speed of the low-speed NVM. The method also involves, during the boot process, after loading the main bootcode module from the high-speed NVM into the RAM, using the main bootcode module to boot the DPS to an operating system (OS). The method may also involve using the preliminary bootcode module to automatically determine whether the main bootcode module from the high-speed NVM has good integrity. Other embodiments are described and claimed.

Abstract: This disclosure is directed to firmware-related event notification. A device may comprise an operating system (OS) configured to operate on a platform. During initialization of the device a firmware module in the platform may load at least one globally unique identifier (GUID) into a firmware configuration table. When the platform notifies the OS, the firmware module may load at least one GUID into a platform notification table and may set a platform notification bit in a platform notification table status field. Upon detecting the notification, an OS management module may establish a source of the notification by querying the platform notification table. The platform notification bit may cause the OS management module to compare GUIDs in the platform notification table and the firmware configuration table. Services may be called based on any matching GUIDs. If no GUIDs match, the services may be called based on firmware variables in the device.

Abstract: Disclosed herein are distributed ledger systems and methods for efficiently creating and updating a query optimized distributed ledger.

Abstract: The present disclosure is directed to secure sensor data transport and processing. End-to-end security may prevent attackers from altering data during the sensor-based security procedure. For example, following sensor data capture execution in a device may be temporarily suspended. During the suspension of execution, sensor interface circuitry in the device may copy the sensor data from a memory location associated with the sensor to a trusted execution environment (TEE) within the device. The TEE may provide a secure location in which the sensor data may be processed and a determination may be made as to whether to grant access to the secure resources. The TEE may comprise, for example, match circuitry to compare the sensor data to previously captured sensor data for users that are allowed to access the secured resources and output circuitry to grant access to the secured resources or to perform activities associated with a security exception.

Abstract: A dynamic firmware module loader loads one of a plurality of a firmware contexts or modules as needed in a containerized environment for secure isolated execution. The modules, called applets, may be loaded and unloaded in a firmware context. The loader may use a hardware inter process communication channel (IPC) to communicate with the secure engine. The modules may be designed to implement specific features desired by basic input/output system vendors, without the use of a system management mode. Designed modules may provide necessary storage and I/O access driver capabilities to be run in trusted execution environment containers.

Abstract: The present application is directed to access isolation for multi-operating system devices. In general, a device may be configured using firmware to accommodate more than one operating system (OS) operating concurrently on the device or to transition from one OS to another. An access isolation module (AIM) in the firmware may determine a device equipment configuration and may partition the equipment for use by multiple operating systems. The AIM may disable OS-based equipment sensing and may allocate at least a portion of the equipment to each OS using customized tables. When transitioning between operating systems, the AIM may help to ensure that information from one OS is not accessible to others. For example, the AIM may detect when a foreground OS is to be replaced by a background OS, and may protect (e.g., lockout or encrypt) the files of the foreground OS prior to the background OS becoming active.

Abstract: Technologies for privacy-safe security policy evaluation include a cloud analytics server, a trusted data access mediator (TDAM) device, and one or more client devices. The cloud analytics server curries a security policy function to generate a privacy-safe curried function set. The cloud analytics server requests parameter data from the TDAM device, which collects the parameter data, identifies sensitive parameter data, encrypts the sensitive parameter data, and transmits the encrypted sensitive parameter data to the cloud analytics server. The cloud analytics server evaluates one or more curried functions using non-sensitive parameters to generate one or more sensitive functions that each take a sensitive parameter. The cloud analytics server transmits the sensitive functions and the encrypted sensitive parameters to a client computing device, which decrypts the encrypted sensitive parameters and evaluates the sensitive functions with the sensitive parameters to return a security policy.
