  • Patent number: 11835937
    Abstract: A data distribution program causes a server apparatus to execute a process of distributing project data to a terminal apparatus that writes the project data to a device among a plurality of devices included in an apparatus. The data distribution program causes the server apparatus to execute: receiving a distribution request for the project data from the terminal apparatus; identifying a related device that is another device constituting one apparatus together with the device to which the project data designated in the distribution request is written; identifying the related device that requires update of project data based on a version of the project data designated in the distribution request and a version of the project data written in the related device; and transmitting, to the terminal apparatus, the project data designated in the distribution request and the project data to be written to the related device identified.

  • Patent number: 11822663
    Abstract: Systems and methods for verifying firmware before it is loaded to a memory device are presented herein. An amount of available memory remaining in a memory device after firmware is written to the memory device is determined, and padding data having a size equal to the determined amount of remaining available memory is generated and appended to the firmware (e.g., the firmware is padded with the padding data). In this way, there is no room for malicious code or a malicious version of the firmware in the memory device. A processing device may determine a verification value of the padded firmware and store the verification value. The verification value may be a cryptographic hash of the padded firmware or a cryptographic signature of the padded firmware. The padded firmware is then written to the memory device. The firmware may be read from the memory device and verified using the verification value.

  • Patent number: 11822664
    Abstract: Techniques are disclosed relating to securing computing devices during boot. In various embodiments, a secure circuit of a computing device generates for a public key pair and signs, using a private key of the public key pair, configuration settings for an operating system of the computing device. A bootloader of the computing device receives a certificate for the public key pair from a certificate authority and initiates a boot sequence to load the operating system. The boot sequence includes the bootloader verifying the signed configuration settings using a public key included in the certificate and the public key pair. In some embodiments, the secure circuit cryptographically protects the private key based on a passcode of a user, the passcode being usable by the user to authenticate to the computing device.

  • Patent number: 11806784
    Abstract: A rapid material development process for a powder bed fusion additive manufacturing (PBF AM) process generally utilizes a computational fluid dynamics (CFD) simulation to facilitate selection of a simulated parameter set, which can then be used in a design of experiments (DOE) to generate an orthogonal parameter space to predict an ideal parameter set. The orthogonal parameter space defined by the DOE can then be used to generate a multitude of reduced volume build samples using PBF AM with varying laser or electron beam parameters and/or feedstock chemistries. The reduced volume build samples are mechanically characterized using high throughput techniques and analyzed to provide an optimal parameter set for a 3D article or a validation sample, which provides an increased understanding of the parameters and their independent and confounding effects on defects and microstructure.

  • Patent number: 11770246
    Abstract: A multi-processor device includes a first processor implemented with a secured key derivation and storage component and a second processor implemented without a secured key derivation and storage component. In operation, the second processor is configured to execute an initial boot process by loading a limited functionality boot image when the multi-processor device is powered on. During the execution of the initial boot process, the second processor provisions a secure storage container to hold a key material and sends a request to the first processor for a key material. In response, the second processor receives a key material derived at the first processor. The second processor then stores the key material in a volatile memory portion of the secure storage container. The second processor executes a main boot process only after erasing instances of the key material temporarily stored outside of the secure storage container.
