  • Patent number: 11074348
    Abstract: A set of root keys is loaded as a first part of a secure boot process of a secure system. a first trusted key from a set of trusted keys is verified using a first root key from the set of root keys as a second part of the secure boot process. The set of trusted keys is loaded when an affirmative verification for a subset of trusted keys is received. The subset of trusted keys includes the first trusted key. As a third part of the secure boot process, an immutable portion of a file is validated using the first trusted key. As a fourth part of the secure boot process, the file is loaded when each portion of the file is successfully validated. The first, second, third, and fourth parts of the secure boot process occur before an integrity management configuration takes over the secure boot process.

    Abstract: A surgical instrument (1000) includes an end effector assembly (200) including first and second grasping components (210, 220) each defining a tissue-contacting portion (214, 218, 224, 228). One or both of the first or second grasping components (210, 220) is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions (214, 218, 224, 228) cooperate to define a grasping area therebetween. One or both of the first or second grasping components (210, 220) is configured to apply energy from the tissue-contacting portion (214, 218, 224, 228) thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion (214, 224) of the first grasping component (210) defines a first opening (219) therethrough. The first opening (219) is disposed within the grasping area and in communication with a first lumen (118) defined at least partially through the first grasping component (210).

  • Patent number: 10763338
    Abstract: The present disclosure describes a silicide formation process which employs the formation of an amorphous layer in the SiGe S/D region via an application of a substrate bias voltage during a metal deposition process. For example, the method includes a substrate with a gate structure disposed thereon and a source/drain region adjacent to the gate structure. A dielectric is formed over the gate structure and the source-drain region. A contact opening is formed in the dielectric to expose a portion of the gate structure and a portion of the source/drain region. An amorphous layer is formed in the exposed portion of the source/drain region with a thickness and a composition which is based on an adjustable bias voltage applied to the substrate. Further, an anneal is performed to form a silicide on the source/drain region.

  • Patent number: 10685122
    Abstract: A computer-implemented method for protecting a kernel for secure boot of an operating system includes preparing a kernel component with a signature for a secure boot. A processing unit modifies a machine owner key (MOK) file to include a trusted certificate. The MOK is separate from the kernel file. The processing unit validates the kernel component using a modified Grub file, a modified Shim file, and the MOK, and executes a secure boot using the validated kernel component. The kernel is unchanged by the secure boot process. The kernel component that is protected may be either a program executable (PE) file or a non-PE file.
