摘要： In some embodiments, a processor-based system may include at least one processor, at least one memory coupled to the at least one processor, a boot block stored at a first memory location, a capsule update stored at a second memory location, a startup authenticated code module to ensure the integrity of the boot block upon a restart of the processor-based system, code which is executable by the processor-based system to cause the processor-based system to validate the boot block with the startup authenticated code module upon the restart of the processor-based system, and, if the boot block is successfully validated, to validate the capsule update for the processor-based system with the startup authenticated code module. Other embodiments are disclosed and claimed.

摘要： In some embodiments, the invention involves using a policy engine during boot, in the driver execution environment (DXE) phases to authenticate that drivers and executable images to be loaded are authenticated. Images to be authenticated include the operating system (OS) loader. The policy engine utilizes a certificate database to hold valid certificates for third party images, according to platform policy. Images that are not authenticated are not loaded at boot time. Other embodiments are described and claimed.

摘要： Embodiments provide a system including a first host computing device that includes a first virtual machine (VM) and a first application. The system also includes a second host computing device including a virtualization software layer, a second VM, and an auto-discovery service at least partially instantiated within the virtualization software layer. The auto-discovery service is configured to receive a message and an auto-discovery packet from a second application executing on the second VM. The auto-discovery service inserts an option into the auto-discovery packet, and transmits the auto-discovery packet to the first application. The option in the auto-discovery packet includes the message received from the second application.
