Abstract: The techniques disclosed herein enable a system to configure a confidential virtual resource unit by provisioning a security component to a tenant's virtual resource unit. The system creates multiple different virtual trust layers within the confidential virtual resource unit. This creation effectively defines security boundaries between the virtual trust layers. The virtual trust layers are associated with different privileges, such that a higher privileged virtual trust layer is provided with more privileges compared to a lower privileged virtual trust layer. In one example, a lower privileged virtual trust layer may include basic virtual resource components (e.g., drivers, applications, processes, functions, workloads executing within a guest operating system) and a higher privileged virtual trust layer is the location to which a virtual security component is provisioned by the system.

Abstract: The invention relates to a curable coating composition comprising: at least one acrylate functional oligomer; at least one furan-based reactive diluent; and at least one photoinitiator. The invention also relates to methods of making and using the curable coating composition of the invention. The invention also relates to a method for improving the hardness, abrasion resistance, and/or durability of an object or a substrate.

Abstract: A flow battery system has an electrolyte storage tank, a flow battery, and a box-type flow battery system. A circular pipe I and a circular pipe II are provided in the electrolyte storage tank; the circular pipe II is communicated with an electrolyte return opening; the circular pipe I is communicated with an electrolyte delivery outlet; the annular perimeter of the circular pipe I is not equal to the annular perimeter of the circular pipe II. The multi-layer circular pipe structure in the storage tank reduces the flowing dead zone of electrolyte in the storage tank. Moreover, The reduction in the longitudinal distance between the electrolyte delivery outlet and the electrolyte return opening also reduced the problem of SOC lag so that the SOC monitoring accuracy of the flow battery is improved.

Abstract: A flow battery has a control system and a control method to control the operation of the flow battery. The control method includes disposing an SOC detection device respectively at a positive electrolyte outlet and a negative electrolyte outlet of a cell stack; obtaining, by the SOC detection devices, SOCs at the electrolyte outlets of the cell stack under an initial state of the flow battery; at every preset time, acquiring the volume of electrolyte in the positive electrolyte storage tank, the volume of electrolyte in the negative electrolyte storage tank, the volume of the electrolyte flowing into the positive electrolyte storage tank, and the volume of the electrolyte flowing into the negative electrolyte storage tank, and meanwhile, obtaining, by the SOC detection devices, SOCs at the electrolyte outlets of the cell stack; and obtaining SOC of the flow battery.

Abstract: Techniques are described herein that are capable of establishing system integrity using attestation for a virtual trusted platform module (vTPM). For instance, an endorsement key certificate, including an endorsement key associated with the vTPM, may be signed to issue the endorsement key certificate to the vTPM. The endorsement key certificate may be used to establish a chain of trust with regard to the vTPM. For instance, the endorsement key certificate may be used to attest the vTPM (and measurements provided by the vTPM).

Abstract: A facility for booting a virtual machine hosted on a host is described. In one example facility, the facility boots the virtual machine in accordance with a policy instance associated with the virtual machine. As part of the booting, the facility extracts information needed to complete the booting from a virtual trusted platform module associated with the virtual machine, the extraction based upon the policy instance associated with the virtual machine. At the completion of the booting, the facility copies contents of a policy instance associated with the host into the policy instance associated with the virtual machine.

Abstract: Described is the backup and/or restore of virtual disks In general, metadata is backed up for restoring a virtual disk. To restore the disk, a physical disk is created, with the virtual disk the created on a partition of the physical disk. Backup and restore is described for nested virtual disks, including for block level restore. Further described is backing up of critical virtual disks and their containers, and virtual disk backup with respect to basic disks and dynamic volumes.
