    摘要： In a pre-operating system environment on a device prior to loading and running an operating system on the device, a policy identifying configuration settings for the operating system is obtained. The operating system itself is prevented from changing this policy, but the policy can be changed under certain circumstances by components of the pre-operating system environment. The policy is compared to configuration values used by the operating system, and the operating system is allowed to boot with the configuration values if the configuration values satisfy the policy. However, if the configuration values do not satisfy the policy, then a responsive action is taken.

    摘要： An event log can comprise, not only entries associated with components instantiated since a most recent power on of a computing device, but also entries of components instantiated prior to that power on, such as components that were instantiated, and represent, a state of the computing device prior to hibernation that has now been resumed. Upon hibernation, the current values of the Platform Configuration Registers (PCRs) of a Trusted Platform Module (trusted execution environment), as well as a quote of those current values, and a current value of a monotonic counter of the trusted execution environment can be logged. The monotonic counter can be incremented at each power on to track successive generations of the computing device and to guard against an intervening, not-logged generation. A subsequent parsing of the event log can verify the prior generational entries with reference to the PCR values in the log that are associated with those generations.

    摘要： Booting a computing device includes executing one or more firmware components followed by a boot loader component. A protection component for the computing device, such as an anti-malware program, is identified and executed as an initial component after executing the boot loader component. One or more boot components are also executed, these one or more boot components including only boot components that have been approved by the protection component. A list of boot components that have been previously approved by the protection component can also be maintained in a tamper-proof manner.

    摘要： One or more techniques and/or systems are provided for provisioning encrypted key blobs and client certificates. That is, a trusted execution environment on a first machine may provide a key service provider with a cryptographic encryption key. The key service provider may encrypt a key blob using the cryptographic encryption key and/or wrap the encrypted key blob with one or more policies, such as a platform policy. The key service provider may provision the encrypted key blob to a client on the first machine. The client may submit the encrypted key blob to the trusted execution environment for validation so that the client may perform key actions, such as sign an email or encrypt data. Because the key blob may be specific to a particular trusted execution environment and/or machine, the key service provider may re-wrap the key blob if the client “roams” to a second machine.
