摘要： Examples set out herein provide a method comprising using first cryptographic key data specific to a computing device to verify a package of machine readable instructions to run on the computing device. The verified package may be executed to generate a random number using a true random number generator of the computing device, and to store the generated random number. Second cryptographic key data may be generated by a pseudorandom number generator of the computing device based on a seed comprising a combination of the random number as a first seed portion and a second seed portion. A portion of the second cryptographic key data may be sent to a certifying authority. The method may further comprising receiving a certification value based on the sent portion of the second cryptographic key data from the certifying authority and storing the certification value.

摘要： In a virtualized computer system in which a plurality of virtual machines run on a platform that includes a hardware graphics processing unit (‘GPU’), provision is made for dynamically assigning the GPU to a selected one of the virtual machines. To this end, each virtual machine comprises, in addition to a guest operating system, a virtual bus with a hot-pluggable slot, and a virtual first configuration-management component responsive to events relevant to the hot-pluggable slot to interact with a second configuration-management component provided as part of the guest operating system of the virtual machine. To assign the GPU to a selected virtual machine, an emulated slot insertion event is generated in respect of the virtual hot-pluggable slot of the selected virtual machine thereby causing the first configuration-management component of that machine to trigger the guest operating system of the first virtual machine to operatively engage with the GPU.

摘要： In some examples, a privileged domain includes a function of a Basic Input/Output System (BIOS). A request to access the function of the BIOS is routed to the privileged domain. The privileged domain determines whether to execute the function based on identifying at least one selected from among a source of the request and a context of the request.

摘要： A set of data is provided to an application executed in an environment within which the application is restricted from making its output available outside the environment. An operation performed on the set of data by the application is inspected. A determination of whether an output of the application is satisfactory is reached based on the inspection. If the output is determined satisfactory, the output of the application is made available outside the environment.

摘要： To provide a secure service to an application virtual machine running in a first domain of a virtualized computing platform, a second domain is arranged to run a corresponding service driver exclusively for the application virtual machine. As part of the secure service, the service driver effects a key-based cryptographic operation; to do so, the service driver has to obtain the appropriate key from a key manager. The key manager is arranged to store the key and to release it to the service driver only upon receiving evidence of its identity and being satisfied of compliance with release policies associated with the key. These policies include receipt of valid integrity metrics, signed by trusted-device functionality of the virtualized computing platform, for the service driver and the code on which it depends.
摘要翻译：为了向在虚拟化计算平台的第一域中运行的应用虚拟机提供安全服务，第二域被安排为专用于应用虚拟机运行相应的服务驱动器。作为安全服务的一部分，服务驱动程序实现了基于密钥的加密操作; 要这样做，服务驱动程序必须从密钥管理器获取适当的密钥。密钥管理器被安排为存储密钥，并且仅在接收到其身份的证据并且满足与密钥相关的释放策略的满足时将其释放给服务驱动器。这些策略包括为服务驱动程序及其所依赖的代码接收由虚拟化计算平台的可信设备功能签名的有效完整性度量。
