摘要： In a cloud computing environment, a production server virtualization stack is minimized to present fewer security vulnerabilities to malicious software running within a guest virtual machine. The minimal virtualization stack includes support for those virtual devices necessary for the operation of a guest operating system, with the code base of those virtual devices further reduced. Further, a dedicated, isolated boot server provides functionality to securely boot a guest operating system. The boot server is isolated through use of an attestation protocol, by which the boot server presents a secret to a network switch to attest that the boot server is operating in a clean mode. The attestation protocol may further employ a secure co-processor to seal the secret, so that it is only accessible when the boot server is operating in the clean mode.

摘要： Disclosed is a trusted language runtime (TLR) architecture that provides abstractions for developing a runtime for executing trusted applications or portions thereof securely on a mobile device (e.g., a smartphone). TLR offers at least two abstractions to mobile developers: a trustbox and a trustlet. The trustbox is a runtime environment that offers code and data integrity, and confidentiality. Code and data running inside a trustbox cannot be read or modified by any code running outside the trustbox. A trustlet is the code portion of an application that runs inside a trustbox. With TLR, programmers can write applications in .NET and specify which parts of the application handle sensitive data, and thus, run inside the trustbox. With the TLR, the developer places these parts in a trustlet class, and the TLR provides all support needed to run the parts in the trustbox.

摘要： Technology is described for protection of virtual machines executing on a host device having host processors and host memory. The system can include a hypervisor configured to enable the virtual machines to execute concurrently on the host device. An emancipated partition can be provided with a communication channel to the hypervisor. A primary partition can be configured to interface with the emancipated partition through the communication channel via the hypervisor. In addition, an emancipated memory space and virtual register state for the emancipated partition can be protected from direct access by the primary partition.

摘要： A hypervisor provides a snapshot protocol that generates a verifiable snapshot of a target machine. The verifiable snapshot includes a snapshot and a signed quote. In one implementation, a challenger requests a snapshot of the target machine. In response to the snapshot request, the hypervisor initiates Copy-on-Write (CoW) protection for the target machine. The hypervisor snapshots and hashes each of the memory pages and the virtual central processing unit (CPU) of the target machine. The hypervisor generates a composite hash by merging all individual memory page hashes and the CPU state hash. The hypervisor requests a quote including integrity indicators of all trusted components and the composite hash. The quote uses a cryptographic signature from a trusted platform module, which ensures that any compromise of the integrity of the snapshot is detectable. The snapshot and signed quote are returned to the challenger for verification.

摘要： In accordance with certain aspects, data is received from a calling program. Ciphertext that includes the data is generated, using public key encryption, in a manner that allows the data to be obtained from the ciphertext only if one or more conditions are satisfied. In accordance with another aspect, a bit string is received from a calling program. Data in the bit string is decrypted using public key decryption and returned to the calling program only if one or more conditions included in the bit string are satisfied.

摘要： A single application can be executed across multiple execution environments in an efficient manner if at least a relevant portion of the virtual memory assigned to the application was equally accessible by each of the multiple execution environments. A request by a process in one execution environment can, thereby, be directed to an operating system, or other core software, in another execution environment and can be made by a shadow of the requesting process in the same manner as the original request was made by the requesting process itself. Because of the memory invariance between the execution environments, the results of the request will be equally accessible to the original requesting process even though the underlying software that responded to the request may be executing in a different execution environment. A similar thread invariance can be maintained to provide for accurate translation of requests between execution environments.
摘要翻译： 如果分配给应用的虚拟存储器的至少相关部分可以被多个执行环境中的每个执行环境同等地访问，则可以以有效的方式在多个执行环境中执行单个应用。 一个执行环境中的进程的请求可以由此被引导到另一执行环境中的操作系统或其他核心软件，并且可以以与原始请求相同的方式通过请求进程的阴影来进行 通过请求过程本身。 由于执行环境之间的内存不变性，即使响应请求的底层软件可能在不同的执行环境中执行，原始请求进程的请求结果也可以同样访问。 可以维护类似的线程不变性，以便在执行环境之间提供精确的请求转换。

摘要： Systems and methods provide multiple partitions hosted on an isolation technology such as a hypervisor where at least one of the partitions, a local secure service partition (LSSP), provides security services to other partitions. The service partitions (LSSPs) host those high assurance services that require strict security isolation, where the service can be shared across partitions and accessed even when the user is not connected to a network. The LSSP also can certify the results of any computation using a key signed by a TPM attestation identity key (AIK), or other key held securely by the hypervisor or a service partition. The LSSPs may be configured to provide trusted audit logs, trusted security scans, trusted cryptographic services, trusted compilation and testing, trusted logon services, and the like.

摘要： In accordance with certain aspects, data is received and a digital signature is generated and output. The digital signature can be a digital signature of the data and one or more conditions that are to be satisfied in order for the data to be revealed, or a digital signature over data generated using a private key associated with a bound key that is bound to one or more processors.
