    摘要： An efficient protocol for retrieving cryptographic evidence may be selected by evaluating a local policy and a number of relevant factors. Furthermore, updated cryptographic evidence may be prefetched during a time period in which there is a low volume of requests for cryptographic evidence. This low volume time period may be defined, approximately, as an overlapping window in which both a first cryptographic evidence publication and a second cryptographic evidence publication are valid.

    摘要： Implementations are described and claimed herein to enable credential roaming among a plurality of different computing devices. An exemplary system may include an event handler to receive event notifications such as, e.g., a client logon. The event handler may invoke a management service in response to receiving an event notification. The management service may include a synchronizing module to synchronize a user's credentials with a remote directory service, such as, e.g., Active Directory, so that the user's credentials are available from any of a number of different computing devices.

    摘要： Methods and apparatuses are provided for use with smartcards or other like shared computing resources. One or more root certificates are stored on a smartcard. The root certificates can be selectively copied to a certificate store or other like mechanism of an operatively coupled computing or like device and available to support certificate and other trust related processes of the device. When the smartcard is no longer operatively available to the device, the root certificates are no longer available to support such certificate and other trust related processes of the device.

    摘要： An update process is used to update root certificates in a root certificate store of a client computer, maintaining the integrity of the existing root certificates as well as any new root certificates. In accordance with certain aspects, the integrity of a certificate trust list identifying one or more root certificates is verified. The root certificate store of the client computer is modified in accordance with the certificate trust list if the integrity of the certificate trust list is verified.

    摘要： Systems and methods for validating integrity of an executable file are described. In one aspect, multiple partial image hashes are generated, the combination of which represent a digest of an entire executable file. Subsequent to loading the executable file on a computing device, a request to page a portion of the executable file into memory for execution is intercepted. Responsive to intercepting the request, and prior to paging the portion into memory for execution, a validation hash of the portion is computed. The validation hash is compared to a partial hash of the multiple partial image hashes to determine code integrity of the portion. The partial hash represents a same code segment as the portion.
