    摘要： Described is maintaining cached hash values for files in association with state data for each file that represents the state of that file's contents at the time of hashing. For example, in a journaling file system, the state data may comprise the update sequence number of the file in the journal and a journal identifier for that journal instance. A request for a hash value for a file is processed by determining whether a cached hash value is maintained for that file. If so, and the associated maintained state data matches current state data for the file, the file contents are unchanged since the last hash computation, whereby the cached hash value is returned in response to the request. Otherwise, a new hash value is computed for the file and returned, and cached for future use. Multiple types of hashes may be cached for a given file.

    摘要： A computing device has a user desktop on which a relatively less-secure user application is executed and a secure desktop elevated from the user desktop on which a relatively more-secure secure application is executed upon a request thereto from the user application. To securely collect information from a user at the computer device with regard to the secure application at the secure desktop, an access interface is securely executed on the secure desktop and is visually presented in conjunction with the requesting user application of the user desktop such that the access interface is visually coupled to the requesting user application and is visually perceived by the user along with such requesting user application.

    摘要： Security elevation techniques are described. In an implementation, a request is received for additional security access beyond that which is currently specified for a program. An identity that describes the program is checked with a plurality of conditions. The security level is automatically elevated to grant the additional security access when the identity corresponds to one of the conditions that indicates that the security level is to be automatically elevated.

    摘要： An application development system for smart cards includes a computer system having a client development interface (CDI), a smart card having a smart card development interface (SCDI) and application program interface (API) functionality within the smart card operating system. The SCDI interfaces remote procedure calls from the CDI, thereby allowing API functionality to be called upon within the smart card operating system. In operation, the SCDI receives remote procedure calls (RPC) from the computer system and selectively invokes APIs associated with smart card operating system, thereby enabling the smart card to carry out specific functional tasks.
