    摘要: A distributed computer system has a number of computers coupled thereto at distinct nodes. The computer at each node of the distributed system has a trusted computing base that includes an authentication agent for authenticating requests received from principals at other nodes in the system. Requests are transmitted to servers as messages that include a first identifier provided by the requester and a second identifier provided by the authentication agent of the requester node. Each server process is provided with a local cache of authentication data that identifies requesters whose previous request messages have been authenticated. When a request is received, the server checks the request's first and second identifiers against the entries in its local cache. If there is a match, then the request is known to be authentic. Otherwise, the server node's authentication agent is called to obtain authentication credentials from the requester's node to authenticate the request message. The principal identifier of the requester and the received credentials are stored in a local cache by the server node's authentication agent. The server process also stores a record in its local cache indicating that request messages from the specified requester are known to be authentic, thereby expediting the process of authenticating received requests.

    摘要: Systems and methods are provided for resource access control in computer systems. Our approach includes new techniques for composing and authenticating principals in an access control system. Our principals may comprise information that identifies the role of the user of a computer system, the mechanism by which the user was authenticated, and program execution history. Thus, when a principal makes a request, access control determinations can be made based on the principal's identity. Access control lists may provide patterns that are used to recognize principals, thereby ensuring a level of security without enumerating precise identifiers for all of the possible principles that may request a particular resource.

    摘要: A lifting and shaping system for a bra is disclosed. The system uses lift platforms shaped to fit into the cups of the bra and formed from thin material such as plastic. The lift platforms are attached to the bra toward the center of the bra. Connectors having one end attached to the lift platform and the other end attached to a slide on the shoulder strap adjust the lift of the lift platform when the slide is moved. Flexible shaping members distribute the lift of the lift platforms and maintain the natural shape of the breasts as they are lifted. Smoothing shields ease the movement of the lift platforms and connectors within the cloth confines of the breast cups. The flexible shaping members may also perform some of the functions of a smoothing shield.

    摘要: Methods and systems are provided for a cancellation server maintaining a database of identifiers of cryptographic puzzles. A cryptographic puzzle is created from a unique identifier and a timestamp, and is attached to an electronic mail message, along with the puzzle's solution. The recipient verifies that the solution is correct and that the timestamp is current, and further queries the cancellation server with the puzzle identifier. If the identifier does not exist in the database, then the recipient knows the received message is legitimate. If the identifier already appears in the database, the received message can be automatically removed from the recipient's computer.

    摘要: Flash memory is managed utilizing memory management data structures residing in volatile memory of a flash memory device. The memory management data structures are created and updated each time power is supplied to the memory device. During write operations to the flash memory, specific locations in the flash memory are updated to reflect the current status of the flash memory. When power is interrupted, the memory management data structures are recreated upon reapplication of power. The flash memory is scanned and the information obtained from the specific locations in the flash memory is utilized to construct the memory management data structures. No bad block tables are required. Flash memory is managed to provide relatively good random write performance and to accommodate power interruptions. Applications include the use of flash memory for general purpose computing and devices in which power can fail at any time (due to being unplugged for example).
