  • Publication number: 20030051135
    Abstract: A computer system comprises at least one computer and at least one storage device coupled together via a network. The computers can store data on and read data from network storage devices. Preferably, the computers encrypt data as part of the transmission protocol. The encrypted data is then sent to the storage device where the packets are parsed and the encrypted data is stored in its encrypted form. When a computer requests data that is stored on the storage device, the storage device retrieves the requested data (which is encrypted) and transmits the encrypted data to the computer that requested the data. The computer then decrypts the encrypted data to recover the original data. Alternatively, the storage device again encrypts the already encrypted data when sending the data back to the requesting computer. The twice encrypted data is then received by the computer and twice decrypted to recover the original data.

  • Patent number: 6502203
    Abstract: A method and system of quorum negotiation utilizing power mains. Unlike current systems, this communication is provided as a secondary channel, with the primary channel being a standard network system. By using this technique, if the heartbeat is lost over the primary communication system, the secondary, power-mains system can be used to check the heartbeat to validate whether or not the “lost” system is still in operation. If communication cannot be established over the power mains, it is assumed that the “lost” system is down and should be dropped from any cluster.

  • Publication number: 20020174381
    Abstract: A computer system includes multiple controllers that assist in executing the Power-On Self Test (POST) sequence to minimize the time required to complete system initialization. By shifting some of the responsibilities for executing the POST sequence to other controllers within the system, the testing and initialization of system devices can proceed concurrently. The controllers interface with peripheral devices, and include a register set that includes command information for initializing the testing and initialization of associated peripherals. The register set also includes dedicated bits for indicating the status of testing and initialization cycles, which can be read by the CPU to determine if testing or initialization is in progress, if it has completed, and if any errors have occurred. The register set also includes a configuration register for indicating configuration information and operating parameters of the initialized drive or peripheral.

  • Patent number: 6477799
    Abstract: A self-orienting logo assembly so that the logo is always in a horizontal orientation. In the preferred embodiments the logo is located on a disk. The disk is weighted or otherwise designed to have its weight distributed nonuniformly. The disk is located inside a housing. The housing is attached to the computer or other equipment bearing the logo. When the housing is located in a vertical plane the disk rotates to allow the logo to remain horizontal. The disk can be rotationally mounted to the housing or can be suspended in liquid. In an alternate embodiment the disk can have a magnet incorporated so that when the disk is in a horizontal orientation it can act as a compass. In another embodiment a portion of the disk is removed and the housing contains an additional logo or wording. The rotation of the disk can then cover or expose the additional logo or wording.

  • Patent number: 6463495
    Abstract: A method and system of intrachassis computer component command and control. The existing power rail is used as network connectivity. Further, the CEBus standard (or a CEBus standard modified for the particular power bus) is used to provide platform management functionality. This management functionality is similar to that provided by the proposed IPMI specification. However, the management functionality is implemented intrachassis, that is, it is applied to the internal components of the machine. Particularly advantageous functions, such as rollcall enumeration and command authentication and verification, are included in a preferred embodiment. Further, because these innovative techniques utilize the existing power rail, no additional external cables are required.

  • Patent number: 6400823
    Abstract: A method for generating system passwords derived from an external encryption algorithm and plain text user passwords entered during a secure power-on procedure. At some point during the secure power-up procedure, the computer system checks for the presence of an external token or smart card that is coupled to the computer through specialized hardware. The token or smart card is used to store an encryption algorithm furnished with an encryption key that is unique or of limited production. Following detection of the external token, the computer user is required to enter a user password. The user password is encrypted using the encryption algorithm contained in the external token, thereby creating a system password. The system password is then compared to a value stored in secure memory. If the two values match, the power-on sequence is completed and the user is allowed access to the computer system or individually secured resources.

  • Patent number: 6370649
    Abstract: A computer system according to the present invention implements a self-modifying “fail-safe” password system that allows a manufacturer or site administrator to securely supply a single-use password to users who lose a power-up password. The fail-safe password system utilizes at least one fail-safe counter, an encryption/decryption algorithm, a public key, and a secure non-volatile memory space. The fail-safe password is derived by generating a hash code using SHA, MD5,or a similar algorithm and encrypting the result. The fail-safe password is then communicated to the user. After the user enters the fail-safe password, the computer system generates an internal hash value and compares it with the hash code of the decrypted fail-safe password. When the decrypted fail-safe password matches the internal hash value, the user is allowed access to the computer system.

  • Patent number: 6363449
    Abstract: A method and system of interchassis and intrachassis computer component command and control. The existing power rail is used for network connectivity for intrachassis command and control. An existing common power mains can be used for interchassis command and control. Further, a protocol, for example, the Consumer Electronic Bus (CEBus) protocol (or a CEBus protocol modified for the particular power rail) can be used to provide interchassis and intrachassis platform management functionality. This management functionality is similar to that provided by the proposed Intelligent Platform Management Interface (IPMI) specification. A chassis bridge controller is used to interface the intrachassis power rail command and control infrastructure to an exterior network. External systems (interchassis communications) can communicate to the bridge via the particular protocol over an existing common power mains as a secondary channel exterior network.

  • Patent number: 6288843
    Abstract: An apparatus, method and system are provided for scanning documents, and creating holographic and panoramic images. The apparatus provides two sets of prisms, one set of which is made of electro-optical material. The prisms are arranged in alternating rows to form a sheet. The prism sheet can be laid fiat or rolled into a cylinder. A sequencer is used to activate individual electro-optical prisms so that the image is reflected into the sheet. A second prism is used to reflect the image into an image receptor such as a camera. By sequentially activating the electro-optical prisms, successive image portions of an object or objects can be presented to the image receptor. If the image receptor accepts digital input, the sequential images can be post-processed in a microprocessor to create a holographic or panoramic image. Similarly, images of documents can also be scanned and the images received can be digitized for processing, storage and/or transmission.

  • Patent number: 6119228
    Abstract: A method for providing secure remote control commands in a distributing computer environment. In the preferred embodiment of the invention, a network administrator or network management software creates a shutdown record, including an index or time stamp, for powering down a specified network computer(s). Prior to broadcast over the network, a secure one-way hash function is performed on the shutdown record. The result of the one-way hash function is encrypted using the network administrator's private key, thereby generating a digital signature that can be verified by specially configured network nodes. The digital signature is appended to the original shutdown record prior to broadcast to the network. Upon receiving the broadcast message, the targeted network computer(s) validates the broadcast message by verifying the digital signature of the packet or frame. The validation process is performed by decrypting the hash value representation of the shutdown record using the network administrator's public key.
