  • Patent number: 7281068
    Abstract: A disk management server (“DMS”), to manage a remote storage device; a wireless communication network; and a mobile computer create a system for secure remote booting of a mobile computer's operating system. To facilitate access to remote boot code, a multiple connection disk management server utilizes a trusted connection to negotiate communication security and an untrusted connection for transferring data once communication security has been established. The trusted connection is established through a physically securable interface, such as a wired network or line-of-site wireless network, e.g., infrared. Successful negotiation of communication security produces a security key that can be utilized to secure information exchange over the untrusted network. The untrusted connection may utilize any standard wireless communication protocol such as IEEE 802.11b.

  • Patent number: 7243219
    Abstract: Systems and methods of processing branch instructions provide for a bimodal predictor and a plurality of global predictors. The bimodal predictor is coupled to a prediction selector, where the bimodal predictor generates a bimodal prediction for branch instructions. The plurality of global predictors is coupled to the prediction selector, where each global predictor generates a corresponding global prediction for a branch instruction using different history or stew lengths. The prediction selector selects branch predictions from the bimodal prediction and the global predictions in order to arbitrate between predictors. The arbitration, update, and allocation schemes are designed to choose the most accurate predictor for each branch. Lower level predictors are used as filters to increase effective predictor capacity. Allocate and update schemes minimize aliasing between predictors.

  • Patent number: 6961849
    Abstract: A method, system, and computer program product for selectively encrypting one or more elements of a document using style sheet processing. Disclosed is a policy-driven augmented style sheet processor (e.g. an Extensible Stylesheet Language, or “XSL”, processor) that creates a selectively-encrypted document (e.g. an Extensible Markup Language, or “XML”, document) carrying key-distribution material, such that by using an augmented document processor (e.g., an augmented XML processing engine), an agent can recover only the information elements for which it is authorized. The Document Type Definition (DTD) or schema associated with a document is modified, such that the DTD or schema specifies a reference to stored security policy to be applied to document elements. Each document element may specify a different security policy, such that the different elements of a single document can be encrypted differently (and, some elements may remain unencrypted).
