System for rebuilding dispersed data
ActiveUS20070079082A1Reliably and securely protectImprove privacyError detection/correctionDigital data protectionGrid resourcesInformation dispersal
A digital data file storage system is disclosed in which original data files to be stored are dispersed using some form of information dispersal algorithm into a number of file “slices” or subsets in such a manner that the data in each file share is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other file shares. These file shares are stored on separate digital data storage devices as a way of increasing privacy and security. As dispersed file shares are being transferred to or stored on a grid of distributed storage locations, various grid resources may become non-operational or may operate below at a less than optimal level. When dispersed file shares are being written to a dispersed storage grid which not available, the grid clients designates the dispersed data shares that could not be written at that time on a Rebuild List. In addition when grid resources already storing dispersed data become non-available, a process within the dispersed storage grid designates the dispersed data shares that need to be recreated on the Rebuild List. At other points in time a separate process reads the set of Rebuild Lists used to create the corresponding dispersed data and stores that data on available grid resources.

Authentication and authorization methods for cloud computing security
ActiveUS8769622B2Retain controlKey distribution for secure communicationDigital data processing detailsResource poolThird party
An authentication and authorization plug-in model for a cloud computing environment enables cloud customers to retain control over their enterprise information when their applications are deployed in the cloud. The cloud service provider provides a pluggable interface for customer security modules. When a customer deploys an application, the cloud environment administrator allocates a resource group (e.g., processors, storage, and memory) for the customer's application and data. The customer registers its own authentication and authorization security module with the cloud security service, and that security module is then used to control what persons or entities can access information associated with the deployed application. The cloud environment administrator, however, typically is not registered (as a permitted user) within the customer's security module; thus, the cloud environment administrator is not able to access (or release to others, or to the cloud's general resource pool) the resources assigned to the cloud customer (even though the administrator itself assigned those resources) or the associated business information. To further balance the rights of the various parties, a third party notary service protects the privacy and the access right of the customer when its application and information are deployed in the cloud.

Storage mapping and partitioning among multiple host processors in the presence of login state changes and host controller replacement
InactiveUS6260120B1Input/output to record carriersData processing applicationsData portControl store
A storage controller for controling access to data storage has a memory and at least one data port for a data network including host processors. The memory is programmed to define a respective specification for each host processor of a respective subset of the data storage to which access by the host processor is restricted, and each specification is associated with a host identifier stored in the memory. When the storage controller receives a data access request from a host processor, it decodes a host identifier from the data access request, and searches the memory for a host identifier matching the host identifier decoded from the request. Upon finding a match, the respective specification of the respective subset for the host processor is accessed to determine whether or not storage specified by the storage access request is contained in the respective subset. If so, then storage access can continue, and otherwise, storage access is denied. Preferably the host identifier decoded from the request is a temporary address assigned by the network, and also stored in the memory in association with each respective specification is a relatively permanent identifier for the host processor.

Secure network switching infrastructure
InactiveUS20080189769A1Reduces the trusted computing baseReduce overheadDigital data processing detailsUser identity/authority verificationNetwork packetNetwork control
Use of a centralized control architecture in a network. Policy declaration, routing computation, and permission checks are managed by a logically centralized controller. By default, hosts on the network can only route to the network controller. Hosts and users must first authenticate themselves with the controller before they can request access to the network resources. The controller uses the first packet of each flow for connection setup. When a packet arrives at the controller, the controller decides whether the flow represented by that packet should be allowed. The switches use a simple flow table to forward packets under the direction of the controller. When a packet arrives that is not in the flow table, it is forwarded to the controller, along with information about which port the packet arrived on. When a packet arrives that is in the flow table, it is forwarded according to the controller's directive.

In some embodiments, the invention is a personal digital network (“PDN”) including hardware (sometimes referred to as Ingress circuitry) configured to transcrypt encrypted content that enters the PDN. Typically, the transcryption (decryption followed by re-encryption) is performed in hardware within the Ingress circuitry and the re-encryption occurs before the decrypted content is accessible by hardware or software external to the Ingress circuitry. Typically, transcrypted content that leaves the Ingress circuitry remains in re-encrypted form within the PDN whenever it is transferred between integrated circuits or is otherwise easily accessible by software, until it is decrypted within hardware (sometimes referred to as Egress circuitry) for display or playback or output from the PDN. Typically, the PDN is implemented so that no secret in Ingress or Egress circuitry (for use or transfer by the Ingress or Egress circuitry) is accessible in unencrypted form to software or firmware within the PDN or to any entity external to the PDN. Other aspects of the invention are methods for protecting content in a PDN (e.g., an open computing system) and devices (e.g., multimedia graphics cards, set top boxes, or video processors) for use in a PDN.
