Method and apparatus for constructing a storage system from which digital objects can be securely deleted from durable media
In a data storage system, content-containing objects to be stored are added to a storage hierarchy that is based on content relationships. The content of each stored object is encrypted and a stub is associated with that object. For each stored object other than a root object, the stub comprises a function of a decryption key for the content of that object and the stubs of all of the ancestors of that object. The stubs can be used to calculate a new stub for a data object to be inserted into the storage hierarchy and to generate a decryption key for an existing object. Since these latter calculations for an object involve the stubs of all ancestors of that object, deleting a stub for an object securely deletes that object and all its descendants. An object can be moved by recalculating its stub. |

Web browser operating system
A Web browsing system using a browser operating system (BOS), which provides a trusted software layer on which Web browsers execute. The BOS runs the client-side component of each Web application (e.g., on-line banking, and Web mail) in its own virtual machine, which provides strong isolation between Web services and the user's local resources. Web publishers can thus limit the scope of their Web applications by specifying the URLs and other resources that their browsers are allowed to access, which limits the harm that can be caused by a compromised browser. Web applications are treated as first-class objects that users explicitly install and manage, giving them explicit knowledge about and control over downloaded content and code. An initial embodiment implemented using Linux and the Xen virtual machine monitor has been shown to prevent or contain about 87% of the vulnerabilities that have been identified in a conventional web browser environment. |

Method and apparatus for improving the resilience of content distribution networks to distributed denial of service attacks
Several deterrence mechanisms suitable for content distribution networks (CDN) are provided. These include a hash-based request routing scheme and a site allocation scheme. The hash-based request routing scheme provides a way to distinguish legitimate requests from bogus requests. Using this mechanism, an attacker is required to generate O(n2)amount of traffic to victimize a CDN-hosted site when the site content is served from n CDN caches. Without these modifications, the attacker must generate only O(n) traffic to bring down the site. The site allocation scheme provides sufficient isolation among CDN-hosted Web sites to prevent an attack on one Web site from making other sites unavailable. Using an allocation strategy based on binary codes, it can be guaranteed that a successful attack on any individual Web site that disables its assigned servers, does not also bring down other Web sites hosted by the CDN. |

Continuing execution in scout mode while a main thread resumes normal execution
A system that facilitates improving performance of a processor during scout mode. During a normal-execution mode, the system executes instructions for using main thread. Upon encountering a stall condition during execution of the main thread, the system generates a checkpoint. The system then enters a scout mode, wherein instructions are speculatively executed by a speculative thread to prefetch future memory references, but results are not committed to the architectural state of the processor. Upon encountering a memory reference during scout mode, the system issues a prefetch for the memory reference. If the stall condition that caused the processor to enter scout mode is resolved, the system uses the checkpoint to resume execution of the main thread from the instruction that caused the stall condition, and simultaneously continues executing instructions in scout mode using the speculative thread from the point where the speculative thread left off. |

Methods and apparatus for interfacing to a data storage system
A data storage system includes methods and apparatus that provide volumes for access by host computing devices. The volumes can have a storage size that is independently configurable from an actual amount of data storage that may or may not be associated with the volume. The volumes also have a persistent identifier. The volumes can have any amount of associated storage space allocated to the volume, including none, within the data storage system. Since the storage size and associated storage space are each independently configurable from each other, host that interface with the data storage system can perceive the volumes as being larger than they really are. A dynamic volume configuration technique is provided which allows storage space within storage devices in the data storage system to be dynamically associated and disassociated (i.e., added and removed) from the volumes on an as-needed basis, without requiring disruption of host activities with respect to the volumes. The persistent identifier of a volume allows all hosts and other data storage systems to “see” the volume. This allows a volume in one data storage system to have associated storage space from another volume in another data storage system. Using these techniques, the invention allows software applications and operating systems on hosts that interface to the data storage system to perceive that a volume is always present on the data storage system, even if storage space understood to be associated with the volume from the host's perspective is allocated elsewhere or is non-existent. |

Channel signal concealment in multi-channel audio systems
A parametric model is used for error concealment. The model filter allows for recovering signal components of original audio channel signals that now are lost or erroneous from signal components of at least one other audio channel. During error-free reception of valid frames, the parameters of that model will be derived and stored. In case of frame loss or frame error affecting the multi-channel information, a conjecture of the missing information is recovered by applying the model, using the stored parameters.

An optical processor for controlling a phased antenna array uses a frequency-shifted feedback cavity (FSFC), which includes a traveling-wave cavity. The FSFC incrementally delays and incrementally frequency shifts optical signals circulating in the traveling-wave cavity.

All previous information is erased. Then, moderate magnetic fields are applied to the same track and reverse a part of magnetic particles writing the second binary number. As the result, we obtain superimposed transitions between different magnetization states. The reading sensor detects the magnetization transitions and gives the result of logic operations. |

Image writing/display device and image writing/display method
An image writing/display device has a voltage applying section, a pressure applying section, an initialization controlling section, and an image writing controlling section. In a state in which a display medium having a pair of electrodes and a display layer that is sandwiched between the pair of electrodes and whose reflectance is changed is positioned, the voltage applying section applies voltage to the pair of electrodes for changing the reflectance of the display layer. The pressure applying section applies pressure for changing the reflectance of the display layer. The initialization controlling section makes the display layer a uniform reflectance by applying pressure to the display layer with the pressure applying section. The image writing controlling section writes an image by applying data voltage from the voltage applying section to specific regions, that correspond to image data, of the display layer between the pair of electrodes. |
