Application controlled encryption of web browser cached data
A browser cache-securing component facilitates online communication of confidential data, such as for financial information, purchasing transactions, or user identification. Caching webpages for subsequent presentation enhances user productivity and efficiency while reducing burdens on network resources. Yet, the security risks of intrusions into cache memory are mitigated by retaining encrypted data in cache memory without prior decryption. A modest overhead in decrypting when and if the webpage is to be presented again gains a security and privacy advantage without taking away functionality. Decrypted versions of confidential data can thereby be relegated to volatile memory. Upon termination of a session, a session key shared by a network server is deleted, preventing subsequent decryption. Executing the browser cache-securing component in a virtual machine environment allows multiple browser types to benefit from the security feature. |

Overlay modulation of COFDM using phase and amplitude offset carriers
Systems and methods are presented for transmitting additional data over preexisting differential COFDM signals by modulating existing data carriers with a phase and an amplitude offset. In exemplary embodiments of the present invention, additional data capacity can be achieved for an COFDM signal which is completely backwards compatible with existing satellite broadcast communications systems. In exemplary embodiments of the present invention additional information can be overlayed on an existing signal as a combination of amplitude and phase offset from the original QPSK symbols, applied for each information bit of the overlay data. With two additional levels of modulation, a receiver can demodulate the information from each of the previous stages and combine the information into a suitable format for soft decoding. The first stage of demodulation will be recovery of overlay data from the amplitude modulated D8PSK. Because other amplitude variations due to multi-path are also expected, the data gathered from the FFT in the receiver must be equalized to the channel conditions. After channel equalization has been performed, soft overlay data can then be derived from the distance off the unit circle. In order to recover the phase modulated overlay data, the equalized symbols must first be differentially demodulated and corrected for any common phase error offset. After common phase removal, overlay phase information can be obtained. |

Computer program, apparatus, and method for managing network
In response to a route-changing event, original routes on the network are changed to new routes. A destination-reachable range is identified as a range from which packets can reach an information processing device specified by a destination address. Modification of forwarding data is performed for a neighbor communication device which is located outside the destination-reachable range and adjacent to a communication device in the destination-reachable range, so as to enable forwarding of packets to that communication device in the destination-reachable range. The modified forwarding data is then transmitted to the neighbor communication device. The modification made to the forwarding data results in an additional destination-reachable range, which is thus added to the destination-reachable range. Another cycle of processing is then performed on the basis of the expanded destination-reachable range. |
