摘要： Various embodiments are described that relate to random noise addition to a communication. A first secure network can employ a first encryption scheme and a second secure network can employ a second encryption scheme. In order to communicate between the first secure network and the second secure network such that the schemes are not decipherable, random noise can be added to a communication designated to transfer from the first secure network to the second secure network.

摘要： A personal mobile device receives a session-request message requesting establishment an encrypted-audio session with a call-initiating device. In response, one or more call-response inquiries are presented via a user interface of the mobile device. The one or more call-response inquiries include an accessory-status inquiry with respect to an accessory to the mobile device. The mobile device receives, via the user interface, an accessory-unready indication with respect to the accessory, which is associated with the presented accessory-status inquiry. In response to receiving the accessory-unready indication, the mobile device establishes a communication link with the call-initiating device and refrains from exchanging audio data with the call-initiating device via the established communication link. The mobile device makes an accessory-ready determination and responsively establishes the encrypted-audio session at least in part by receiving encrypted-audio data from the accessory and forwarding, via the established communication link, the encrypted-audio data to the call-initiating device.

摘要： Selective deciphering of a received signal, as taught herein, provides a number of advantages, including greater efficiency through the elimination or at least reduction of wasted decoding cycles. The technique, such as practiced in a user equipment or other wireless communication device, capitalizes on the advantageous recognition herein that the demodulation results obtained for at least some types of received data blocks may be inspected or otherwise evaluated for characteristic patterns that are indicative of whether the data block was or was not ciphered for transmission. That evaluation informs the selective deciphering decision.

摘要： The method includes a first encryption step of encrypting each of a plurality of data streams to obtain a respective encrypted data stream, a mapping step of mapping the plurality of encrypted data streams obtained in the first encryption step to a plurality of transmission streams for transmission via the optical transmission units, wherein the transmission streams and optical transmission units are in a one-to-one relationship, and wherein each transmission stream is mapped to by at least two of the plurality of encrypted data streams. The method further includes a second encryption step of encrypting each of the plurality of transmission streams to obtain a respective encrypted transmission stream, and a transmission step of transmitting each of the plurality of encrypted transmission streams obtained in the second encryption step via a respective optical transmission unit.

摘要： An electronic device may be configurable to operate in a scrambling mode and a non-scrambling mode while processing chat audio and microphone audio for a first player participating in an online multiplayer game via a game console. While operating in the non-scrambling mode, the electronic device may be configured to transmit the microphone audio to the game console without scrambling the microphone audio. While operating in the scrambling mode, the electronic device may be configured to scramble the microphone audio and transmit the scrambled microphone audio to the game console. The electronic device may be operable to select a scrambling key used to scramble the microphone audio based on a signal received by the electronic device that indicates a role of the player in the online multiplayer game. The role of the player may correspond to which of two or more opposing teams the first player is a member of in the online multiplayer game.

摘要： A first network device may discover one or more values of one or more parameters corresponding to a plurality of links and/or devices of the network. The first network device may compare the discovered one or more values of the one or more parameters to an expected one or more values of the one or more parameters. The first network device may determine whether to transmit data onto a network path between the first device and one of the plurality of devices based on a result of the comparison, wherein at least one of the plurality of links and/or devices are not part of the network path. The first network device may be operable to utilize the discovered parameter values to generate a security key which may be utilized to encrypt and/or scramble content prior to transmitting the content onto the network.

摘要： Embodiments of the invention provide reduced levels of interference to GPS receivers and/or to satellites. These embodiments allow frequencies that are proximate to GPS to be used by base stations and/or access points (such as femtocells) to provide forward and/or return link communications to user devices such as smartphones. Illustrative embodiments are provided wherein carriers of the 4G LTE standard (OFDM/OFDMA/SC-FDMA) are used by base stations and/or access points to provide wireless communications while reducing levels of interference to GPS and/or to satellites.
