摘要:
A method is disclosed and apparatus is described whereby plain text is modified before it is input to a binary key generator (encryptor). According to the invention, a plain text bit may be modified by a current modifying bit, which in turn, is based on a prior modifying bit, a prior plain text bit, and a prior ciphered text bit. The only data path provided to the transmitter is the encrypted key generator cipher text output. As a result, the only feed-foward path of the plain text to the channel is through the key generator, and thus the fault-immune physical barrier between the plain text and the cipher information inherent with the key generator is maintained. The invention provides a way of utilizing conventional binary key generators to digitally encrypt for radio transmission multilevel sub-band coded speech.

According to the invention, an information signal, such as a information signal, is sampled, quantized and processed digitally through an information encoder. Digitally processed samples produced by the encoder are modulated onto a communication channel to create channel symbols having a magnitude of modulation proportional to a characteristic of a respective digitally processed sample. Both a radio frequency (RF) transmission embodiment, and a wireline embodiment are provided. In a final aspect of the present invention, encryption is provided to ensure communication privacy.

A method includes generating a content editing command file devoid of content by editing content. The content editing command file may be used to edit other copies of the same content that was edited to generate the content editing command file. Multiple content editing command files having some variability may be combined to form an aggregated content editing command file.

A method and apparatus determines whether a wireless apparatus (106a) that is operative to communicate over both a wireless wide area network (104) and a wireless local area network (102), will allow shared use of its short range wireless resources, such as LAN radio frequency bandwidth, optical bandwidth or other local area wireless resources, with other proximal wireless units (106b-106n) in the wireless local area network (102). In addition, the method and apparatus generated reward data (116) to provide a reward, such as free telephone calls, account credits, price reductions, or other rewards, so that a billing system is updated when a wireless apparatus (106a-106n) has been designated as allowing shared use of its wireless resources by other proximal wireless units.
摘要:
A wireless mobile device (104) provides challenge/response based authentication by receiving a first portion of a challenge (132) from an external authentication unit (102), such as a network unit, and utilizes an internal partial challenge generator (114) that internally provides a second portion of the challenge (138) and provides the internally generated second portion of the challenge (138) back to the authentication unit (102). The wireless mobile device (104) also includes combiner logic (116) that combines the externally received first portion of the challenge (132) with the internally produced second portion of the challenge (138) to produce a complete challenge (144). The wireless mobile device (104) then utilizes a response generators (118) that takes the complete challenge (144) that was produced and generates a response (146) based on the complete challenge (144), and other secret information (110) if desired using a suitable cryptographic operation. The response (146) is sent back to the authentication unit (102) for verification.

Disclosed are electronic devices and methods of electronic devices having a housing including a wireless actuator without an electrical interface, the wireless actuator located on the housing, the wireless actuator being configured to provide tactile feedback and configured to generate an acoustic signal with a unique acoustic signature upon actuation. Included is at least one accelerometer being configured to receive a mechanical or acoustic stimulus and/or an acoustic signal which can include an impulse response being a brief non-periodic and/or non-repeating signal such as a tap or a repeating signal such as a tone, to generate an identifying signal. Also included is a processor configured to receive an identifying signal to generate a control signal based on the received acoustic signal correlated to the acoustic signature. The control signal can provide initiation of any function or application of the device.

A method and system for managing communication sessions in a plurality of wireless communication networks is provided. The plurality of wireless communication networks includes one or more home communication networks and one or more guest communication networks. The method at a communication device includes predicting (502) a coverage gap in a home communication network. The coverage gap is within a coverage region of the home communication network. Further, the method includes temporarily utilizing (504) at least one communication resource of a guest communication network when the communication device enters the coverage gap and when the at least one communication resource of the guest communication network is substantially available. The at least one communication resource enables communication at the communication device. The utilization of the at least one communication resource of the guest communication network is controlled by at least one of the home communication network and an overlay network.

A method (300) of and secure server (200) for providing secure assistance with control of a communications unit (101, 103, 105) is disclosed. The method includes receiving (303) an instruction message via a network that corresponds to voiced instructions from the communications unit; parsing (307) the voiced instructions and sending (409) the results to assistant agents having limited access to sensitive information or only partial access to the instructions maintains security of sensitive information. The assistant agents convert (411) the portions of voiced instructions to commands; and the commands are assimilated (415) in a secure server along with other information to provide a control message corresponding to the commands. The control message is sent to the communications unit, thereby securely assisting with the control of the communications unit.
