Abstract: A secret stream of bits begins by receiving a public random stream contained in a wireless communication signal at a transmit/receive unit. The public random stream is sampled and specific bits are extracted according to a shared common secret. These extracted bits are used to create a longer secret stream. The shared common secret may be generated using JRNSO techniques, or provided to the transmit/receive units prior to the communication session. Alternatively, one of the transmit/receive unit is assumed to be more powerful than any potential eavesdropper. In this situation, the powerful transmit/receive unit may broadcast and store a public random stream. The weaker transmit/receive unit selects select random bits of the broadcast for creating a key. The weaker transmit/receive unit sends the powerful transmit/receive unit the selected bit numbers, and powerful transmit/receive unit uses the random numbers to produce the key created by the weaker transmit/receive unit.

The stored data is classified in the memory of the WTRU. The WTRU detects an event and transmits a notification signal to the trusted entity in response to the event detected. The trusted entity transmits a readiness signal to the WTRU. The WTRU transmits data classified for transfer to the trusted entity, and the trusted entity stores the data classified for transfer in a memory of the trusted entity.

Abstract: A method and apparatus for securing wireless communications are disclosed. A watermark message is encoded to watermark message symbols. A cover message is encoded to cover message symbols. The watermark message symbols are then overlaid onto the cover message symbols to generate a watermark-embedded cover message in a physical layer. The watermark message symbols have a substantially lower amplitude than the cover message symbols. Thus, the watermark message introduces small perturbation around the constellation points of the cover message symbols. The watermark message symbol may span or spread over a plurality of cover message symbols and may be encrypted with a secret key. The watermark message is used for improving receiver performance by transmitting additional information or for security enhancement purposes. The watermarking function may be selectively turned on and off.

Abstract: The present invention relates to secret key generation and authentication methods that are based on joint randomness not shared by others (JRNSO), in which unique channel response between two communication terminals generates a secret key. Multiple network access points use a unique physical location of a receiving station to increase user data security. High data rate communication data is encrypted by generating a random key and a pseudo-random bit stream. A configurable interleaving is achieved by introduction of JRNSO bits to an encoder used for error-correction codes. Databases of user data are also protected by JRNSO-based key mechanisms. Additional random qualities are induced on the joint channel using MIMO eigen-beamforming, antenna array deflection, polarization selection, pattern deformation, and path selection by beamforming or time correlation. Gesturing induces randomness according to uniquely random patterns of a human user's arm movements inflected to the user device.

Abstract: In a wireless communication system comprising at least one wireless transmit/receive unit (WTRU), a base station, and a radio network controller (RNC), a method for constant envelope orthogonal frequency division multiplexing (CE-OFDM) modulation comprises the WTRU performing an inverse transform on the data. The WTRU next performs constant envelope (CE) modulation on the data and transmits the CE-OFDM data to the base station. The base station receives the data and CE demodulates the data. The base station performs a transform on the demodulated data.

Abstract: A wireless mesh network with digital rights management (DRM) interoperability is disclosed. A first DRM-capable mesh point (MP) performs a discovery procedure for detecting neighbor MPs and identifies at least one other DRM-capable MP among the detected neighbor MPs. The first DRM-capable MP then performs an association procedure only with the DRM-capable MPs. The first DRM-capable MP assigns DRM roles to the associated DRM-capable MPs. A digital content is then distributed from the first DRM-capable MP to another DRM-capable MP via the mesh network. The DRM interoperability may be based on a networked environment for media orchestration (NEMO) architecture proposed by the Coral Consortium or any DRM interoperability architectures.

Abstract: A sensing apparatus having a sensing functionality controller and a method of detecting the sensing apparatus is disclosed. A signal generation unit embedded in the sensing apparatus operates in conjunction with the sensing functionality controller to support the sensing functionality of the sensing unit. The signal generation unit generates one or more sensing functionality support signals used to enhance content obtained by the sensing unit, (e.g., a flash for illuminating a sensed target such that content obtained by the sensing unit is not too dark, or a sound or light-based auto focus signal to make sure that the content is not out of focus). When the sensing functionality controller is activated, the same signal generation unit generates a detectable warning signal, (e.g., sound, light, radio wave), which indicates that the sensing functionality controller has been activated and/or the sensing unit is sensing.

The WTRU includes a content generation unit, a watermark incorporation unit, and a communication subsystem. The content generation unit is embedded in the WTRU and generates content, such as audio, video, image, text or a combination thereof. The watermark incorporation unit determines the type of watermarks that should be incorporated in the content and incorporates the watermarks in the content. The communication subsystem transmits the watermarked content.

Abstract: In a communications device operating with a blind signal separation (BSS) processor, an initial mixing matrix is formed based upon the different summations of the source signals received by the antenna array. The initial mixing matrix is evaluated to determine a minimum rank that is necessary for at least one source signal to be useable after having been separated from the initial mixing matrix and decoded. An additional mixing matrix is then formed, and also includes the different summations of the source signals. If the rank of the additional mixing matrix is less than the minimum rank associated with the initial mixing matrix, then the source signals are modified so that the rank of the additional mixing matrix is increased.

The identification key is embedded into the content object by the wireless device.

Abstract: A method and apparatus are disclosed for selectively regulating devices. In a wireless communication system, a regulation zone is defined. Devices within a regulation zone (e.g. an electronic do-not-disturb (EDND) zone) are regulated by generating and transmitting inhibiting signals into or near the regulation zone. The inhibiting signals may be messages instructing devices to disable one or more of their sensing components or actual interference signals that prevent sensing components from functioning properly or watermarks that mark illicit recordings so that such illicit recordings are precluded from being transmitted over the network.

The cover signal is the primary communication signal, and may be binary bits, multi valued symbols, analog waveforms, or any other type of primary communication signal. Security strength indication, location tracking, intrusion detection and transmission of non-security information using watermarks are disclosed, along with a system for managing watermarks.

Abstract: Signals encoded with watermark information are generated and broadcast into a protected area for capture by illicit recording devices along with their intended targets. An illicit recording in which at least a portion of the broadcast watermark signals are recorded is obtained and correlated with a known position of the broadcast watermark signals to yield the location of illicit recording devices.

Illicit recordings containing the broadcast watermark are obtained and correlated with corresponding recordings taken by the surveillance device to identify the location of illicit recording devices. In an alternate embodiment, the surveillance device further monitors the quality of the broadcast watermark signals and adjusts them accordingly to achieve a desired quality level.
