Abstract: Systems, methods, and instrumentalities are disclosed that allow a user to initiate migration of a credential from one domain to another domain. A request to initiate a migration of credentials from a first domain to a second domain may be initiated by a user (1a.). A remote owner may receive a message indicating that the migration has been requested. The message received by the remote owner may be an indication that the source and destination devices have performed internal checks and determined that a migration could proceed. The remote owner may evaluate source information received from the source device and destination information received from the destination device (6), (6a.), (6b.). Based on the evaluation of the source information and the destination information, the remote owner may determine that the migration is acceptable. The remote owner may send an indication to proceed with the migration (7), (7a.

Abstract: A receiver for generating a soft threshold value for use in measuring the power of a received signal includes a correlator, an automatic gain controller, a noise level measuring device, and a soft threshold device. The correlator is configured to receive the signal as an input and to produce a correlated signal. The automatic gain controller is configured to receive the signal as an input and to produce a gain control value. The noise level measuring device is configured to receive the signal as an input and to produce a noise level measurement. The soft threshold device is configured to receive the gain control value and the noise level measurement as inputs and to produce a soft threshold value. The soft threshold device is further configured to apply the soft threshold value to the correlated signal and to discard any correlated signals that are below the soft threshold value.

Abstract: A wireless transmit/receive unit (WTRU) includes a control plane (C-plane) packet data convergence protocol (C-PDCP) layer which performs ciphering of a signaling message. The C-PDCP layer is activated upon power up of the WTRU and initial security parameters are loaded to the C-PDCP layer. An initial connection signaling message and a user identity are ciphered using the initial security parameters even before the WTRU is authenticated. The initial security parameters including a ciphering key (CK) may be generated from system information broadcast from the network. The CK may be a public key for asymmetric encryption, and may be selected from a public key set broadcast by or derived from the network system information. An index of the selected public key may be separately encoded. Alternatively, the index may be communicated by using a Diffie-Hellman key exchange method.

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: The system and method of the present invention establishes a communication link between a user equipment (UE) and a base station in a communication system having a plurality of base stations which each transmit a common primary synchronization code (PSC) in a primary synchronization channel in conjunction with a base station specific secondary synchronization code (SSC) within a system frame, which receives with the UE an input signal including the PSC and SSC from at least one of the base stations. The UE analyzes the input signal to detect any received PSCs within a selected time period which has duration corresponding to the length of a system frame and determining a relative location of a strongest PSC within the selected time period. The input signal is then processed to remove the PSC from at least the determined PSC location. A secondary synchronization code (SSC) is then detected for the determined location from the processed signal. The communication link is then established using the detected SSCs.
