摘要： 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.

摘要： A method and apparatus for password management and single sign-on (SSO) access based on trusted computing (TC) technology. The methods implement the Trusted Computing Group (TCG)'s trusted platform module (TPM), which interacts with both proxy SSO unit and web-accessing applications to provide a secure, trusted mechanism to generate, store, and retrieve passwords and SSO credentials.

摘要： An authentication method selection using a home enhanced Node B (H(e)NB) profile is disclosed. A method for selecting an H(e)NB authentication method includes authenticating at least one of the device or the hosting party module by a security gateway (SeGW). The SeGW receives a request from the H(e)NB to start the authentication process. Based on information received from the H(e)NB and an authentication information server, the SeGW determines how to authenticate the H(e)NB. The possible authentication methods include device authentication only, device authentication and hosting party module authentication, requesting the H(e)NB to perform authentication using Extensible Authentication Protocol-Authentication and Key Agreement, or authentication of both the H(e)NB and one or more WTRUs connected to or attempting to connect to the H(e)NB.

摘要： 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.

摘要： The present invention is related to a generalized rake receiver for a wireless communication system. The rake receiver comprises a plurality of finger correlators and a plurality of escort correlators. Each finger correlator demodulates each multipath components of the transmitted signal. The escort correlator is used for multipath tracking for optimal finger placement and weight estimation for demodulation. The escort correlator is located in vicinity of multipath center and is programmable within a chip and at a resolution finer than a chip. Weight vector is estimated using the estimate of the total base station energy based upon the pilot information from the base stations in soft-handoff.

摘要： A method and system for generating a secret key from joint randomness shared by wireless transmit/receive units (WTRUs) are disclosed. A first WTRU and a second WTRU perform channel estimation to generate a sampled channel impulse response (CIR) on a channel between the first WTRU and the second WTRU. The first WTRU generates a set of bits from the sampled CIR and generates a secret key and a syndrome, (or parity bits), from the set of bits. The first WTRU sends the syndrome, (or parity bits), to the second WTRU. The second WTRU reconstructs the set of bits from the syndrome, (or parity bits), and its own sampled CIR, and generates the secret key from the reconstructed set of bits.
