    摘要： A method and apparatus for securing location information and access control using the location information are disclosed. A wireless transmit/receive unit (WTRU) includes a location sensing entity and a subscriber identity module (SIM). The location sensing entity generates location information of the WTRU and the location information is embedded in a message in an SIM. A trusted processing module in the WTRU verifies integrity of the location information. The trusted processing module may be on the SIM. The location information may be physical location information or contextual location-related information. The trusted processing module is configured to cryptographically secure and bind the location information to the WTRU, and verify trust metrics of an external entity prior to granting an access to the location information or accepting information from the external entity. The trusted processing module may be a trusted computing group (TCG) trusted platform module (TPM) or mobile trusted module (MTM). The location information may be used for an authentication purpose or access control. The location information may be combined with time information.

    摘要： A method and system for generating a secret key from joint randomness shared by wireless transmit/receive units (WTKUs) 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.
