摘要： A smart antenna steering algorithm operates in response to different functions monitored by the media access control (MAC) layer within a client station. One function is when the MAC layer indicates that the client station has been placed in a power savings mode. In response, the antenna algorithm stores an index of the currently selected antenna. Another function is when the MAC layer indicates that the client station has not been synchronized, associated and authenticated with an access point. In response, the algorithm selects an omni-directional antenna beam as the default antenna beam. Another function is when the MAC layer provides beacon period synchronization information to the antenna steering algorithm so that the algorithm can update its own timer.

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： The present invention is related to a wireless communication system. 3G UMTS mobile phone systems rely on a protected smart card called the UMTS integrated circuit card (UICC) that provides UMTS subscriber identity module (USIM) applications as a basis or root of various security measures protecting the communication path between the 3G mobile terminal and the UMTS wireless network (or UTRAN). Disclosed is a method by which the UICC exchanges information with a terminal, such as an Internal Key Center (IKC 1250) and a Bootstrapping Server Function (BSF 1270) enables a procedure where multiple local keys specific to applications and Network Application Functions (NAFs) (Ks_local) are used for authentication and to encrypt and decrypt messages.

摘要： An apparatus and methods that use trusted platform modules (TPM) to perform integrity measurements of multiple subsystems are disclosed. The state of platform configuration registers (PCRs) after boot up are stored as the base state of the system. In another embodiment, and application that is to be verified requests that its state be extended from the base state of the system. When such a request is received, the state of the system is extended directly from the base state PCR contents and not from the system state. In another embodiment, a virtual PCR is used, where such a virtual PCR uses a larger memory space than a conventional TPM provides for a physical PCR, by use of encrypted storage on external, protected memory.

摘要： A method for implementing a smart antenna in establishing association between a station (STA) and an access point (AP) in a wireless local area network begins by transmitting a beacon frame by the AP on one antenna beam. The beacon frame is received at the STA, which measures the signal quality of the beacon frame. The AP switches to a different antenna beam and repeats the method until the beacon frame has been transmitted on all antenna beams. The STA associates to the AP that transmits the beacon frame with the highest signal quality on one of its antenna beams. A similar method may be used in which the STA sends a probe request frame to the AP, which then responds with probe response frames sent on multiple antenna beams.
