    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. The various embodiments of the present invention allow a user to hop securely and transparently from one site to another that belong to a pre-identified group of sites, after signing on just once to a secured proxy residing at the user's device.

    摘要： A method and an apparatus for performing physical layer security operation are disclosed. A physical layer performs measurements continuously, and reports the measurements to a medium access control (MAC) layer. The MAC layer processes the measurements, and sends a security alert to a security manager upon detection of an abnormal condition based on the measurements. The security manager implements a counter-measure upon receipt of the security alert. The measurements include channel impulse response (CIR), physical medium power measurement, automatic gain control (AGC) value and status, automatic frequency control (AFC) gain and status, analog-to-digital converter (ADC) gain, Doppler spread estimate, and/or short preamble matched filter output. The security manager may switch a channel, switch a channel hopping policy, change a back-off protocol, or change a beamforming vector upon reception of the security alert.

    摘要： A method and apparatus for generating physical layer security keys is provided. Channel impulse response (CIR) measurements are recorded. Each CIR measurement is associated with a time-stamp. Where possible, the time-stamps are paired with time-stamps that are associated with another plurality of CIR measurements. The CIR data associated with the paired time-stamps is aggregated. Each of the aggregated CIR measurements is aligned, and at least one CIR measurement is selected for use in secret key generation.

    摘要： A method for secure direct link communications between multiple wireless transmit/receive units (WTRUs). The WTRUs exchange nonces that are used for generating a common nonce. A group identification information element (GIIE) is generated from at least the common nonce and is forwarded to an authentication server. The authentication server generates a group direct link master key (GDLMK) from the GIIE to match WTRUs as part of a key agreement group. Group key encryption key (GKEK) and a group key confirmation key (GKCK) are also generated based on the common nonce and are used to encrypt and sign the GDLMK so that base stations do not have access to the GDLMK. Also disclosed is a method for selecting a key management suite (KMS) to generate temporal keys. A KMS index (KMSI) may be set according to a selected KMS, transmitted to another WTRU and used to establish a direct link.
