    • A method and apparatus for performing Joint Randomness Not Shared by Others (JRNSO) is disclosed. In one embodiment, JRNSO is determined in Frequency Division Duplex (FDD) using a baseband signal loop back and private pilots. In another embodiment, JRNSO is determined in Time Division Duplex (TDD) using a baseband signal loop back and combinations of private pilots, private gain functions and Kalman filtering directional processing. In one example, the FDD and TDD JRSNO embodiments are performed in Single-Input-Single-Output (SISO) and Single-Input-Multiple-Output (SIMO) communications. In other examples, the FDD and TDD embodiments are performed in Multiple-Input-Multiple-Output (MIMO) and Multiple-Input-Single-Output (MISO) communications. JRNSO is determined by reducing MIMO and MISO communications to SISO or SIMO communications. JRNSO is also determined using determinants of MIMO channel products. Channel restrictions are removed by exploiting symmetric properties of matrix products.

    • 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.

    • 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.
    • 一种用于多个无线发射/接收单元(WTRU)之间的安全直接链路通信的方法。 WTRU交换用于生成公共随机数的随机数。 从至少公共随机数生成组标识信息元素(GIIE),并将其转发给认证服务器。 认证服务器从GIIE生成组直接链路主密钥(GDLMK),作为密钥协商组的一部分匹配WTRU。 组密钥加密密钥(GKEK)和组密钥确认密钥(GKCK)也是基于通用随机数生成的,用于对GDLMK进行加密和签名,以使基站无法访问GDLMK。 还公开了一种用于选择密钥管理套件(KMS)以生成时间密钥的方法。 可以根据所选择的KMS设置KMS索引(KMSI),发送到另一个WTRU并用于建立直接链路。
