摘要： A wireless transmit/receive unit (WTRU) includes a control plane (C-plane) packet data convergence protocol (C-PDCP) layer which performs ciphering of a signaling message. The C-PDCP layer is activated upon power up of the WTRU and initial security parameters are loaded to the C-PDCP layer. An initial connection signaling message and a user identity are ciphered using the initial security parameters even before the WTRU is authenticated. The initial security parameters including a ciphering key (CK) may be generated from system information broadcast from the network. The CK may be a public key for asymmetric encryption, and may be selected from a public key set broadcast by or derived from the network system information. An index of the selected public key may be separately encoded. Alternatively, the index may be communicated by using a Diffie-Hellman key exchange method.

摘要： A wireless transmit/receive unit (WTRU) and a Node B, respectively, perform joint randomness not shared by others (JRNSO) measurement to generate JRNSO bits based on a channel estimate between the WTRU and the Node B. The WTRU and the Node B then perform a reconciliation procedure to generate a common JRNSO bits. The Node B sends the common JRNSO bits to a serving network. The WTRU and the SN secure a session key (such as an integrity key, a cipher key and an anonymity key), using the common JRNSO bits. The JRNSO measurements are performed on an on-going basis, and the session key is updated using a new set of common JRNSO bits. The JRNSO bits may be expanded by using a pseudorandom number generator (PNG) or a windowing technique. A handover may be intentionally induced to increase the JRNSO bits generation rate.
