METHOD AND SYSTEM FOR SECURING WIRELESS COMMUNICATIONS
First Claim
1. In a wireless communication system including a wireless transmit/receive unit (WTRU) and a serving network (SN), a method for providing secure wireless communications, the method comprising:
- (a) the WTRU and a Node B performing joint randomness not shared by others (JRNSO) measurements to generate JRNSO bits based on a channel impulse response (CIR) estimate between the WTRU and the Node B;
(b) the WTRU and the Node B performing a reconciliation procedure to generate common JRNSO bits;
(c) the Node B sending the common JRNSO bits to the SN; and
(d) the WTRU and the SN securing a session key used for security using the common JRNSO bits.

Abstract
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.
