Abstract:
1. A method for generating a secret key from joint randomness shared by a first wireless transmit/receive unit (WTRU) and a second WTRU, the method comprising: the second WTRU generating a second sampled channel impulse response (CIR) based on a channel between the first WTRU and the second WTRU; the second WTRU receiving a syndrome from the first WTRU, wherein the syndrome has been generated by the first WTRU from a first set of bits generated from a first sampled CIR based on the channel between the first WTRU and the second WTRU; the second WTRU generating the second set of bits from the syndrome received from the first WTRU and the second sampled CIR; and the second WTRU generating the secret key from the second set of bits.
