Abstract
Official abstract text for this publication.
A method and apparatus is used for generating a perfectly random secret key between two or more transceivers in a wireless communication network. In a point-to-point system, both transceivers produce an estimate of the channel impulse response (CIR) based on the received radio signal. The CIR estimation is synchronized and may include error correction and detection. A long secret key of bits is generated from a digitized version of the CIR estimate, from which a perfectly secret encryption key is derived by privacy amplification.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: receiving a radio signal at a first wireless transmit/receive unit (WTRU); receiving antenna configuration information from a second WTRU at the first WTRU; generating a channel impulse response (CIR) estimate at the first WTRU for the radio signal, wherein the CIR estimate is generated based, at least in part, on the antenna configuration information; determining a starting point within the CIR estimate at the first WTRU; transm…
