Abstract
A method and apparatus for use in authentication for secure wireless communication is provided. A received signal is physically authenticated and higher layer processed. Physical authentication includes performing hypothesis testing using a channel impulse response (CIR) measurement of the received signal and predetermined referenced data. Higher layer processing includes validating the signal using a one-way hash chain value in the signal. Once a signal is authenticated, secure wireless communication is performed.
