In this letter, we consider the information theoretically secure key agreement where the
legitimate users have a virtual eavesdropper to estimate the statistics of wiretapping. We
propose a computational procedure which can estimate the virtual eavesdropper's
conditional entropy even with the finite number of pilot pulses and without restricting any
probatility family for the wiretap channel.

Abstract
In this letter, we consider the information theoretically secure key agreement where the legitimate users have a virtual eavesdropper to estimate the statistics of wiretapping. We propose a computational procedure which can estimate the virtual eavesdropper’s conditional entropy even with the finite number of pilot pulses and without restricting any probatility family for the wiretap channel.
