Abstract
We propose a new method for secure key distribution using white-light interferometry. In contrast to quantum key distribution, only classical waves are used and, therefore, single photons (and the practical problems associated with them) are avoided. The core idea is the employment of random but discrete delays on both sides of the communication channel. The security of the method currently cannot be proven and further investigations are necessary towards this goal.
