Abstract
A new method of quantum cryptography using the frequency or direction modulation of weak light pulses and a new protocol for revealing ''eav esdropping'' are described. The method is grounded on the impossibilit y to reproduce with certainty the initial frequency f(omega) or space f(k) spectrum of a detected photon.
