Abstract
The security of quantum cryptography based on time shifts has been mathematically proved. The procedures of preparing and measuring the most strongly localized states with a support in a finite frequency band are described. It has shown that measurements of states in the finite frequency band and a finite time window are sufficient for detecting any change in input states. The use of available multiplex fiber optic systems based on an arrayed waveguide grating for time-shift quantum cryptography is briefly discussed.
