Abstract

This paper addresses the study of the Quantum Key Distribution (QKD) BB84 protocol used at the telecoms wavelength 1550 nm with Single Mode Fiber (SMF) and realistic physical parameters features. We simulate the protocol with considering an optimized attack strategy and show that the Heralded Single Photon Source (HSPS) is more advantageous than the Attenuated Laser (AL) for mainly security considerations.
