Abstract :
We propose a security proof for a new class of quantum key distribution protocol namely Improved-SARG04. This protocol differs from BB84 and SARG04 protocol in the sifting process and provably outperforms those protocols against Photon Number Splitting attack at zero error, with secure transmission distance of 125 km of SSMF.
