Abstract Cryptography is a scientific method that used to transmit secret information. In contrast, quantum cryptography depends on physical laws encrypt information; when the computer appeared, classic encryption becomes inefficient. The commonly distribute keys, process called as key distribution (QKD). this paper, we consider efficiency of compared classical methods. Also, discuss security QKD against several attacks and provide analysis based probabilistic models. Additionally, paper explains how random numbers into sequence photons using system for key. This research demonstrates in sending distributing keys between communication parties. Thus, both sender receiver would be able obtain rather than
