All Classical cryptographic methods used in our life based on mathematical ideas & computational assumption are actually unsafe, so quantum cryptography is proposed nowadays Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. QKD will be an important part of future cryptographic infrastructures. It can provide long-term confidentiality for encrypted information without reliance on computational assumptions. Although QKD still requires authentication to prevent man-in-the-middle attacks. Firstly, In this paper At quantum key distribution protocol process is introduced. Secondly, several improvements to the basic steps of two references are reviewed because of its defects, mainly about identity authentication in order to prevent communication partners' counterfeit, including errors removing, estimating Attacker's information, secrecy enhancement, etc. At last, based upon original improvements reserved selectively, the whole process of quantum key distribution protocol after improvement & then comparison is introduced in detail.
