An Improved Method of Quantum Key Distribution Protocol
Classic encryption methods used in our life based on methematical ideas are unsafe actually, so quantum encryption is proposed nowadays. Althouth quantum eccryption is the unique method to protect datas and data transmission in theory, more processes are required during the production of quantum key to the achievement of encryption and decryption. Firstly, basic quantum key distribution protocol process is introduced in this paper. 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 Eves information, secrecy enhancement, etc. At last, based upon original improvements reserved selectively, the whole process of quantum key distribution protocol after improvement is introduced in detail.
