Security Analysis and Improvement for Kerberos Based on Dynamic Password and Diffie-Hellman Algorithm

This paper analyses the process of Kerberos authentication protocol, and finds the existing security problems of the protocol referring to some Kerberos improvement projects proposed in some papers at home and abroad, and puts forward the thoughts and methods using dynamic password to improve the encryption security during the process of interaction between the client and Kerberos key distribution center, and makes passwords securely exchanged by using Diffile-Hellman key algorithm.
