Secure Web Transfer Base on Diffie-Hellman Key Exchange Algorithm
Xiaodong Li · Journal of Changchun Post and Telecommunication Institute · 2005
The communicating information on Web must be encrypted by use of SSL(Secure Sockets Layer) protocol which is the common method of the secure transmission. This method is slow and deteriorates the performance of the Web server. A new method for securing transmission by use of DH(Diffie-Hellman) key exchange algorithm and DES(Data Encryption Standard) algorithm to transfer the DH parameters directly is presented. Web server and client compute the shared key and encrypt the essential communicating information, the secure transmission is insured and the influence of the new method compared with SSL on Web server performance come down 70%. The better effect is obtained by this method in Finance Security Management Information System.
