  Abstract

In this study, the secure internet phone system using digital signature and data encryption with DES algorithm and EDE algorithm was implemented. And new key distribution algorithm was suggested utilizing the Diffie-Hellman algorithm. For reducing processing time, a table combined with S-BOX and P-BOX of the DES was used. The proposed system was implemented with Java and the results showed the processing time using DES algorithm for encryption was 1.46 seconds and that of EDE algorithm was 3.25 seconds respectively. This system can be applied to protect the copyright of sound products and data using internet.
