Online Chatting Protection system

Abstract

The great development of Internet applications with the increasing users within this open environment cause many problems related to data security and Internet web sites of intrusion certain users or attacking by others, so significant loss of data and information used for any purpose will occurs, there are more of security measures to be taken consideration account for the purpose of protection of sites and data, both from theft, alteration or destruction. This research builds a data protection system that is exchanged through text chat as a proposed protection system is used to improve the work of the DES algorithm by introducing a process as an intermediate stage rather than an S-Box similar to the encryption process by using the RSA method, this proposal system gives high Security and efficiency to protect data when it is transmitted over the normal networks or the Internet by combining these two methods where the data is sent encrypted to the other party, the proposed system has been implemented on the local network between the two devices running on Windows (10) and (Windows 7) As well as applied on the Internet in a continuous manner.
