Development Of A Client / Server Cryptography-Based Secure Messaging System Using RSA Algorithm

Ferdi SÖNMEZ,; Mohammed Khudhair Abbas

The effectiveness of the information system in many ways depends on its architecture and how does data are transmited among different parties. One of the most popular architecture is a client/server architecture. Practically, one of such advantages were the centralization of data storage and processing and the flexibility for applying authentication methods and encryption algorithms. While the number of clients increase its require increasing the authentication and encryption level as high as possible. Client/server is a technology that allows to open an interactive session between the user's browser and the server. In this study, we used client/server architecture to accomplish secure chat between clients without the server being able to decrypt the message by using one layer of encryption between the clients and the server, and then a second layer of encryption between the clients in a chat room. All the used encryption processes based on RSA (Rivest- Shamir-Adelman) algorithm.
