Conception of Client/Server System with Encrypted Data Exchanging Using Sockets

Abstract

Information security and computer networks allow keeping the confidentiality of data in order to facilitation of access to it with more privacy. Among the most models that rely on networks in sending data the client/server model, for ease for transmission and it is the model that is more compatible with most operating systems and methods of cryptography. From the theoretical side, we will present the most important titles that explain the concept of client/server and its components, and giving an overview of classical and modern encryption methods. In addition to designing a client/server model where we can encrypt files sent, and we will apply the advanced encryption standard, which is one of the latest encryption methods provided by the cryptography.
