SecureChannelMessenger is a client-server application developed as part of the Computer and Network Security, CS432, course at Sabancı University, utilizing C# socket programming for secure and authenticated message broadcasting. This application serves as a robust platform for subscribers across different channels to send and receive messages in a secure, authenticated manner. The project encompasses two main modules, the Server module and the Client module, intricately designed to ensure secure communications within the network.
The Server module receives messages from clients and broadcasts them to the clients subscribed to a specific channel. The server manages client enrollments and initiates the secure environment.
The Client module registers to the Server, subscribes to a channel, and gets authenticated. Once authenticated, the client can securely send and receive messages through the subscribed channel.
