Write a distributed networking application in Java consisting of a transmitter and a receiver that can ensure reliable data transfer. The application should use Java’s UDP sockets (classes DatagramPacket and DatagramSocket and their methods) and provide the necessary reliable data transfer functionality on the top of UDP’s unreliable communication services by implementing the data transfer protocol described below. The data transfer should be one-directional with data bytes flowing from the transmitter to the receiver. To prevent unauthorized access to the data, the payload sent to the receiver will be encrypted by the RC4 cipher. We will assume that the transmitter and the receiver have a shared secret (a 64-bit key), which will be used for encryption and decryption and will also automatically authenticate the communicating parties.
