![]() * Encrypt a message with peer's encryption key * (won't generate a new one if one exists already) The library pg1lib.h (provided) contains the following methods: The port number to listen on ( argument 1).You need to handle both.Īlso write a simple UDP server that takes in: Note that arg3 could be a string or a file name. The port number on the server ( argument 2).The host name of the server ( argument 1).More background information about public key encryption and socket programming is provided in the "Helpful Links" section at the end of this document. You also need to compute the round-trip-time (RTT) of your messages. The server will decrypt the message and reply with a checksum of the received message. The client will then send an encrypted message to the server. The program will build a UDP connection between the two hosts and exchange encryption keys. You will be writing a simple and secure communication protocol using UDP client and server. Write a simple UDP network client and server ![]() Goal: Refresh how to compile code, gain experience with network syscalls Fall 2019 CSE30264 Program 1 - Simple Secure UDP Programįall 2019 CSE30264 Programming Assignment 1 - Simple Secure UDP Program
