project Description :
There are a number of objectives to this assignment beyond just a simple socket programming assignment. First, if you have not ever programmed sockets before, it is relatively straightforward, but still an effort is needed. Second, it will help you “tune up” your programming skills and prepare you for other upper-division networking courses. Third, because you can use the Internet to look for examples, this assignment will help you see just how many network-programming aids are out in the Internet. Finally, having some practical experience will put many of the protocol concepts we learn into perspective. Assignment: You should design a server side that waits for any client to connect. 1- You should design a server side that waits for any client to connect. The server has many text files that clients need. So, it should be able to handle several connections. 2- You should design a client side that needs a specific file from the server. The client send the name of needed file to server. 3- The server read the data for given file and encrypt it using Vigenere Cipher using key “Your first and last name without space”, then send the encrypted file to client. 4- The client receives the encrypted text. 5- The client decrypts the file using the same key and print decrypted data on file (output.txt). 6- Write both client and server programs demonstrating this. Submission: Choose either Java, C or Paython. Your task is to write the server and client programs using UDP and TCP. You will turn in 4 different programs.
-
Server using UDP (file name to turn in : server_udp)
-
Client using UDP ( file name to turn in : client_udp)
-
Server using TCP ( file name to turn in : server_tcp)
-
Client using TCP (file name to turn in : client_tcp)
