Secure Communication between Client and Multi-Processing Server using Socket Programming

Secure Communication between Client and Multi-Processing Server using Socket Programming 100 points Due: Friday, November 17,11:59pm Socket Programming Problem Description The purpose of this programming assignment is to practice with Socket Programming. In this project, you would be required to write "C" programs for "Client" and "Server" using socket programming to implement secure communication between clients and a multi-processing server. On Server side, use multi-processing, such that Server can handle requests from more than one client, using one process to handle each client's request. A multi-processing server creates a new process for each communication it accepts from a client. In this programming assignment, you will be asked to implement a simple client/server program, using connection-oriented communication (socket programming using TCP) 1. Client: Input a string (e.g. system time, IP address) called "A's data package" hereafter Client calculates the hash value as: hash(A's data package) - message digest Create "Digital Signature" (by encrypting the message digest using the StringEncoder.c program provided at the end of this document) as: Encrypt (message digest) digital signature
