Project Description:
Write four programs (in any language that supports fork and pipe, e.g., C and Python).
Each program creates two children processes: The first is “Alice” and the 2nd is “Bob”
Alice and Bob communicate using the following IPC methods:

shared memory
sockets
pipe
shared file

Alice and Bob uses Diffie-Hellman to establish a shared secret to be used for encrypting their communication.

For the purpose of this assignment, assume:

p = 103
g = 101
SA and SB are random numbers between 1 and 100.


For example:


% Qsocket

Qsocket: Using sockets for IPC
Diffie-Hellman Parameters p=103 and g=101
Parent: pid=64588
Alice: pid=64589, my Parent pid=64588

Bob: pid=64590, my Parent pid=64588
Alice Random Secret: 18
Alice Public T: 9
Bob Random Secret: 98
Bob Public T: 58

Bob: Connected to Alice
Alice: Accepted connection from Bob
Bob send to Alice its Public T: 58

Alice send to Bob its Public T: 9


<< Alice Got Bob Public T: 58

Alice-to-Bob Shared Secret: << (93) >>

>> Bob Got Alice Public T: 9

Bob-to-Alice Shared Secret: << (93) >>

Parent: Alice Exited
Parent: Bob Exited
