ABSTRACT

For most of the cryptography algorithms, randomness plays a vital role. But generation of pure random number is impossible in classical computer. Even for generating decent random numbers it needed a random seed. But since the seed is a number in source code or algorithm to generate seed which is also in source, it can be revealed to hacker if the system is compromised. Which made possible to predict all the random numbers the computer will generate by the hacker. So, to solve this issue we introduce quantum computer to create a true randomness using its superposition capability.

But quantum machines are not accessible to all the computers, especially to clients. So, we found that it is possible to generate a pure random number on client side with the help of quantum computer on server side using Diffie Hellman Key Exchange, even through un-encrypted channel without any compromise.

2. Run server script

python server_cli.py

(venv) ~/nk/mainproj >>> python server_cli.py -h
usage: server_cli.py [-h] [-1 | -2] [-g] [-s] [-p]

options:
  -h, --help  show this help message and exit
  -1          Use qmachine1
  -2          Use qmachine2
  -g          For GUI
  -s          Show Qcircuit
  -p          Plot Qcir result

3. Run client script

python client_cli.py

4. Start messaging from client

(venv) ~/nk/mainproj >>> python client_cli.py                                   
Shared Key : b'\x04O\xceT\xfb\xd29'
Message to server : Hi
Response from server : Bye
Message to server : Exit
(venv) ~/nk/mainproj >>> 

(venv) ~/nk/mainproj >>> python server_cli.py
