These programs were developed in python on Raspberry Pis to study the latency and power consumption of various algorithms over a bluetooth connection.
The devices are connected via bluetooth using the pybluez library.
8 encryption algorithms were implemented using the pyca/cryptography library.
Power consumption was measured using UPS HAT by Waveshare.
The client_side and server_side folders contain code designed to run on their respective raspberry pis.
The programs can be run using the client.py file in client_side and server.py in server_side.
The client_side reads data from the provided data.xlsx file, encrypts it row by row, and sends it to the server. The server receives the encrypted message, decrypts it, and sends back the decrypted message.
The server_side has no way of calculating which decryption algorithm to use and only knows to decrypt based off of which encryption algorithm the client_side tells it to use.
