Locker Device

The device is an Arduino Uno, with HC-05 Bluetooth module, to simulate a locker, which must be opened or closed if the user is authorized

See https://github.com/DistributedSystemsProject/AuthorizationServer to understand the used protocol.

In the ECC branch there is the device code, using Elliptic-curve cryptography (ECC): https://github.com/DistributedSystemsProject/LockerDevice/tree/ecc

Requirements

Install the external libaries:

1. Base64 from https://github.com/agdl/Base64
2. AES-128 Enc/Dec from https://github.com/DavyLandman/AESLib
3. SHA-256 Hmac from https://github.com/daknuett/cryptosuite2
4. JSON from https://github.com/bblanchon/ArduinoJson

Usage

Connect the Bluetooth module, on these Arduino pins:

• A2 // PIN bluetooth power
• A3 // PIN bluetooth state
• A4 // PIN bluetooth reception
• A5 // PIN bluetooth transmission

Run the code on your device.

When the operation is successful, the code prints on the Serial Monitor, the following string: "Operation DONE!"

Known Issues

The code works only with Arduino AVR Boards 1.6.21. If you update to a newer version, the program can't start (only tested with Arduino IDE on Windows 10).
