open communication between keypad, RFID Scanner and client #4

The communication between RFID scanner -> client and keypad -> client are not encrypted. An attacker can simply record the communication and login with the wrong identity.

To protect the communication it need to be encrypted.

As encryption has only limited impact in the event of physical attacks on hardware I suppose to implement intrusion detection to detect tinkering with the devices. If a possible attack is detected the corresponding device should be treated as unsafe until marked as safe by a trusted person.
