Security analysis of radio water meters

Résumé

Smart meters are nowadays everywhere, and are used to monitor energy and water consumptions. There are many different devices, from different manufacturers, and each of them need to send information to a collecting station/device. Thus the encryption of the said data is an important stake. Water meters in particular rely on local radio communication, transmitting water consumption records to local base stations. There were few security audits on those devices, especially because they rely on proprietary radio protocols, while the data they transmit can be sensitive and personal. This work is about learning, understanding and reversing radio protocols, to notice that sometimes security measures may be unsatisfactory, mainly because of how the encryption mechanisms are implemented.
