    Hello,

    What kind of security is available on the communication between a tart wireless sensor and the Raspberry Pi hat?

    Thank you.

    Hello Greavette,

    There is no encryption on the signal between the sensors and the Tarts Gateway. However the devices use a proprietary protocol that we designed for that communication.

    Please let me know if you have additional questions.

    Thank you for this reply. I don’t think a proprietary protocol provides enough protection for IOT devices. There are lots of reports (like this for example – http://www.csoonline.com/article/3077537/internet-of-things/security-concerns-rising-for-internet-of-things-devices.html) where security at the gateway as well as between the sensor devices is important to user safety.

    Would Tart consider security/encryption between sensors at some point?

    Hi all
    I am interested in tarts devices (FCC, CE etc… great!) very much but I am very concerned about security, knowing that it is not possible to add security by ourselves (no permission to reflash modules).

    Lots of problems could came from this situation:
    1. data secrecy – no, right?
    2. data freshness/replay attack – no, right?
    3. source authentication – no, right?
    4. detect message modification – no, right?

    With all my due respect. Hardware seems very, very attractive to me and to my company but if no security is provided at least it would be interesting to be possible to reflash nodes and where each one could add security services he/she needs. Why not?

    Does anyone knows great alternative hardware like this one?

    Hi Imo,

    I guess you can try looking at monnit sensors. They are more expensive than tarts, but they were the once who, in collaboration with tarts sensors, developed the IR sensors. Try looking at their webpage.
