I'm curious what kind of eavesdropping is feasible on this band. It's not clear if there's encryption built in, especially if low power, and the long distances make for some attractive triangulation opportunities too.
You can further encrypt your own payloads to keep them extra secret from us too.
If by the manufacturer, then it is potentially a security and privacy concern.
There's a whole process to how the secret for each device is created. That secret is used to ensure helium connectivity is safe. You can then securely implant your own secret into a chip we use and that secret can be used to encrypt your payload. Helium never has to know what you are sending. We just need to know where it's going so we can get it there for you.
We'll be posting more docs on this in the coming weeks and months. Feel free to shoot me an email if you want to chat more before they are available.
