Blackout Comms Public Channels

A Blackout Comms public channel is an unstructured group of mesh-connected devices that securely communicate and work together as a decentralized mesh network. It doesn't have as many features as a private cluster, but allows an unlimited number of device in the group. Security in a public channel is highly dependent on how well the shared keys are protected.

Sending & Receiving Messages

  • Decentralized mesh cache helps deliver packets

  • All messages are broadcasts to the channel

  • Confirmation of acceptance/rebroadcast

  • Broadcasts can optionally be displayed on nodes

Location Awareness & Sharing

  • Location can be sent along with any broadcast

  • The location marker (if sent) remains with that broadcast message as it carries forward to other devices

  • View location, speed, and heading included in any broadcast​

Limitations

  • Unlimited communicators and links

  • DM delivery attempts can continue for up to 24 hours
    Broadcast messages can continue to propagate for up to 2 hours

  • Your cluster’s security is only as good as the weakest
    link in those who have/know the cluster credentials

  • There is no neighbors screen

  • Unlike private clusters, there is no chain of trust (just secret keys) and no enforced identities

Security

  • Channel ID/creds can be manually entered into a communicator, or “pushed” from another communicator.

  • Channel info must be pushed from communicators to nodes

  • Broadcasts are symmetrically encrypted

  • All transmissions are digitally signed using channel keys
