Anonymous communications network utilizing bridging connections between broadcast domains

A method comprising:

• receiving a message at a node within a first broadcast domain, the node configured to send the message at least one peer node within the first broadcast domain and to a known bridging node in a second broadcast domain different than the first broadcast domain, the second broadcast domain having two or more bridging nodes;
• causing the node to send the messages to the at least one peer node so that multiple instances of the message are passed through the first broadcast domain;
• performing a pseudorandom function on the message to determine a subset of the two more bridging nodes of the second broadcast domain that will receive the message;
• and
• based on the known bridging node being in the subset, sending the message to the known bridging node.

An apparatus, comprising:

• a network interface configured to communicate with at least one peer node within a first broadcast domain and with a known bridging node in a second broadcast domain different than the first broadcast domain, the second broadcast domain having two or more bridging nodes;
• and
• a processor coupled to the network interface and configured to:
• receive a message within the first broadcast domain;
• send the messages to the at least one peer node so that multiple instances of the message are passed through the first broadcast domain;
• perform a pseudorandom function on the message to determine a subset of the two more bridging nodes of the second broadcast domain that will receive the message;
• and
• based on the known bridging node being in the subset, send the message to the known bridging node.
