Abstract:
1. A method for transmitting message data from a first node to a second node in a same network having first, second and intermediate nodes, each node in the network being assigned to at least one other node, comprising: enabling access protection for at least some of the nodes in the network such that an access protected node can only receive messages from nodes to which a message was previously sent; determining a sequence from the first node to the second node through at least a first intermediate node and a final intermediate node, the sequence being from the first node to the first intermediate node with the first intermediate node being assigned to the first node, the sequence being from the final intermediate node to the second node with the second node being assigned to the final intermediate node; sending a cancellation message from at least one of the intermediate nodes to a next intermediate node in the sequence until the next intermediate node is the second node, the cancellation message originating in the at least one intermediate node; upon receiving the cancellation message, transmitting a random message from the second node directly to the first node, the random message being separate from the cancellation message; and transmitting the message data from the first node directly to the second node, without the message data passing through any other nodes, after the random message is transmitted from the second node to the first node.
