Network watermark
A network communications method utilizing a network watermark for providing security in the communications includes creating a verifiable network communications path of nodes through a network for the transfer of information from a first end node to a second end node; verifying the network communications path of nodes, by the first end node, before communicating by the first end node information intended for receipt by the second end node; and once the network communications path of nodes is verified by the first end node, communicating by the first end node, via the verified communications path of nodes, the information intended for receipt by the second end node; wherein the network watermark represents the verifiable network communications path of nodes.
1. A network communications method comprising:
(a) transmitting a connection request of an application at a first entity in a communication from the first entity to an application at a second entity that traverses a chain of at least two intermediate entities in a network;
(b) collectively creating, at a Link Layer or MAC Layer, an entity pattern representing the chain of intermediate entities as the communication traverses the chain of intermediate entities in the network by each succeeding intermediate entity adding information identifying a MAC address of the succeeding intermediate entity to the communication;
(c) authenticating the connection request at the second entity in the network based on the entity pattern that is collectively created as the communication traverses the chain of intermediate entities in the network; and
(d) after performing the authentication at the second entity, establishing a connection over the chain of intermediate entities between the first entity and the second entity for communicating information between the application at the first entity and the application at the second entity.
2. The network communications method of claim 1 , wherein the entity pattern that is collectively created uniquely identifies each intermediate entity by MAC address.
3. The network communications method of claim 2 , wherein the entity pattern that is collectively created further uniquely identifies the first and second entities by MAC addresses.
4. The network communications method of claim 1 , wherein said step (c) is performed at the Link Layer or MAC Layer.
5. The network communications method of claim 1 , wherein said step (c) is performed at an Application Layer.
