Secure extensible wireless communication with iot devices

A method of establishing an extensible, multi-hop, protected channel of wireless communication between a base node and a field IoT device, within a system of a plurality of constituent IoT devices, said method comprising:

• configuring, in each of the plurality of constituent IoT devices, a hardware and/or software based secure-hop (SH) component, said SH component capable of receiving messages from other constituent IoT devices, said SH component further capable of broadcasting messages to other constituent IoT devices within wireless communication range, each broadcast between constituent IoT devices comprising a communication hop, each communication hop involving a sending device that is sending a message, and at least one receiving device that is receiving the message, said SH component configured to emit a masking signal substantially simultaneous to each communication hop, said masking signal comprising electromagnetic waves of a particular pattern of constant or varying frequency, wavelength, and amplitude, said pattern introducing electromagnetic noise into an environment of the communication hop, said noise rendering the message being transmitted across the communication hop unintelligible to an entity outside the system, and said SH component further configured to enable the receiving device to recognize and decipher said particular pattern of the masking signal, such that the receiving device is able to filter the masking signal out of the noisy environment, and retrieve the message transmitted across the communication hop;
• arraying, a plurality of constituent IoT devices in a chain-like fashion between the base node and a field IoT device, such that each constituent IoT device is within wireless communication range of at least one other constituent IoT device, said array extensible for coupling at least one additional IoT device to extend the chain to the additional IoT device;
• generating, by at least one field IoT device, a secure message to communicate with the base node, said message considered secure when the message has been determined by the device as requiring to be shielded from outside interception;
• and
• sending, by the field IoT device, the secure message to the base node via the chain of IoT devices, in a manner that is protected from being intercepted, said secure message hopping from one constituent IoT device in the chain to the next using the SH component, the SH component further protecting each hop of the secure message from interception by emitting a masking signal.

• such that the first IoT device is able to communicate wirelessly with the wireless-capable node in the first area, and the first IoT device is also able to communicate wirelessly with at least one other isolated IoT device in the heretofore wireless communication-lacking second area;
• the system further comprising an emergency-communication component built in to each IoT device, said component comprising software and/or hardware, and said component controls its host IoT device and directs the flow of communications in the IoT device;
• wherein the emergency-communication component of an isolated IoT device directs the isolated IoT device to send a wireless message to the first IoT device, and the emergency-communication component of the first IoT device relays the message by directing the first IoT device to receive the message and subsequently broadcast it the wireless-enabled node that is coupled to the communication network, said message effectively hopping from the isolated IoT device to the first IoT device, and hopping once again from the first IoT device to the wireless-enabled node;
• and
• wherein said system is extensible by deploying at least one additional IoT device in the second area, each additional IoT device within the wireless communication range of at least one other IoT device, each additional IoT device, under the direction of each device's emergency-communication component, functioning as a router to further extend, distal from the first area, the range of wireless communication with the wireless-enabled node, each device relaying communication from one to the other in a chain fashion, until the isolated IoT device farthest from the first area is reached, at which point said farthest isolated IoT device is enabled to communicate with said communication network in the first area via the chain of IoT devices, under the direction of each device's emergency-communication component, and the farthest isolated IoT device sends a wireless message to the communication network.

A system comprising constituent IoT devices, that establishes a secure channel of communication between its constituent IoT devices, said system comprising:

• a plurality of constituent IoT devices, each of said plurality of constituent IoT devices comprising the ability to communicate wirelessly with other IoT devices within the system in an intra-system communication, said intra-system communication comprising a sending device that is transmitting a message and a receiving device which is the target recipient of said message;
• each IoT device comprising a secure-communication (SC) component, said SC component comprising hardware and/or software, wherein said SC component emits a masking signal substantially simultaneous to an intra-system communication;
• said masking signal comprising electromagnetic waves of a particular pattern of constant or varying frequency, wavelength, and amplitude, said pattern introducing electromagnetic noise into a system environment, said noise rendering a substantially simultaneous intra-system communication between constituent IoT devices unintelligible to an entity outside the system, said outside entity that is attempting to illicitly obtain data by intercepting intra-system communications absent proper consent;
• and
• said SC component further comprises the capability, in the receiving device in an intra-system communication, to recognize and decipher said particular pattern of a masking signal, such that the receiving device is able to filter the masking signal out of the noisy environment, and retrieve the intended message of the intra-system communication.
