Edge computing for internet of things security with blockchain authentication

A device comprising:

• a processor configured to:
• receive, by a first blockchain node in a first multi-access edge computing (MEC) device and via a first Radio Access Network (RAN), a message from a first Internet of Things (IoT) device to a second IoT device, wherein the first MEC device is located in a first MEC network;
• identify, by the first blockchain node in the first MEC device, a second blockchain node associated with the second IoT device based on information stored in a blockchain associated with the first blockchain node and the second blockchain node, wherein the blockchain stores routing information that identifies that the second IoT device is reachable via the second blockchain node;
• and
• send, by the first blockchain node in the first MEC device, the message to the identified second blockchain node in a second MEC device, wherein the second MEC device is located in a second MEC network associated with a second RAN servicing the second IoT device.

A non-transitory computer-readable memory device storing instructions executable by a processor, the non-transitory computer-readable memory device comprising:

• one or more instructions to receive, by a first blockchain node in a first multi-access edge computing (MEC) device and via a first Radio Access Network (RAN), a message from a first Internet of Things (IoT) device to a second IoT device, wherein the first MEC device is located in a first MEC network;
• one or more instructions to identify, by the first blockchain node in the first MEC device, a second blockchain node associated with the second IoT device based on information stored in a blockchain associated with the first blockchain node and the second blockchain node, wherein the blockchain stores routing information that identifies that the second IoT device is reachable via the second blockchain node;
• and
• one or more instructions to send, by the first blockchain node in the first MEC device, the message to the identified second blockchain node in a second MEC device, wherein the second MEC device is located in a second MEC network associated with a second RAN servicing the second IoT device.
