Authorization management in an internet of things (IoT) network
In an approach, a processor receives, at an edge node, a message from an IoT device associated with the edge node, the message being embedded with at least one non-fungible token (NFT) and each of the at least one NFT representing a corresponding authorization associated with the IoT device. A processor retrieves, at the edge node, the at least one NFT from the received message. A processor validates, at the edge node, the received message based on the retrieved at least one NFT. A processor, responsive to validating the received message, forwards, by the edge node, the received message to a center node associated with the edge node.
1. A computer-implemented method comprising:
receiving, at an edge node, a message from an Internet of Things (IoT) device associated with the edge node, the message embedded with a first non-fungible token (NFT), wherein:
the IoT device is authorized to provide a plurality of different types of sensor data; and
each type of sensor data corresponds to a different NFT of a plurality of NFTs created for the IoT device;
retrieving, at the edge node, the first NFT from the received message;
validating, at the edge node, the received message based on the retrieved first NFT; and
responsive to validating the received message, forwarding, by the edge node, the received message to a center node associated with the edge node.
2. The computer-implemented method of claim 1 , wherein the plurality of NFTs are stored on a blockchain.
3. The computer-implemented method of claim 1 , wherein the plurality of NFTs are provided to the IoT device upon a registration phase of the IoT device.
4. The computer-implemented method of claim 1 , wherein the first NFT is associated with a unique identifier of the IoT device.
5. The computer-implemented method of claim 1 , wherein the corresponding authorization comprises information about a resource the IoT device is authorized to provide.
6. The computer-implemented method of claim 1 , wherein:
the message is further signed with a private key associated with the IoT device; and
the validating the received message further comprises validating, at the edge node, the received message further based on a public key corresponding to the private key associated the IoT device.
7. A computer program product comprising:
one or more computer readable storage media; and
program instructions stored on the one or more computer readable storage media to perform operations comprising:
receiving, at an edge node, a message from an Internet of Things (IoT) device associated with the edge node, the message embedded with a first non-fungible token (NFT), wherein:
the IoT device is authorized to provide a plurality of different types of sensor data; and
each type of sensor data corresponds to a different NFT of a plurality of NFTs created for the IoT device;
retrieving, at the edge node, the first NFT from the received message;
validating, at the edge node, the received message based on the retrieved first NFT; and
responsive to validating the received message, forwarding, by the edge node, the received message to a center node associated with the edge node.
8. The computer program product of claim 7 , wherein the plurality of NFTs are stored on a blockchain.
9. The computer program product of claim 7 , wherein the plurality of NFTs are provided to the IoT device upon a registration phase of the IoT device.
10. The computer program product of claim 7 , wherein the first NFT is associated with a unique identifier of the IoT device.
11. The computer program product of claim 7 , wherein the corresponding authorization comprises information about a resource the IoT device is authorized to provide.
12. The computer program product of claim 7 , wherein:
the message is further signed with a private key associated with the IoT device; and
the validating the received message further comprises validating, at the edge node, the received message further based on a public key corresponding to the private key associated the IoT device.
13. A computer system comprising:
a processor set;
one or more computer readable storage media; and
program instructions stored on the one or more computer readable storage media to cause the processor set to perform operations comprising:
receiving, at an edge node, a message from an Internet of Things (IoT) device associated with the edge node, the message embedded with a first non-fungible token (NFT), wherein:
the IoT device is authorized to provide a plurality of different types of sensor data; and
each type of sensor data corresponds to a different NFT of a plurality of NFTs created for the IoT device;
retrieving, at the edge node, the first NFT from the received message;
validating, at the edge node, the received message based on the retrieved first NFT; and
responsive to validating the received message, forwarding, by the edge node, the received message to a center node associated with the edge node.
14. The computer system of claim 13 , wherein the plurality of NFTs are stored on a blockchain.
15. The computer system of claim 13 , wherein the plurality of NFTs are provided to the IoT device upon a registration phase of the IoT device.
16. The computer system of claim 13 , wherein the first NFT is associated with a unique identifier of the IoT device.
17. The computer system of claim 13 , wherein the corresponding authorization comprises information about a resource the IoT device is authorized to provide.
