System and Method for Subscription-Based IOT Communication Security - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240333495 titled 'System and Method for Subscription-Based IOT Communication Security

Simplified Explanation

The patent application describes a method for subscription-based IoT communication security in industrial Internet of Things (IIoT) devices. This method involves generating keys, deploying them to devices, encrypting messages, and decrypting them based on usage constraints.

• Receiving a subscription request for a service from an edge device
• Generating master key and key parameters for the subscription request
• Deploying key parameters to the IIoT device
• Generating a private key with constraints based on the master key, key parameters, device ID information, and usage constraint parameter
• Encrypting messages at the device based on key parameters, device ID, and current usage parameter
• Decrypting messages using the private key with constraints when the current usage parameter is valid for the usage constraint parameter

Original Abstract Submitted

various embodiments of the teachings include a method for subscription-based iot communication security. an example method includes: receiving a subscription request for a service of an industrial internet of things (iiot) device from an edge device; generating a master key and key parameters for the subscription request; deploying the key parameters to the iiot device; generating a private key with constraint based on the master key, the key parameters, identifier (id) information of the iiot device, and a usage constraint parameter for subscription range, and sending the private key with constraint to the edge device; encrypting, at the device, a message based on the key parameters, the id information of the device, and a current usage parameter, and sending an encrypted message to the edge device; and decrypting it using the private key with constraint when the current usage parameter of the message is valid for the usage constraint parameter.
