Solution Overview
Problem
The Internet of Things (IoT) development and adoption are hindered by issues related to connectivity, power supply, and lack of standardization, with proprietary techniques for IoT devices making multi-device adoption burdensome for end users, and short-range wireless technologies limiting data transmission between IoT devices and hubs.
Innovation Solution
A standardized IoT platform with a predefined networking protocol stack, an IoT hub, and an IoT service that enables secure communication channels, data collection, and management, using low-power wireless technologies like Bluetooth LE, and intermediary mobile devices to extend range, along with secure key exchange and encryption methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If proprietary techniques are used for each IoT device, then device functionality can be customized, but device complexity and difficulty of adoption increase
Solution Approach 1:
The patent implements a universal IoT platform that provides standardized networking protocols, infrastructure, and services that can be used across multiple different IoT devices and applications. This allows developers to build diverse IoT solutions using a common foundation, reducing the need for proprietary implementations while maintaining functionality.
Solution Approach 2:
The IoT platform is divided into distinct modular components including networking protocol stack, infrastructure layer, device layer, and application layer. This segmentation allows each component to be developed and optimized independently while maintaining standard interfaces, reducing overall system complexity.
2Use of energy by moving object
If short-range wireless technologies like Bluetooth LE are used, then power consumption is reduced, but communication range is limited
Solution Approach 1:
The patent introduces an intermediary hub device that acts as a relay between low-power Bluetooth LE IoT devices and the wider network. The hub maintains continuous connection with distant devices through higher-power connections while IoT devices use intermittent low-power Bluetooth LE connections, extending effective range without increasing IoT device power consumption.
Solution Approach 2:
The system adds a spatial dimension to communication by introducing intermediate hub nodes that bridge gaps between IoT devices and end destinations. This creates a multi-hop network topology where data can reach beyond direct transmission range through sequential relay points.

AI summary
An apparatus and method are described for secure communication between IoT devices and an IoT service. For example, one embodiment of a system comprises: an Internet of Things (IoT) service to establish communication with an IoT device through an IoT hub or a mobile user device; a first encryption engine on the IoT service comprising key generation logic to generate a service public key and a service private key; a second encryption engine on the IoT device comprising key generation logic to generate a device public key and a device private key; the first encryption engine to transmit the service public key to the second encryption engine and the second encryption engine to transmit the device public key to the first encryption engine; the first encryption engine to use the device public key and the service private key to generate a secret; the second encryption engine to use the service public key and the device private key to generate the same secret; and wherein once the secret is generated, the first encryption engine and the second encryption engine encrypt and decrypt data packets transmitted between the first encryption engine and the second encryption engine using the secret or using a data structure derived from the secret.
