Dual Blockchain Architecture for Secure IoT Data Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices are vulnerable to security threats, such as hacking and Distributed Denial of Service (DDoS) attacks, which can lead to malicious actions and disruptions in industrial and consumer applications, necessitating improved security measures for interconnected networks.
Innovation Solution
Implementing a method that uses two blockchains within an IoT network to ensure legitimate actions are performed by devices, where operational data is stored on one blockchain and action records are stored on another, enabling validation and consensus among devices before actions are executed, thereby preventing unauthorized or malicious actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IoT devices are connected to the Internet to enable communication and data transmission, then the functionality and connectivity of the devices are improved, but the devices become vulnerable to security threats such as hacking and DDoS attacks
Solution Approach 1:
The patent introduces a blockchain network as an intermediary layer between IoT devices and external systems. This blockchain intermediary validates and secures communications, preventing direct hacking attempts while maintaining connectivity. The decentralized nature of the blockchain provides security without compromising the devices' ability to communicate.
2Device complexity
If a single blockchain is used to store operational data and actions, then the system complexity is reduced, but the security and validation reliability are insufficient
Solution Approach 1:
The patent divides the blockchain system into two separate blockchains: one for storing operational data and another for storing actions. This segmentation allows each blockchain to be optimized for its specific purpose and enhances security by isolating different types of data. The separation enables more thorough validation processes without overwhelming system complexity.
3Productivity
If devices are allowed to perform actions autonomously based on operational data, then the productivity and automation level are improved, but the risk of unauthorized or malicious actions increases
Solution Approach 1:
The patent implements a feedback mechanism where actions are recorded on a blockchain and can be validated against operational data. This creates a verification loop that ensures autonomous actions are legitimate and consistent with the device's operational state. The feedback system allows automation while providing security through validation of each action.
Data Source
AI summary
A method and system corresponding to a secure architecture for executing Internet of Things (IoT) device actions using blockchains is described. A network of IoT devices can manage two blockchains. The first blockchain can store operational data, collected from the IoT devices and written to the first blockchain. A second blockchain can be used to store action data.
