Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional VPN networks are used for IoT device authentication and access control, then device connectivity is established, but security vulnerability increases due to centralized authentication points and password-based mechanisms
Solution Approach 1:
The patent divides the authentication and security management into separate blockchain channels: an authentication channel for device registration and verification, and a security channel for intrusion detection and anomaly monitoring. This segmentation eliminates the need for a single centralized authentication point, distributing security functions across multiple independent blockchain instances, thereby improving reliability while reducing the complexity of any single authentication mechanism.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary mechanism between IoT devices and the central management system. Instead of direct password-based authentication, devices use cryptographic identities verified through the blockchain network. The blockchain acts as a trusted intermediary that mediates authentication requests, data sharing, and security monitoring, eliminating vulnerabilities in traditional VPN authentication while maintaining connectivity.
2Difficulty of detecting and measuring
If centralized security monitoring is implemented, then intrusion detection capability is improved, but system vulnerability increases due to single point of failure
Solution Approach 1:
The patent separates intrusion detection functions into distributed blockchain nodes rather than a centralized monitoring system. Each blockchain node independently monitors and records security events, creating a distributed detection network. This eliminates the single point of failure while maintaining comprehensive intrusion detection capability across the entire IoT network.
Solution Approach 2:
The blockchain network performs self-monitoring and self-verification of security events. Each transaction and data exchange is automatically recorded and verified by the distributed ledger, eliminating the need for external centralized security monitoring. The system monitors itself through its own distributed architecture, improving both detection capability and reliability simultaneously.
3Reliability
If multiple blockchain channels are implemented for separate authentication, data, and security functions, then system reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a multi-chain architecture where each blockchain channel serves multiple purposes: the authentication channel handles device registration and verification, the data channel manages data sharing and transactions, and the security channel performs intrusion detection and anomaly monitoring. By making each chain multi-functional rather than creating separate systems for each function, the patent improves reliability through redundancy while minimizing the increase in device complexity.
Data Source
AI summary
Systems and methods for building a trusted network of devices with intrusion detection system (IDS) using blockchain IoT (BIoT) technology are provided. The method includes registering an IoT device on a plurality of blockchain network channels. The plurality of blockchain network channels include an authentication channel, data channel, remote channel, and security channel connected to corresponding servers to perform dedicated operations such as device authentication, data management, remote operation/access control, and intrusion detection. On successful authentication, the IoT device is allowed to access, store and retrieve data stored on the blockchain. The blockchain ledger is updated after each data transaction and a new wallet identity or encrypted keys for the IoT device are issued after each transaction. The method further includes receiving an operational instruction from a front-end device and authenticating from the blockchain record, the wallet identity, user permissions and validity of operation's parameters based on an organization's policies.
