Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password and user ID driven VPN networks are used for IoT device authentication, then ease of operation is maintained, but security is compromised due to centralized points of failure
Solution Approach 1:
The patent divides the authentication system into multiple independent blockchain channels (authentication channel, data channel, remote channel, security channel) instead of using a single centralized VPN system. Each channel handles specific functions independently, eliminating the single point of failure while maintaining operational simplicity through modular design.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between IoT devices and the network. The blockchain network acts as a decentralized mediator that verifies device identities and manages authentication without requiring traditional centralized VPN servers, thereby improving security while distributing system complexity across multiple nodes.
2Productivity
If IoT devices are densely deployed to enhance scalability and coverage, then productivity increases, but vulnerability to cyber-attacks increases due to more entry points
Solution Approach 1:
The patent implements self-service authentication where each IoT device independently verifies its identity through blockchain-based cryptographic proofs. Devices autonomously authenticate themselves without requiring manual approval or centralized verification, enabling scalable deployment while maintaining security through decentralized identity management.
Solution Approach 2:
The patent incorporates real-time security monitoring and anomaly detection that provides continuous feedback on device behavior. The system monitors authentication patterns, data transmission behaviors, and operational characteristics to detect and respond to potential cyber-attacks, allowing the network to adapt its security measures dynamically as devices are added or compromised.
3Reliability
If centralized authentication servers are used to manage IoT device access, then ease of operation is maintained, but security is compromised due to single points of failure
Solution Approach 1:
The patent creates a universal blockchain-based authentication mechanism that serves multiple functions: device registration, identity verification, access control, and security monitoring. This multi-functional system replaces traditional separate authentication servers while providing enhanced security through decentralization, and maintains ease of operation through standardized blockchain interaction protocols.
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.
