Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional configuration methods are used for IoT devices, then configuration process is simple, but security is compromised and devices are vulnerable to cyberattacks
Solution Approach 1:
The patent introduces a blockchain network as an intermediary between device manufacturers and IoT devices. The blockchain stores configuration information in immutable blocks that are distributed across multiple nodes, providing a trusted intermediary that enhances security without requiring complex point-to-point verification between each device and manufacturer.
Solution Approach 2:
The patent creates copies of configuration information and distributes them across multiple blockchain nodes. Each node stores an identical copy of the configuration data, ensuring that even if some nodes are compromised, the configuration information remains secure and accessible from other nodes.
2Reliability
If centralized configuration servers are used, then configuration management is centralized, but they become single points of failure and attack targets
Solution Approach 1:
The patent segments the centralized configuration server into multiple distributed blockchain nodes. Instead of a single centralized authority, the configuration information is divided and stored across numerous independent nodes, eliminating the single point of failure while maintaining configuration management capabilities.
Solution Approach 2:
The blockchain network serves multiple functions simultaneously: it acts as a configuration server, a security layer, a distributed storage system, and a verification mechanism. This multi-functionality replaces what would traditionally require separate centralized systems for each function.
3Reliability
If configuration information is stored locally on devices, then access is fast, but it can be tampered with or lost
Solution Approach 1:
The patent implements a feedback mechanism where devices can query the blockchain network to verify the integrity of their local configuration information. The blockchain provides cryptographic proofs and verification mechanisms that allow devices to confirm their configuration has not been tampered with, creating a feedback loop for integrity verification.
Solution Approach 2:
The patent performs preliminary actions by pre-storing configuration information in the blockchain network before devices need it. The configuration data is already validated, signed, and stored in immutable blocks in advance, so when devices need to retrieve or verify configuration, the integrity assurance is already in place without requiring time-consuming verification processes.

AI summary
The present invention relates to the secure configuration of electronic devices, such as for example network-connected "smart" devices and appliances, collectively referred to as "loT devices". A computer-implemented method of secure configuration of at least one electronic device is provided. According to the method, the electronic device connects to a blockchain database; determines from said blockchain database a configuration block comprising block identification data, where the block identification data corresponds to device identification data, stored with the electronic device; obtains configuration information from said configuration block; and using the configuration information, conducts configuration of the electronic device.
