Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high operational costs and inefficiencies in central certification infrastructures for industrial automation installations, where digital certificates are used for security and authentication, necessitate a more efficient and secure processing of proof of authorization requests.
Innovation Solution
A method utilizing a blockchain-based system where a registration entity checks and forwards proof of authorization requests within a blockchain transaction, leveraging decentralized mining and smart contracts to verify and issue certificates without a central trusted entity, thereby reducing costs and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central certification infrastructure is used to issue digital certificates, then security and authentication are ensured, but operational costs become high and processing efficiency decreases
Solution Approach 1:
The patent segments the certification infrastructure by introducing a registration entity that operates independently from the certification entity. The registration entity handles initial processing and validation of certificate requests, while the certification entity focuses on issuing certificates. This segmentation distributes the workload and improves processing efficiency while maintaining security through the blockchain-based verification system.
Solution Approach 2:
The patent introduces a registration entity as an intermediary between the requesting device and the certification entity. This intermediary processes and validates requests before forwarding them to the certification entity, reducing the direct burden on the central certification infrastructure and improving overall processing efficiency while maintaining security through blockchain verification.
2Reliability
If a central certification entity processes all proof of authorization requests, then security is maintained, but operational costs increase
Solution Approach 1:
The patent segments the certification infrastructure by introducing a registration entity that operates independently from the certification entity. The registration entity handles initial processing and validation of certificate requests, while the certification entity focuses on issuing certificates. This segmentation distributes the workload and improves processing efficiency while maintaining security through the blockchain-based verification system.
Solution Approach 2:
The patent enables self-service through the blockchain system where devices can independently verify certificate validity and process requests through the registration entity. The decentralized nature of blockchain allows devices to perform self-verification without requiring constant intervention from the central certification entity, reducing operational costs while maintaining security.
3Productivity
If blockchain technology is used to process proof of authorization requests, then processing efficiency and cost are reduced, but system complexity increases
Solution Approach 1:
The patent introduces a registration entity as an intermediary that simplifies the interaction between devices and the blockchain system. This intermediary handles the complexity of blockchain transactions and verification processes, presenting a simplified interface to end devices while leveraging blockchain's efficiency for certificate processing.
Solution Approach 2:
The patent uses blockchain to create immutable copies of certificate requests and verification records. Once a certificate is issued, its verification record is stored on the blockchain, allowing any device to verify authenticity without requiring complex validation logic. This copying mechanism simplifies the verification process while maintaining security.

AI summary
Provided is a method for secure processing of an authorization verification request from a unit requesting authorization verification, the authorization verification request being included in a transaction of a block chain, wherein a registration entity performs a check on a block chain data structure and on the transaction protected by the block chain and, in the event of a successful check, forwards the authorization verification request to a certification entity. The authorization verification request is included in a transaction and the registration entity performs a check on a block chain data structure and on the transaction. The transaction and the authorization verification request are protected by the block chain. In particular, the authorization verification request can no longer be altered retrospectively and information that has been transmitted to the registration entity within the context of the authorization verification request is stored in the block chain and protected against manipulation.
