Solution Overview

Problem

Existing blockchain networks face challenges in effectively maintaining and verifying the authorization of certificate authorities for smart contracts, ensuring that deployed smart contracts match their audited versions, and efficiently reissuing certificates for upgraded contracts.

Innovation Solution

A blockchain cybersecurity platform employs a tiered certificate authority system with root authorities and certificate authorities to audit and issue certificates, using on-chain audit certificates that are cryptographically secure and expire automatically, ensuring that only authorized entities can issue and reissue certificates, and verifying that deployed smart contracts match their audited versions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a certificate authority system is implemented to audit and issue certificates for smart contracts, then security and verification of smart contract authorization is improved, but device complexity and system overhead increase

Engineering Contradiction:

Improvesmart contract authorization verificationVSAvoidcertificate authority system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The certificate authority system is segmented into hierarchical levels (root certificate authorities and subordinate certificate authorities), allowing distributed verification responsibilities while maintaining centralized trust anchors. This segmentation reduces the complexity burden on any single node while improving overall system reliability for smart contract authorization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Smart contracts include pre-encoded certificate verification logic and authorization parameters before deployment. The verification of certificate authenticity and validity is performed automatically as part of the contract execution process, eliminating the need for separate verification systems and reducing operational complexity.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If certificates are made to expire automatically when smart contracts are updated, then reliability of current certificate validation is improved, but loss of time for certificate reissuance occurs

Engineering Contradiction:

Improvecertificate validity assuranceVSAvoidcertificate reissuance process

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The smart contract includes pre-encoded authorization parameters and certificate verification logic before deployment. When a contract is updated, the new version contains updated authorization parameters that automatically invalidate previous certificates, eliminating the need for manual reissuance processes and reducing time loss.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements automatic feedback mechanisms where certificate validity is continuously checked against the current smart contract version. When a contract update occurs, the system automatically detects the change and invalidates associated certificates, triggering reissuance only when necessary and minimizing time loss through automated workflows.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If multiple root certificate authorities are allowed to coexist, then adaptability and versatility of the certificate system is improved, but difficulty of detecting and measuring authorization conflicts increases

Engineering Contradiction:

Improvecertificate authority system flexibilityVSAvoidauthorization conflict detection

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system introduces intermediary structures (such as trusted anchor certificates and hierarchical validation chains) that mediate between multiple root certificate authorities. These intermediaries provide a standardized verification interface that simplifies conflict detection while maintaining the flexibility to support multiple authorities.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The smart contract verification process includes feedback mechanisms that automatically detect authorization conflicts when multiple root certificate authorities are involved. The contract checks certificate chains and validates authorization parameters against all applicable roots, providing automated conflict detection that reduces measurement difficulty.

Inventive Principle:

Principle #23Feedback

AI summary

In one embodiment, a method includes receiving a request to reissue a certificate for a smart contract, wherein an original certificate was previously issued for the smart contract, determining by a certificate authority that the smart contract is upgradeable and was modified after being issued or the original certificate was revoked, receiving a copy of updated source code of an updated version of the smart contract in a development environment by the certificate authority, determining whether the copy satisfies security criteria by the certificate authority, receiving an indication by the certificate authority that the updated smart contract was deployed on a first blockchain network, determining by the certificate authority that the updated smart contract deployed on the first blockchain network matches the copy of updated source code in the development environment, and issuing a reissue certificate for the updated smart contract by the certificate authority based on the determination.
