Blockchain Private Key Transaction Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain transactions face security challenges due to the need for secure management and exchange of private keys to validate financial transactions, which is currently reliant on digital signatures and lacks robustness in ensuring transaction security across multiple copies of the blockchain network.
Innovation Solution
A computer-implemented method and system for securing private key transactions within blockchain by generating and securely exchanging private keys for senders and recipients, using an encrypted key generator to create private keys that are exchanged as ownership credentials, and communicating transaction data through a blockchain infrastructure for secure validation and completion of financial transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital signatures are used to validate blockchain transactions, then transaction validation is achieved, but transaction security is insufficient across multiple blockchain copies
Solution Approach 1:
The system segments the security validation process by separating private key generation, secure exchange, and transaction validation into distinct cryptographic operations. Each node independently validates transactions using the exchanged private keys without centralizing security management, thus improving reliability while maintaining distributed architecture
Solution Approach 2:
The patent introduces secure key exchange mechanisms as intermediaries between transaction parties and blockchain nodes. The private keys act as cryptographic intermediaries that enable secure validation without exposing sensitive information, resolving the contradiction between security and complexity
2Reliability
If private keys are exchanged for transaction validation, then transaction integrity is improved, but security management burden increases
Solution Approach 1:
The system implements self-service security management where each participant autonomously generates their own private keys and manages their own cryptographic credentials. This eliminates the need for centralized key management infrastructure, improving transaction integrity through decentralized key ownership while reducing operational burden
Solution Approach 2:
Private keys are generated and exchanged in advance before actual transactions occur. This preliminary cryptographic setup establishes trust relationships beforehand, ensuring transaction integrity without requiring complex security management during the actual transaction execution phase
3Adaptability or versatility
If multiple copies of blockchain are maintained, then network decentralization is achieved, but ensuring transaction security across all copies becomes more difficult
Solution Approach 1:
The patent implements universal private key exchange protocols that function across all blockchain copies independently. The same cryptographic validation mechanism operates consistently on every node, ensuring transaction security reliability while maintaining network decentralization and adaptability
