Centralized Key Vault for Secure Transaction Decryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cryptographic networks, maintaining and managing multiple cryptographic keys across various entities increases security risks and complexity, as each entity must coordinate and synchronize keys, making it difficult to monitor activities and ensure compliance with security standards.
Innovation Solution
A centralized key vault system is implemented, where encrypted transaction data is decrypted using a selected decryption technique based on transaction type and device identifier, with private keys stored and managed centrally, reducing the burden on individual entities and enhancing security by minimizing key distribution and management across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each entity maintains and deploys its own cryptographic keys for different transaction types, then each entity can independently manage its keys, but the complexity of key management increases and security risks are amplified across the network
Solution Approach 1:
The patent introduces a centralized key management system that acts as an intermediary between entities and cryptographic keys. This central system generates, stores, and manages all cryptographic keys used across the payment network, eliminating the need for each entity to independently maintain multiple keys. The intermediary system simplifies key management for individual entities while centralizing control to reduce overall network complexity and security risks.
2Productivity
If cryptographic keys are distributed across multiple entities, then each entity can access necessary keys for its operations, but the risk of key compromise increases and monitoring becomes difficult
Solution Approach 1:
The patent extracts the cryptographic key storage and management function from individual entities and consolidates it into a centralized secure key management system. This extraction removes the security vulnerability of distributed key storage while maintaining the ability of entities to process transactions. The central system retains exclusive control over private keys, eliminating the risk of key compromise at individual entities while preserving transaction processing capabilities.
3Adaptability or versatility
If multiple entities maintain separate cryptographic keys, then each entity has autonomy in key management, but compliance monitoring and activity tracking become impossible
Solution Approach 1:
The patent implements a feedback mechanism where the centralized key management system tracks and monitors all cryptographic operations across the network. By maintaining centralized control over key generation, storage, and usage, the system can monitor transaction activities, ensure compliance with security standards, and detect unauthorized operations. This feedback loop enables continuous oversight while entities retain operational autonomy for legitimate transactions.

AI summary
A method for secure decryption may include receiving encrypted transaction data associated with a transaction from a first computing device. The encrypted transaction data may be encrypted using a first public key and may include a transaction type identifier and a device identifier. A first decryption technique may be selected based on the type of the transaction. A first private key identifier may be retrieved from a database based on the first decryption technique and the device identifier. The first private key identifier and the encrypted transaction data may be communicated to a key vault. Decrypted transaction data associated with the transaction may be received from the key vault. First transaction data based on the decrypted transaction data may be communicated to the first computing device. A system and computer program product are also disclosed.
