Security Gateway Architecture for Centralized Digital Currency Ledgers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed ledger technology (DLT) is not suitable for implementing national digital currencies (NDCs) due to safety concerns when interfacing with the public over the internet, necessitating a centralized tracking system that must be secure from various threats.
Innovation Solution
A centralized system (CS) for tracking NDCs is designed with a security gateway system as an interface, incorporating ID management, ledger storage, artificial intelligence, and memory systems, along with robust safety measures such as multi-factor authentication, anti-spoofing, and comprehensive software sub-applications to ensure secure and compliant packet processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DLT is used for NDC implementation, then decentralization and consensus are achieved, but safety and security against public internet threats are compromised
Solution Approach 1:
The patent introduces a centralized security gateway system as an intermediary between the public internet and the NDC ledger system. This gateway filters and validates all incoming transactions before they reach the ledger, acting as a protective barrier that enables centralized control to maintain safety while allowing decentralized transaction processing
2Reliability
If centralized tracking is implemented for NDCs, then security and safety are improved, but system complexity increases
Solution Approach 1:
The patent segments the NDC system into distinct functional modules: a centralized security gateway system for security operations, a separate ledger system for transaction recording, and interface layers for communication. This segmentation allows each component to be optimized independently, managing overall system complexity while maintaining high security standards
3Reliability
If comprehensive security measures are implemented, then unauthorized access is prevented, but processing speed and efficiency are reduced
Solution Approach 1:
The security gateway system performs preliminary validation, filtering, and authentication of transactions before they are submitted to the ledger for final processing. By pre-processing security checks and rejecting invalid transactions early, the system prevents unnecessary processing delays later in the transaction flow, maintaining both security and processing efficiency
Data Source
AI summary
A centralized tracking system includes a security gateway system and a main memory system. The security gateway system interfaces with the public over the internet at an internet protocol address, and comprises a memory that stores packets received from the public over the internet and a processor that executes a plurality of algorithms to impose safety checks on each packet received from the public. The main memory system is shielded from the public by the security gateway system, stores records for the centralized tracking system, and receives updates to the records from the security gateway system once instructions from the public pass the safety checks.
