Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptography systems are implemented for digital wallet security, then security is improved, but system complexity increases
Solution Approach 1:
The patent introduces HSMs as intermediary devices that specialize in cryptographic operations. These HSMs act as mediators between the digital wallet system and cryptographic key management, handling key generation, storage, and cryptographic operations externally. This allows the main wallet system to benefit from enhanced security without directly implementing complex cryptography, thus resolving the contradiction between improved security and reduced system complexity.
2Reliability
If HSMs are used for key management, then security is improved, but integration difficulty increases
Solution Approach 1:
The patent implements a universal API interface that standardizes interactions with HSMs across different digital wallet implementations. This multi-functional API layer provides a consistent method for key generation, encryption, decryption, and signing operations regardless of the underlying HSM vendor or specific cryptographic algorithms used. This universality simplifies integration by providing a single standardized interface that works with multiple HSM implementations, resolving the contradiction between enhanced security and ease of integration.
3Reliability
If tokenization is implemented, then privacy is improved, but processing complexity increases
Solution Approach 1:
The patent implements tokenization by creating simplified proxy representations (tokens) of sensitive cryptographic data. Instead of directly processing and transmitting actual private keys or sensitive information, the system creates token copies that represent these values. These tokens can be safely transmitted, stored, and processed without exposing the underlying sensitive data. The HSM manages the mapping between tokens and actual cryptographic values, enabling privacy protection while keeping the processing logic relatively simple and centralized in the secure hardware module.

AI summary
Systems and methods for implementing a secure digital wallet processing system. An example method comprises: receiving, by a computer system, a distributed ledger transaction and a public address; retrieving, from a key management system, a private key corresponding to the public address, wherein the key management system comprises a hardware security module (HSM) that generated the public address from the private key; signing the distributed ledger transaction by the private key; and providing the signed distributed ledger transaction to a distributed ledger.
