Digital Identity Key Management for Complex Asset Credentials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in managing digital currency keys due to their complexity and irregularity, and the proliferation of smart products leads to scattered accounts, causing inconvenience and security risks in asset management.
Innovation Solution
A key management method and apparatus that utilizes a digital identity system, where a character decryption key is acquired based on identity authentication, allowing users to manage assets without memorizing cumbersome keys, and employs encryption and multiple layers of authentication to secure the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manage digital currency keys directly, then security control is maintained, but user convenience deteriorates due to complex key memorization
Solution Approach 1:
The patent introduces a digital identity system as an intermediary between users and digital currency keys. The digital identity contains encrypted key information that can be decrypted under controlled conditions, eliminating the need for users to directly manage complex keys while maintaining security through multi-factor authentication and encrypted storage mechanisms
2Adaptability or versatility
If users manage multiple smart product accounts, then functionality increases, but management complexity and security risks increase
Solution Approach 1:
The patent creates a universal digital identity system that can manage multiple types of assets including digital currencies, smart product accounts, and other electronic assets through a single interface. The system uses standardized authentication protocols and encrypted storage structures that work across different product types, reducing management complexity while maintaining broad compatibility
3Reliability
If traditional key storage methods are used, then simplicity is maintained, but security against leakage and loss deteriorates
Solution Approach 1:
The patent implements a nested encryption structure where digital identities contain encrypted key information, which itself is protected by multiple layers of encryption including device-specific keys and authentication credentials. This nested structure enhances security by distributing trust across multiple layers while simplifying user interaction through a single digital identity interface

AI summary
Disclosed are a key management method and a key management apparatus. The method includes: after confirming that a user logs into a digital identity through a first identity authentication mode, acquiring a first character decryption key corresponding to a first character in at least one character of the digital identity; and decrypting, based on the first character decryption key, an encrypted target key stored in the digital identity to obtain a target key, where the target key is used to manage an asset corresponding to the first character. Based on the technical solutions provided in the present application, a user can log into a digital identity through existing identity information and implement asset management without memorizing a cumbersome and complicated key, which provides great convenience for the user.
