Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security solutions for cryptocurrencies are difficult for average users to adopt and are vulnerable to phishing attacks, hacks, and other cyber threats due to the anonymous nature of cryptocurrencies and lack of effective safeguards.
Innovation Solution
A system that includes a software application on a computing device configured to store a public cryptocurrency key and a hardware encryption device to securely store the private key, which selectively connects for transaction signing, utilizing multiple authentication processes and secure microcontrollers to protect the private key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If private key is stored on online exchanges or local computers for easy access, then ease of operation is improved, but security against hacking and phishing attacks deteriorates
Solution Approach 1:
The system separates the private key storage function from the transaction interface function by using a dedicated hardware encryption device (separate module) that stores the private key offline, while the computing device handles user interaction and transaction initiation. This physical segmentation prevents online threats from accessing the private key while maintaining ease of use through the computing device interface.
Solution Approach 2:
The hardware encryption device acts as an intermediary between the user and the cryptocurrency network. It mediates the transaction process by receiving transaction requests from the computing device, signing them with the stored private key, and returning the signed transactions. This intermediary role protects the private key from direct exposure to online threats while enabling convenient transactions.
2Reliability
If private key is stored in hardware encryption device offline, then security against online attacks is improved, but ease of operation deteriorates
Solution Approach 1:
The hardware encryption device serves as an intermediary that automates the secure transaction process. Users interact with the computing device interface while the hardware device handles the complex cryptographic operations automatically, making secure offline storage as easy as online storage without requiring users to manually manage key security.
Solution Approach 2:
The hardware encryption device performs self-service by automatically signing transactions with the stored private key when presented with valid transaction requests. This eliminates the need for users to manually export or handle private keys, providing secure offline storage with automated transaction capabilities that maintain ease of operation.
3Reliability
If existing security solutions are implemented, then security measures are improved, but device complexity and difficulty of adoption increase
Solution Approach 1:
The security system is segmented into distinct functional modules: the hardware encryption device for key management and the computing device for user interaction. This segmentation allows each component to be optimized independently, with the hardware device focusing solely on secure key storage and signing operations, reducing overall system complexity while maintaining high security.
Solution Approach 2:
The hardware encryption device is designed as a universal security solution that can work with multiple computing devices and cryptocurrency applications. By providing a standardized interface and consistent security functionality across different platforms, it reduces the complexity of implementing secure cryptocurrency transactions without requiring users to learn different security systems for different devices.
