Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If memory is utilized to store secure data, then data storage capability is improved, but vulnerability to hacking techniques increases
Solution Approach 1:
The patent combines cryptographic processing logic and secure data storage memory into a single integrated circuit device, where the memory is physically embedded within the secure element. This merging ensures that even if the memory is accessible, the cryptographic keys and algorithms required to exploit vulnerabilities are not separately accessible, reducing hacking vulnerability while maintaining storage capacity.
Solution Approach 2:
The patent implements a nested structure where the memory component is embedded within the secure element, which itself is contained within the integrated circuit device. This nesting creates multiple layers of physical and logical protection, allowing the memory to store secure data while being protected by the surrounding security mechanisms including cryptographic processing units and access control logic.
2Reliability
If cryptographic algorithms with high complexity are used, then security against breaking is improved, but computational requirements increase
Solution Approach 1:
The patent integrates cryptographic processing logic directly within the secure element alongside the memory, allowing high-complexity cryptographic operations to be performed locally without requiring external computational resources. This merging enables strong cryptographic security while reducing the need for external computational power by performing all cryptographic functions within the self-contained secure element.
3Object-affected harmful factors
If physical countermeasures are implemented, then resistance to physical hacking is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple security functions including cryptographic processing, secure memory storage, and physical countermeasures into a single integrated secure element. This merging provides comprehensive physical hacking resistance through unified protection mechanisms while avoiding the increased complexity that would result from implementing separate security devices for each function.
Solution Approach 2:
The secure element is designed as a universal security component that simultaneously performs cryptographic operations, stores secure data, and implements physical countermeasures. This multi-functionality provides comprehensive security protection without increasing overall device complexity, as all security functions are integrated into a single standardized component.

AI summary
An electronic hardware wallet for conducting cryptocurrency transactions, blockchain transactions, or other secure communications is embodied on a monolithic integrated circuit (IC) die supported on a single substrate. The monolithic semiconductor device can include a non-volatile data store for storing application software executable by the multi-core processor, and the secure element can include a secure data store for storing secret data (e.g., a private key) for use in a secure electronic transaction. In some embodiments, the secure element can include hardware logic embodying a cryptocurrency algorithm associated with executing the secure electronic transaction and can have a limited and selective communication bus between the secure element and the multi-core processor. The electronic hardware wallet can communicatively couple with one or more other devices to facilitate a multi-party computation (MPC) algorithm for authenticating the cryptocurrency algorithm and validating the secure electronic transaction.
