Nanomaterial Coatings for Circuit Chip Security Against Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to effectively deter advanced techniques such as optical and electron scanning, which can expose and modify proprietary information in electronic devices, leaving them vulnerable to hacking and data extraction.
Innovation Solution
The use of nanomaterial coatings on circuit chips, including nanoshells, silicon-gold nano-materials, Quantum Dot infrared photo detectors, Nanorice, and thermochromic coatings, which absorb light, generate current, or alter properties to prevent identification, reading, or modification of memory locations, and can activate evasive actions like scrambling or destroying critical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional protection methods (passivation layer, laser scanning tools) are used, then the chip structure can be accessed and analyzed, but the proprietary information becomes vulnerable to extraction and hacking
Solution Approach 1:
The patent converts the harmful effect of laser scanning tools into a beneficial detection mechanism. When a laser scanning tool attempts to probe the chip, the nanomaterial coating absorbs the laser energy and generates an electrical current that triggers an alarm or evasive action, thereby transforming the hacking attempt into a security detection event
Solution Approach 2:
The nanomaterial coating serves as an intermediary layer between the external laser scanning tools and the underlying chip circuitry. This intermediate layer absorbs the laser energy before it can reach and probe the sensitive memory locations, preventing direct access to proprietary information
2Object-affected harmful factors
If nanomaterial coatings are applied to block scanning tools, then security is enhanced, but the ability to detect and respond to threats is reduced
Solution Approach 1:
The patent implements a feedback mechanism where the nanomaterial coating detects laser scanning attempts through generated current and triggers evasive actions such as scrambling or zeroizing memory contents. This closed-loop system provides real-time response to threats while maintaining the protective function of the coating
Solution Approach 2:
The nanomaterial coating is self-powered by the laser energy it absorbs from attempted scanning tools. The absorbed laser energy generates electrical current that directly powers the evasive action circuits, eliminating the need for external power sources or complex detection systems
