Internal/Peripheral Component Protection TRIZ Cases
- Networked Device Risk Assessment via Passive Protocol-Aware Traffic Analysis
A programmable switch mirrors network packets for protocol-aware risk checks, exposing weak credentials and outdated protocols.
- Randomized Keypad Transformation for Snooping-Resistant Authentication
An RTA changes keypad mappings each session, helping users resist visual snooping and keylogging without added authentication hardware.
- System-on-Chip DMA Controllers with Hardware Routing by Security Level
A hardware routing circuit assigns secure and non-secure DMA requests, reducing interrupts and blocking unauthorized memory access.
- Mobile Terminal Control Through Virtual SIM After SIM Removal
A stored virtual SIM remains active after physical SIM removal, enabling positioning, locking, and data clearing.
- TEE Input Verification Engine for Secure Binary Translation
A trusted execution environment verifies translated binaries and user inputs while keeping sensitive data away from external apps.
- Secure Keyboard Auto-Locking via Mobile Device RF Range
RF range tracking uses a paired mobile device to disable unattended keyboard input, restoring access on return or authenticated override.
- Entropy Driver Detection for Ransomware-Resilient Client File Backups
An entropy driver compares changed files with filetype baselines, while isolated volumes and secondary backups limit ransomware corruption.
- 3D Printer DRM for Controlled Design Distribution and Printing
Incremental streaming and post-use slice deletion let licensed printers distribute 3D designs without exposing reusable source files.
- Cryptocurrency hardware wallet on monolithic chip with common physical countermeasures and secure memory
Physical attacks and exposed links challenge wallets; this case combines a secure element, resistive memory, and physical countermeasures.
- Remote Device Data Upload via Pre-Stored User Access
A management server mediates device uploads to external storage, reducing processing effort while preserving authorized access.
- Hardware User Interface Firewall for Pixel-Level Security Separation
A hardware firewall separates secure and non-secure screen regions, controlling processor access without requiring separate devices.
- Beacon-Enabled Distribution Item Tracking for Misrouting Detection
Event-driven beacon activation tracks distribution items in transit, balancing location precision with lower power use until delivery.
- Tracking Device Identity Verification for Theft–Stalker Protection
This case uses user-equipment identity verification to switch tracking devices between covert theft tracking and stalker alerts.
- Encrypted Algorithm Obfuscation to Prevent Plaintext Exposure
Obfuscate algorithms while processing ciphertext to prevent plaintext exposure.
- Speculative Execution for Security-State Transition Pipelines
This case issues instructions before security state transitions finish, then validates requirements at completion to limit flushes.
- Muscle/Memory Wire Component Locks with BIOS Access Control
BIOS authentication applies voltage to muscle wire, unlocking components for authorized repair while preserving locked access otherwise.
- Control Device Authentication Chain for Lower Host Load
Sequential chips relay authentication data so the host device can verify multiple chips with fewer direct interactions.
- Host Device Multi-Chip Authentication Chaining to Reduce Interaction Load
This case chains authentication data across multiple chips, reducing host-device interactions while supporting total chip verification.
