Unauthorized Memory Use Protection TRIZ Cases
- Voltage Regulator Switch Monitoring for Power Analysis Attack Detection
Monitoring voltage regulator switch activity reveals external power injection used in SPA or DPA attacks, enabling cryptographic shutdown.
- Shared IC Sensor Threshold Isolation for Secure Multi-Core Access
Hardware-filtered threshold registers let multiple IC cores share one sensor while blocking unauthorized threshold changes and saving die area.
- Dynamic Scan Chain Obfuscation Against SAT and Bypass Attacks
Dynamic LFSR-based obfuscation updates scan-chain keys during test access, blocking SAT, bypass, and scan-based attacks on protected circuits.
- Configurable Multi-Chip NoC for Flexible Inter-Chip Communication
Configurable NoCs on separate chips use external and off-chip configuration data to enable flexible inter-chip communication with lower on-chip resource use.
- Masked PUF Error Correction Using a Secure ECC Subsystem
Random masking and stored syndromes let a secure PUF subsystem correct noisy responses through a generic ECC processor without exposing raw secrets.
- Dispersed Storage Verification Scheduling for Data Integrity
Balances internal verification requests with read/write traffic so dispersed storage nodes can check stored blocks without overloading memory access.
- SONOS FPGA Fast Erase Architecture for Tamper Protection
Tamper-triggered simultaneous erase of SONOS FPGA memory cells cuts erase time to one pulse while limiting leakage and blocking data extraction.
- Secure Memory Fault Detection Using Ephemeral Register Counting
Ephemeral register fault counting separates attack-induced faults from SEUs in secure memory without added redundancy, speed loss, or power growth.
- PLD Kill Switch for Clearing Configuration Data on Security Threats
A kill switch clears PLD configuration data and decryption keys when threats are detected, blocking unauthorized access and side-channel attacks.
- Selective Dictionary Encryption for Faster Boot and Data Access
Encrypting only the compression dictionary cuts boot and pagination delays while preserving secure access to compressed digital data.
