Key Distribution For Secure Communication TRIZ Cases
- Autonomous Driving Recorder Secure Logging for Tamper-Proof Data
A secure world, authenticator, and trigger-based logging protect autonomous driving records from tampering for reliable accident review.
- Quantum Key Distribution Encoding With Time-Bin Phase Modulation
Time-bin phase and intensity modulation helps QKD keep strong optical signals while making encoded information harder to extract from scattered radiation.
- Physical Key Secure Enclave for Delegated Vehicle Access
A secure enclave in a physical key derives limited-use keys for phones, enabling flexible vehicle access without phone-side secure hardware.
- Quantum Key Encoding with Time-Varying Pulse Profiles
Time-dependent intensity and phase modulation encodes QKD pulses with weak distinguishability, improving shared-key security against leakage.
- EV Charging Authorization via Certificate-Based Privacy Protection
A clearing-house model authenticates EV charging with vehicle certificates, cutting personal data exposure, cost, and provisioning complexity.
- Tire Monitoring Network Key Exchange With Broadcast Cryptographic Parameters
Broadcast key exchange lets tire monitoring devices form shared keys securely while cutting message traffic and avoiding pre-installed keys.
- Vehicle ECU Key Verification Using an External Distributed Ledger
Periodic ECU key checks against an external distributed ledger help prevent key falsification and secure in-vehicle communications.
- SNSPD Pixel Trench Layout for Thermal Crosstalk Isolation
Concave trenches between SNSPD pixels lengthen the heat path, suppress thermal crosstalk, and preserve detection efficiency and rates.
- Neutral Vehicle Data Management With Pseudonymized Linking
Pseudonymized vehicle and driver identifiers let neutral servers use ADAS event data while preserving privacy and lawful relinking.
- Digital Key Authentication via Secure Element in Power-Off State
Pre-authenticated identity data stored in a secure element lets a digital key remain verifiable even when the terminal is powered off.
