Public Key For Secure Communication TRIZ Cases
- Private-Key Keystores on Provisioned Devices for Credential Revocation
This case uses provisioned-device keystores and revocation logic to protect private keys while managing decentralized credential access.
- Temporary Functionality Enablement for Secure Devices via Expiring HMAC Keys
This case uses unique expiring HMAC keys and trusted-device signatures to enable functions without reusable credentials.
- Peer-to-Peer Certified Document Exchange with Session-Key Encryption
A trusted API and decentralized storage protect certified documents during peer-to-peer exchange without typical file services.
- Exact Homomorphic Encryption Using Quantum-Gate Polynomials
Quantum-gate polynomials enable exact encrypted computation without noise accumulation.
- Group Digital Certificates for Faster Device Onboarding
A group certificate combines device UIDs and public keys to simplify authentication and speed onboarding while reducing storage demands.
- Secure Device Functionality Enablement with Ephemeral HMAC Authentication
A trusted device signs a unique HMAC derived from device data, enabling temporary functionality without reusable cryptographic keys.
- Prime Integer Verification via Linked Lists for Lower-Cost Encryption
Linked-list testing verifies cryptographic primes while limiting computational overhead.
- UAV Security Key with External Private-Key Isolation
A serial-connected key device decrypts UAV media after landing while keeping private keys off the aircraft during flight.
- Ephemeral Authorization Tokens for Encrypted Partner Access
Encrypt nested partner tokens with short expiry to limit replay risk.
- Computation-Cluster Randomness Offloading for Low-End Device Encryption
A computation cluster precomputes random strings so low-end devices encrypt data with less overhead and local randomness generation.
