Multiple Keys/Algorithms Usage TRIZ Cases
- Secure Access Token Structure for Encrypted JWT Payloads
Selective JWT payload encryption keeps sensitive data protected on untrusted devices while preserving signature validation and backend compatibility.
- Self-Escrow Credential Unlocking for Secure Program Domain Access
Mutual authentication keeps escrow credentials inside the program domain, enabling authorized unlocking without backdoors or central key storage.
- AES S-Box Update Scheme for Side-Channel Resistant Encryption
Frequent S-box updates and a fusion function strengthen AES against side-channel attacks while keeping computational load low for IoT devices.
- IC Card Authentication Switching for Quantum-Resistant Security
Multiple authentication units let an IC card use quantum-resistant cryptography when available while preserving compatibility with existing systems.
- ZK-Rollup Transaction Batching With Parallel Trustless Aggregators
Parallel trustless aggregators batch ZK-rollup transactions and recursive proofs to improve liveness, cut on-chain cost, and speed finalization.
- Early Key Retrieval During OS Startup for Encrypted Partitions
An early retrieval process initializes networking before services.exe to fetch decryption keys and policies so encrypted partitions can mount during OS startup.
- IoT Command Transmission Using Local Asymmetric Key Protection
Local public-private key handling secures IoT command exchange during device setup, avoiding server-side key exposure and interception.
- IAB Hop-by-Hop Security Using Donor-Distributed Symmetric Keys
Donor-distributed symmetric keys protect hop-by-hop IAB messages from injection and fake link-failure attacks, reducing service disruption.
- Digital Resource Access Transfer for Cross-Blockchain Atomic Swaps
Private keys computed off-block enable secure atomic transfer of digital resource access across incompatible blockchains without trusted intermediaries.
- Endpoint Identity Obfuscation Through Traffic Blending and Path Randomization
Blending traffic into common internet patterns with layered encryption and randomized paths helps hide node identities and relationships.
- Multi-Link Wi-Fi GTK Update Synchronization to Cut Frame Overhead
Coordinated GTK updates across multiple Wi-Fi links combine key messages, reducing frame overhead and conserving radio resources.
- IC Card Multi-Authentication for Quantum-Safe Compatibility
Multiple authentication units let an IC card combine quantum-resistant and existing cryptography while safely controlling function access.
- Emergency Vehicle Authentication via RSU Relay for Fast Secure Clearance
RSU relay authentication uses shared secrets, ECC, PUFs, and biometric keys to secure emergency route messages without slowing lane clearance.
- ZK-Rollup Withdrawals Using Recursive Proofs and Parallel Aggregators
Recursive ZK-proofs and parallel aggregators keep ZK-rollup withdrawals live while reducing on-chain data posting and computation.
- Blockchain AI Model Training With Federated Privacy Control
Federated learning on blockchain keeps data local while smart contracts, consensus, and anomaly checks protect model integrity and privacy.
- Intermediary Certificate Mapping for Mutual TLS Authentication
An intermediary uses mapped client and server key pairs to preserve mutual authentication and establish secure sessions across both connections.
- Ciphertext Key Storage for Post-Reset External File Access
Encrypted key data is stored in a non-erasable partition so external memory files remain decryptable after a factory reset.
- SSO Authentication Mediation Across JWT, SAML, and OAuth
An intermediary SSO service translates JWT, SAML, and OAuth requests to cut integration complexity while preserving secure cross-entity access.
- Nonce Preprocessing for Low-Latency Cryptographic Messaging
Precomputed cryptographic states from freshness values cut message-processing latency while preserving security in real-time systems.
