Multiple Keys/Algorithms Usage TRIZ Cases

TLS certificates and enclave attestations let third parties verify web-service data properties without modifying the service or seeing private data.

Changed LLM parameters are encrypted during training and decrypted only for authorized users, protecting confidential data during personalized inference.

Selective backpropagation updates only authorized LLM layers when training vectors contain private data, limiting exposure while preserving broader model training.

Encrypted delivery identifiers let distributors route items without exposing the recipient’s actual delivery point.

Fixed encryption schemes can expose network data to decryption attacks; managed, periodic switching improves resilience.

Selective FHE and PHE assign encryption to operation types, reducing compute and memory demands while protecting data in distributed 1-bit LLMs.

Token-specific key pairs and pre-registered references support secure, anonymous transfers without constant register communication.

Conventional proxy re-encryption creates long ciphertexts and costly operations; a lattice-based BGV approach enables batch evaluation for practical data sharing.

A communication device filters TLS version and encryption candidates to preserve compatibility while avoiding less secure communication settings.

See how terminals decrypt stored conference data and synchronize video and audio playback without giving the server full plaintext access.

Recipient-specific wrapped keys let an IoT data provider control each recipient independently while keeping data encrypted at rest and in transit.

Blockchain invitations and ledger-based permissions help electronic devices share data while limiting unauthorized re-sharing and preserving ownership control.

Single-system verification can be compromised; preconfigured rules require signatures from multiple independent systems.

Timeline bookmarks preserve an interrupted viewing position so content access authorization and missed segments can move to another device.

Messages carry a small record identifier and decryption key while recipients retrieve and verify encrypted user information.

See how hardware attestation and supermajority validation secure multi-cloud device admission without unrestricted blockchain growth.

Heartbeat notifications let load balancers prepare clients for server shutdowns, reducing timeout delays during network capacity contraction.

Static or scheduled key changes let eavesdroppers predict rotations; speaker identification triggers dynamic keys during group conversations.

An independent KACLS manages private keys and single-use DEKs, keeping email servers from seeing plaintext during decryption.

Sensor input and machine learning detect critical events, then release preconfigured data levels when the owner cannot authorize access.

A distributed blockchain lets mesh nodes encrypt communications, validate access, and receive payments without relying on a central authority.

Staged blockchain broadcasts and multiple signatures make resource access contingent on task completion while obscuring links to user IP addresses.

Dynamic de-identifiers separate sensitive identity data from AI-ready inputs, preserving analytics utility while enabling authorized, time-limited sharing.

Embedding digital certificates in CSI image frames lets hosts authenticate image sensors faster without repeated control-interface retrieval.

Preliminary cryptograms and encrypted challenges protect contactless card transactions from interception and replay while supporting scalable processing.

To address private-key leakage, the case splits key components across service terminals for collaborative session-data decryption.

A central terminal relays encrypted confidential records with open data to all user terminals, preserving anonymity while simplifying data-flow management.

State-qualified cryptographic material limits use to authorized IT components at the correct development or production stage.

Single-controller transponders can expose resource allocation; dual COMSEC encrypts host and hosted commands and telemetry for private payload reconfiguration.

Physical seals can be counterfeited; this case uses scan-ready codes and dynamic status checks to validate or invalidate digital signatures.
