defense-in-depth cryptography
nounUsing many layers of secret codes so that if one layer breaks, the others still keep the information safe.
The app uses defense-in-depth cryptography, so even if one lock is picked, the data stays protected.

OTHER MEANINGS
2. A security strategy that combines several independent cryptographic methods to protect data.
Engineers applied defense-in-depth cryptography across storage, transit, and backups.
3. The practice of adding backup cryptographic controls so no single failure exposes secrets.
Defense-in-depth cryptography meant rotating keys and encrypting at rest and in transit.
4. A design principle in which encryption, authentication, and integrity checks all guard the same data.
