Cryptographic erasure
thecontinuitylayer.com/glossary/cryptographic-erasureThe definition
Encrypting each item or subject under its own key and deleting by destroying the key, so retained ciphertext, including backups, cannot be read. The established definition is in NIST SP 800-88 Rev. 2 (cryptographic erase). It does not reach plaintext that left the encrypted boundary, or a model trained on the item.
The same words the glossary hub and the public data mirror carry; this page is the stable address for the term.
