  "definition": "1. A purge sanitization technique in which key sanitization is applied to one or more keys providing confidentiality protections for the encrypted target data, making recovery of the decrypted target data infeasible.\n\n2. A method of sanitization in which the media encryption key (MEK) for the encrypted Target Data is sanitized, making recovery of the decrypted Target Data infeasible.\n\n3. See Cryptographic Erase.\n\n4. A method of Sanitization in which the Media Encryption Key(MEK) for the encryptedTarget Data (or the KeyEncryption Key-KEK) is sanitized, making recovery of the decrypted Target Data infeasible.",
