Which of the following cryptographic solutions would allow an organization to recover encrypted data after a key becomes corrupted or is deleted?

Self-signed certificates are used to establish secure connections and authenticate identities without the involvement of a Certificate Authority (CA). While they can secure communications, they do not provide a mechanism for key recovery if the encryption key is lost or corrupted, as they lack a third-party storage solution.

Tokenization replaces sensitive data with unique identification symbols (tokens) that retain the essential information without compromising security. While it secures data by removing sensitive information from storage, it does not facilitate key recovery for encrypted data, as it fundamentally alters the data format rather than providing a recovery mechanism for encryption keys.

A Trusted Platform Module (TPM) is a hardware-based security component that provides secure cryptographic functions and key storage. Although it enhances security and protects keys from unauthorized access, it does not offer a recovery solution for lost or corrupted keys. Once a key is lost, the TPM cannot retrieve it without a backup system in place like escrow.
