The technique that enhances data security by destroying keys is crypto-shredding. This process entails securely deleting cryptographic keys, effectively rendering any data that was encrypted with those keys inaccessible. By destroying the keys, even if an attacker gains access to the encrypted data, they would not be able to decrypt it, thus protecting the confidentiality of the information.

Crypto-shredding is crucial in scenarios where sensitive data must be securely disposed of, such as when a business is no longer using certain data or when an employee leaves the company. The permanent destruction of keys ensures that the associated data cannot be recovered, providing a robust defense against data breaches and unauthorized access.

In contrast, key management involves monitoring and handling cryptographic keys throughout their lifecycle but does not inherently destroy them. Degaussing refers to the process of erasing data on magnetic storage devices, but it doesn't specifically target cryptographic keys. Enterprise DRM (Digital Rights Management) focuses on controlling the use and distribution of digital content but does not involve key destruction as a primary function.
