Which process involves destroying the encryption keys used to encrypt data?

Crypto-shredding is the process that specifically involves the secure destruction of encryption keys used to encrypt data. By rendering these keys inaccessible, the encrypted data becomes irretrievable, as it cannot be decrypted without the keys. This method is particularly relevant in cloud computing and data security practices, ensuring that even if the data itself remains on a storage medium, it cannot be accessed or used without the corresponding encryption keys.

The effectiveness of crypto-shredding lies in its ability to protect sensitive information from unauthorized access. Once the keys are destroyed, the data is effectively rendered useless—underscoring the importance of proper key management and destruction protocols in maintaining data confidentiality and adhering to compliance regulations.

Other processes like data wiping and data sanitization generally focus on purging or cleaning the actual data from storage devices, which does not directly involve the encryption keys. Key management refers to the handling and organization of all cryptographic keys throughout their lifecycle, which does not encapsulate the destruction of keys specifically. Thus, crypto-shredding is the most accurate term for the act of destroying encryption keys.
