Re-keying is defined as?

Re-keying means changing cryptographic keys used to protect data. In PCI DSS terms, it’s about the lifecycle of encryption keys: generating new key material, replacing the old keys, and often re-encrypting stored data with the new keys while updating and retiring the old keys in the key management system. This practice limits how much data is exposed if a key is ever compromised and supports ongoing protection of cardholder data. The other options describe activities unrelated to cryptographic keys—renewing user accounts, resetting passwords, or applying software patches.
