Key rotation refers to the practice of regularly changing cryptographic keys used to secure transactions or data. This is aimed at enhancing security by minimizing the risk of key compromise.When users consistently use the same key over time, the likelihood of it being exposed increases. For example, if an attacker obtains a key, they can gain unauthorized access to assets or information. By rotating keys periodically, users can invalidate any previously compromised keys and reduce the potential for loss or theft.There are different methods for key rotation. Some systems do it automatically at set intervals, while others may require manual changes. The process can also involve generating new keys, retiring old ones, and ensuring that all relevant parties are updated with the new keys.Overall, key rotation is an essential practice for maintaining cryptographic security, ensuring that even if a key is compromised, the impact is limited to a specific timeframe. This helps protect users and their assets from long-term vulnerabilities.
