An organization needs to secure large volumes of data while replacing cryptographic secrets on a consistent cycle. Which approach relies on using a smaller secret to protect the main key, allowing more efficient exchanges of the key material?
Use short-term symmetrical secrets alone for each session
Rely on a single symmetrical key for every data set
Combine symmetrical encryption for data with an additional secret that secures cryptographic material
Refresh symmetrical keys for each data entry or change
Encrypting large amounts of data with symmetrical processes while using a smaller protector secret prevents time-consuming re-encryption of all data during secret rotation. Relying on a single symmetrical key complicates frequent changes. Replacing symmetrical keys every time content changes is also resource-intensive. Generating ephemeral symmetrical secrets without adding a further step can be less convenient for large-scale rotations.
