Abstract
Systems, methods, and apparatus are provided for dynamic allocation of HSM disk space. A request to generate a data encryption key may be received and a set of logical HSM partitions scanned. When partition space is available for three keys, a set of three key versions may be generated. A first key state may be set to active and second and third key states may be set to pre-active. When no partition includes space for three keys, a new partition at the HSM may be initiated. When space is not available for a new partition at the HSM, a new partition at another HSM may be initiated. At a key rotation, partition metadata may be scanned to identify a key version in a pre-active state. The pre-active key version may be deleted, and a new active key version may be generated and stored in its place.
