摘要：
In one embodiment, an encryption system may protect user login metadata from hammering attacks. A data storage 140 may store an integrity protected data set 602 for an operating system in a storage location. A processor 120 may register a counter reading from a remote counter 202 in a secure location 204 separate from the storage location. The processor 120 may determine a lockout state of the integrity protected data set 602 based on the counter reading.
