US Patent 11664994 Secure unlock systems for locked devices

Technologies disclosed herein provide an apparatus comprising a fuse controller coupled to an aggregator. The fuse controller includes a plurality of fuses for storing a unique identifier of a device and a first secured value of a first password associated with the unique identifier. The aggregator is to receive the unique identifier and the first secured value from the fuse controller, send the unique identifier to an unlock host, receive a second password from the unlock host, compute a second secured value of the second password using a security function, and unlock one or more privileged features on the device based on the first secured value corresponding to the second secured value. In a specific embodiment, the first secured value corresponds to the second secured value if the first password is equivalent to the second password.
