Abstract
Methods, apparatuses, and systems are described for deriving secured keys and authenticating based on the derived keys. An entity may receive one or more derived keys and one or more key derivation algorithms associated with the one or more derived keys. A user device may derive, based on a key associated with the user device and unknown to the entity, a user key. The entity may derive, based on a first derived key and one of the key derivation algorithms, a second derived key, and may verify, based on the second derived key, the user key.
