Abstract
A request for password generation is received from a host system. In response to receiving the request, a password derivation key is generated based on a key derivation seed. A password is derived from the password derivation key, and a wrapping key is derived from the password. The wrapping key is used to wrap an authorization state indication, which is stored in local memory. Encrypted data is generated based on an encryption of the key derivation seed using an asymmetric encryption key. The encrypted data is provided in response to the request.
