Abstract
A processing device initializes a memory device in an unauthenticated state in which the memory device is unable to execute one or more restricted commands. The processing device accesses a security capsule that is digitally signed using a private key. The processing device transitions the memory device to an authenticated state based on verifying that the security capsule is validly signed. The processing device uses a public key corresponding to the private key to verify the security capsule is validly signed. While in the authenticated state, the memory device is able to execute the one or more restricted commands.
