Abstract: The technology disclosed herein provides a method to control the resources used in a device. An implementation of such a method includes generating a device configuration ledger block based on initial assembly of components of a storage device, storing the device configuration ledger block on a node of a distributed ledger, detecting an activation of the device; in response to detecting the activation of the device, generating a current distributed ledger block based on current assembly of components of the storage device, comparing the current distributed ledger block with the device configuration ledger block, and in response to determining that the current distributed ledger block does not match with the device configuration ledger block disabling the operation of the device.

Abstract: Apparatus and method for performing authentication processing during device initialization. In accordance with some embodiments, a data storage device has a main memory which stores user data from a host, and a controller with initialization programming stored in a boot memory. The initialization programming is executed by the controller to transition the data storage device from an inactive state to a normal operational mode. During a bootstrap mode, the controller generates a first authentication token, receives a second authentication token responsive to the first authentication token, and authorizes use of new system programming responsive to the second authentication token. The new system programming is stored in a local memory of the data storage device and executed by the controller during the normal operational mode.
